SUMMARY The information collected from the Mussel Monitoring Program (MMP) is provided to mussel growers and processors to assist in the management of their mussel farms and mussel harvesting plans. Staff of the Department of Fisheries, Aquaculture and Rural Development (DFARD) collected information related to mussel spat-fall, mussel meat yield, water temperature, the presence of potentially toxic algal species, tunicate larvae, and the presence of predators and fouling on mussel seed and grows-out lines. The information was collected from 33 mussel spat collection and growing areas over a period of 31 weeks in 2013. Information on mussel spat-fall prediction was collected from April 30 th to July 2 nd and on potentially toxic phytoplankton from September 4 th to November 27 th. Monitoring for the presence of potentially toxic phytoplankton was conducted in cooperation with the Canadian Food Inspection Agency (CFIA). The cooperation between CFIA and DFARD has resulted in a more efficient sampling program. In addition, water samples from mussel grow-out areas were examined for the presence of mussel larvae from July to late November. Growers often delay raising their crop and the socking of new mussel seed in the fall until the mussel spawning period is over and larvae can no longer be detected. This information assists the growers in avoiding a second mussel set on both new and old mussel crop. Mussel landings in 2012 were 50.0 million lbs, an increase of 4.0 million lbs over the landings in 2011. Landings for 2013 were not finalized at the time of printing of this report. The meat yield values of mussels collected from the monitoring stations in 2013 varied greatly (17-50 Canadian meat yield values) from area to area without evidence of apparent trends. There was an excellent set of mussel seed in most areas this year. Treatment for starfish, green algae and tunicates is very important in maintaining a good set of spat on collectors. There were no reports of seed shortage this year. Temperature data collected at each of the sample sites were within normal ranges for mussel growth and performance. - 1 -
There were high counts of Pseudo-nitzschia sp., from several north shore bays, in the water samples collected for the toxic phytoplankton monitoring portion of the program, however no toxins were detected in the analysis of mussel tissue. This is the first time since the fall of 2006 that high concentrations of Pseudo-nitzschia sp have been detected in water samples. There have been no elevated levels of domoic acid detected in shellfish since the fall of 2006 and, as a result, there were no closures of mussel harvesting areas due to presence of toxins. Tunicates continue to cause fouling problems for many mussel growers, with high densities of vase tunicates occurring in Montague River, Brudenell River, St. Mary s Bay, Murray River, Boughton River and Cardigan River. The vase tunicate continues to be observed in Souris River. For the fifth consecutive year, a joint intensive survey was conducted in the Nine Mile Creek area by Fisheries and Oceans Canada (DFO), the Atlantic Veterinary College (AVC) and our Department in mid September. No vase or clubbed tunicates were observed during the survey; however, the density of the violet tunicate remains high in the area. The density of the clubbed tunicate remains high in the March Water portion of Malpeque Bay and in Darnley Basin. Two clubbed tunicates were found on oyster gear in Savage Harbour in the spring of 2012; however, an intensive follow-up survey by DFARD and DFO was conducted in 2012 (and again in 2013 by DFARD) and this species was not detected. DFARD and AVC completed a follow-up survey in Tracadie Bay in September in response to seed being transferred to the area from Grand River last year, prior to a large clubbed tunicate being detected on a seed collection line. DFARD also completed a dive survey in Rustico Bay in mid August. Colonial tunicates have become well established in the bay; however, no solitary tunicates were observed. The clubbed tunicate was detected for the first time in Egmont Bay on oyster gear in November 2013. Colonial tunicates have become more abundant in several other north shore bays, including Darnley Basin, Southwest River and New London Bay. The two colonial tunicate species remain at high levels in Tracadie Bay, St. Peter s Bay, Nine Mile Creek and Savage Harbour. For information on the locations of all four aquatic invasive tunicates in PEI, see the invasive species locator maps in Appendix V. Tunicate larvae numbers, listed by species, are shown in Appendix I. Vase tunicate larvae were present in water samples from June 5 th until November 14 th. Peak vase tunicate larval count was - 2 -
from water samples collected from Murray River on September 17 th, with 200 larvae being counted in a 150 L water sample. Clubbed tunicate larvae were present in water samples collected in March Water and Darnley Basin from mid June until mid October, peaking in Darnley Basin on August 7 th, with 159 larvae detected. Information collected over the 2013 season was communicated to mussel growers via the use of a voice mail system and also through the Mussel Monitoring website at www.gov.pe.ca/go/musselmonitoring. - 3 -
INTRODUCTION The Prince Edward Island Mussel Monitoring Program (MMP) is a technical service provided to cultured mussel growers and processors by the Department of Fisheries, Aquaculture and Rural Development (DFARD). The MMP has operated annually since 1982 during the ice-free season providing mussel growers and processors with a variety of information to assist them in the management of their operations. Information is collected for the MMP on mussel spat-fall prediction, mussel meat yield analysis, water temperature, the detection and estimation of the numbers of potentially toxic algae species (such as the toxin producing diatom, Pseudo-nitzschia sp., and dinoflagellates, Alexandrium sp. and Dinophysis sp.), the presence and number of tunicate larvae, and the presence and quantity of predators and fouling organisms. As well, information on mussel meat quality of harvestsized mussels collected at the sample sites (i.e. meat yield and spawning condition) is made available over the season to the mussel growers and processing plants through the MMP. This information assists the processing plants in ensuring the consumer receives a high quality product. The department has expanded the role of the MMP over time in response to requests for additional information by the mussel industry. As well, the information collected for this program is often utilized by other government and academic research agencies and additional information has been collected for researchers when possible. The MMP has provided this assistance without substantially re-directing its resources from its mandate as a technical advisory service to the Prince Edward Island (PEI) mussel growers. In 2012, the cultured mussel industry produced 50,023,365 lbs of product for market with a landed value of $30,014,000, which was an increase in both landings and value, as compared to 2011 (Figure 1). The mussel industry is an important contributor to the PEI economy and has resulted in the creation of an estimated 1,500 full-time jobs and numerous spin-off industries. The economic value of the industry to PEI is estimated at over $60 million dollars. - 4 -
Figure 1. PEI mussel landings and values from 1980 to 2012. The mussels grown in PEI waters are of high quality because the growing areas are abundant in food and have excellent water exchange. The rivers and bays on PEI are well sheltered from prevailing winds making them ideal for mussel aquaculture. The objective of this report is to document the information that was communicated to mussel growers during the 2013 season through either the MMP website or through the dedicated phone message system. MATERIALS AND METHODS Equipment 17' Boston Whaler, 90 hp Mercury outboard motor and Shorelander boat trailer YSI temperature meter, Vemco automated temperature recorders, water pump (50L/minute capacity), 64 micron nitex screen for collecting mussel larvae, 20' clear plastic tubing (1.5" in diameter) and 2.5 gallon container Electronic weigh scale, calipers and cooking equipment for meat yield analysis Microscope, slides and pipettes for mussel larvae and phytoplankton observation Vacuum pump and filtering apparatus for phytoplankton slide preparation - 5 -
Field books, sample bags and cooler Computer and printer to analyze and store data Methods and Procedures The data collected by the MMP is to provide information on six main areas related to mussel aquaculture: 1. Mussel spat-fall prediction 2. Mussel meat yield 3. Water temperature 4. Presence of potentially toxic phytoplankton 5. Tunicate larvae sampling 6. Predators and fouling organisms Thirty-three mussel growing/spat collection areas are sampled weekly for the MMP (Figure 2). Maps demonstrating the specific locations of each of the sample sites are displayed in Appendix II. Figure 2. Sample collection sites for the Mussel Monitoring Program. - 6 -
1. Spat-fall Prediction The numbers and size range of mussel larvae were determined from water samples collected weekly at each of the sample locations from late April until early July. This information was used to assist mussel growers in predicting the timing and abundance of mussel spat-fall. The growers use this information to determine when to either deploy, or to raise and clean their collectors in order to maximize spat collection. Mussel larvae information was also collected from July to late November at some grow-out sites to provide growers with information on mussel second set. Some growers attempt to avoid or reduce the amount of second set from settling on market mussels by keeping the mussels submerged until mussel larvae are no longer detected in the water column. The growers also avoid the second set from settling on newly socked mussels by delaying the socking process until after the second set is complete. To collect mussel larvae for this analysis, water samples are pumped from the top two to three meters of the water column through a 64 µm screen at the rate of 50 liters per minute for three minutes (Figure 3). The mussel larvae become trapped on the screen surface and are washed off with 10 ml of previously screened seawater into a sample bottle. A 1 ml subsample of the larval concentrate is examined utilizing a compound microscope to determine the abundance and average size of the mussel larvae. The quantity of mussel larvae present is quantified according to the following scale: Low = 1 5 Medium = 6 15 High = >15 Figure 3. MMP field crew collecting water samples and water quality information. - 7 -
2. Mussel Market size mussels were held in wire cages at each monitoring station for meat yield analysis. Samples for meat yield analysis were collected from each of the monitoring stations from April 27 th to November 27 th. The following procedure is used for the determination of mussel meat yields: A. Thirty market mussels, 55 mm or greater in length, (generally 18-24 months old) are randomly selected and cleaned in fresh running water. B. Mussels are steamed in the absence of water for ten minutes, and then the meats are shucked from the shells. C. The steamed meat yield, expressed as a percentage, is determined according to the formula: = Steamed Meat Weight x 100 (Steamed Shell + Steamed Meat Weight) D. The European meat yield, expressed as a percentage, is determined according to the formula: European = Steamed Meat Weight x 100 Raw Weight of Sample Mussel meat yield information is beneficial to growers to assist in the determination of the mussel spawning condition in a river system. The information, when collected over a long-term basis, is of interest in the analysis of potential trends in mussel condition. This information is displayed graphically in Appendix IV. 3. Water Temperature Water temperatures were recorded from 1 to 2 metres below the surface at each site, at the time of each site visit, throughout the season (Figure 3). In addition, automatic temperature recording devices, set to record hourly temperature readings, were placed approximately 2 metres below the surface in several of the mussel growing areas. The hourly collected temperature data provided additional information on water temperature profiles throughout the ice-free season. This information assists growers in comparing temperature conditions with the development of mussel spawning condition over the season in various river systems. As well, in the event that shellfish mortality occurs, it is beneficial to have the information on temperatures over the season to assist in the investigation of the cause of the mortality. Temperature profiles taken - 8 -
from each of the mussel monitoring stations can be found in Appendix III and also in Appendix I for specific sampling days. 4. Phytoplankton Monitoring The monitoring for the presence of potentially toxic phytoplankton began on September 4 th and continued until November 27 th in 2013. It is during this time period that toxic algae blooms have most frequently occurred in PEI waters. This portion of the program was conducted in conjunction with the Canadian food Inspection Agency (CFIA) who share in the collection of samples with staff of the MMP. The procedure utilized to collect, identify and quantify potentially toxic algae is documented in the DFO procedures manual A field and laboratory manual for the collection, identification and enumeration of toxic marine phytoplankton by John C. Smith and Kevin Pauley. Department staff collected water samples weekly from sites in Boughton River, Brudenell River, Cardigan River, Covehead Bay, Murray River, Savage Harbour, St. Mary s Bay, St. Peter s Bay and Tracadie Bay. Mussel samples were also collected by department staff from these sites for the CFIA toxin monitoring program. CFIA staff collected water and mussel samples from Darnley Basin, Lennox Channel, March Water, New London Bay, and Rustico Bay for both programs. Information on the identification and quantity of potentially toxic phytoplankton species observed in the water samples were reported to CFIA and also were made available to growers on the MMP website and voice mail message system. The numbers of algal cells observed were reported according to the following scale: Trace = 1-1000 cells/l Low = 1000-50,000 cells/l Medium = 50,000-350,000 cells/l High = greater than 350,000 cells /L The results of the phytoplankton analysis for 2013 are reported in the results section of this report (Appendix I). The information collected from this portion of the program is beneficial to provide both industry and CFIA with an early warning of the possibility of a bloom of potentially toxic algae occurring in an area. The presence of toxins in mussel tissue is monitored by CFIA, - 9 -
and closures are based upon these levels; however, the information on the types and quantity of phytoplankton present in the water column is invaluable as early warning that an event might occur. If the samples show that numbers of a potentially toxic algae species are present and increasing in a river system CFIA may increase their sampling of mussels from the area and industry can plan future mussel harvests avoiding the algae bloom and ensuring that a safe product is sold to the market place. 5. Tunicate Larvae The numbers of tunicate larvae (vase, clubbed, violet, golden star) were counted in water samples collected from tunicate infested areas (see Appendix I for numbers of tunicate larvae). The purpose of obtaining the larvae numbers was to: inform growers when the tunicates start and stop spawning, the species of tunicate larvae present, and to provide an indication of the amount of larvae that were present over the season. Recent research results have shown that there may not be a direct correlation between the timing and density of tunicate recruitment and the observation of tunicate larvae and larvae densities in the water samples collected for MMP. However, this information is still considered to be worthwhile to collect and may show an indication in trends in changes in tunicate populations over time. Tunicate counts were conducted weekly from mid-june to early December. Water samples were collected by pumping water through a 64 µm sieve using a water pump at the rate of 50 L per minute for 3 minutes (a total of 150 L per sample). Tunicate larvae were identified and counted in the entire water sample. The larvae counts were made available for the growers on the MMP website and voice mail message system (1-800-454-3233). 6. Predator and Fouling Monitoring Spat lines were examined for the general appearance of the crop and for the presence of predators (such as starfish and sea ducks), fouling organisms such as algae, hydroids, tunicates or sea anemones and also for the presence of silt. Mussel growers are notified if large numbers of starfish were observed on spat lines, or of any other potential problems that are noted by technical staff. In the fall of 2013, staff worked with Bob Thompson, a consultant hired by the PEI Aquaculture Alliance to coordinate sea duck surveys and to test new techniques to deter ducks from predating on cultured mussels. If growers observe any unusual fouling organisms or - 10 -
aquatic invasive species that are outside of their known range they are asked to either contact this department or Fisheries and Oceans Canada (DFO). Staff of either department will be available to identify the organisms and provide more information on the species. Information and maps showing the current known ranges of all aquatic invasive tunicates in PEI waters is available on the MMP website, in Appendix V of this report, or may be obtained by contacting staff of either our department or DFO. Reporting The information collected from the MMP is made available throughout the field season through a telephone voice mail message system and also through the mussel monitoring website. In addition, the previous year s MMP reports are available on the DFARD website. Mussel growers are able to access this information at any time. The telephone numbers are Charlottetown exchange 368-6510 and long distance 1-800-454-3233. The web address is www.gov.pe.ca/go/musselmonitoring RESULTS AND DISCUSSION Information collected on quantity and size ranges of mussel larvae, meat yields, water temperature, numbers of potentially toxic algae and tunicate larvae from each monitoring location are presented in the tables in Appendix I. A high quantity of mussel seed was collected in most areas in 2013. High numbers of setting size mussel larvae were observed in water samples at most locations from mid June until early July. In 2013, high numbers (greater than 350,000 cells/l) of Pseudo-nitzschia sp. cells (Figure 4) were observed in some locations. In past years, there were frequent fall blooms of Pseudonitzschia sp., which provided a significant food source for cultured mussels prior to the winter period. However, there have been no closures to mussel harvesting due to domoic acid toxicity since 2006. For example, in Cardigan River the numbers of Pseudo-nitzschia sp., (a non-toxin producing form), peaked in the late fall of 2001 at 5.6 million cells/l of seawater and in 2002 at - 11 -
9.3 million cells/l. In 2013, the peak numbers of Pseudo-nitzschia sp. cells was 3.2 million cells/l (Lennox Channel). Since 2007, there have been extensive blooms of Chaetoceros sp., along with other algae species, which are also excellent food sources for mussels. Figure 4. Pseudo-nitzschia sp., a potentially toxic phytoplankton species. Invasive tunicate species continue to cause fouling problems for the mussel industry. There are four invasive tunicate species located in PEI waters: the solitary clubbed and vase tunicates and the colonial violet and the golden star tunicates (see Appendix V for maps showing the most current tunicate distribution). The clubbed tunicate remains at high levels in the March Water area of Malpeque Bay and in Darnley Basin, while numbers continue to remain low in New London Bay, Orwell / Vernon Rivers, Souris River and Grand River. Two clubbed tunicates were found on oyster gear in Savage Harbour in the spring of 2012; however, an intensive follow-up survey by DFARD and DFO was conducted in 2012 (and again in 2013 by DFARD) and this species was not detected. DFARD and AVC completed a follow-up survey in Tracadie Bay in September in response to the transfer of mussel seed from Grand River last year, prior to a large clubbed tunicate being detected on a seed collection line. DFARD also completed a dive survey (Figure 5) in Rustico Bay in mid August. Colonial tunicates have become well established in these bays; however, no solitary tunicates were observed. The clubbed tunicate - 12 -
was detected for the first time in Egmont Bay on oyster gear in November 2013. The density of the vase tunicate continues to be very high in the Montague and Brudenell Rivers, St. Mary s Bay, Murray River, Cardigan River and Boughton River. A population remains in the Souris River, where it was first identified in 2010. Colonial tunicates have been detected in all mussel production areas on PEI, with the exception of North Lake. Figure 5. DFARD staff completing dive survey (Bideford River) for the presence of aquatic invasive species. Currently, there are restrictions on shellfish transfers into and between areas due to tunicate infestations. For the most recent information on the restrictions please contact the local DFO office. Maps depicting the locations of the aquatic invasive tunicates in PEI are displayed in Appendix V, and may also be viewed on both the MMP and DFO s websites. Tunicate larvae numbers, by species, which were detected in the water samples, are shown in Appendix I. Vase tunicate larvae were present in water samples from June 5 th until November 14 th. Peak larval count of the vase tunicate was in Murray River on September 17 th with 200 larvae being counted in a 150 L water sample. Clubbed tunicate larvae were present in water samples collected in March Water and Darnley Basin from mid June until mid October, peaking in Darnley Basin on August 7 th with 159 larvae detected. - 13 -
Sea duck predation on newly socked mussels continues to be a problem in PEI. With the apparent trend of warm weather occurring later into the fall and milder winters with ice cover occurring for shorter periods, there has been more opportunity for ducks to feed on newly socked mussels. Sea duck predation has been observed on mussels in the spring of the year since 2006. This appears to be a new trend in feeding behavior of migrating sea ducks, (previously predation problems were only noted in the fall of the year). The most problematic species are scaup, longtailed ducks and scoters (Figure 6). Figure 6. Problematic duck species, including scaup (Top), long-tails (Middle) and scoters (Bottom). - 14 -
DFARD, worked jointly on a project with DFO, the Canadian Wildlife Service (CWS), the Prince Edward Island Aquaculture Alliance (PEIAA) and Industry to investigate new deterrent techniques (i.e. Phoenix Wetlands Wailer, see Figure 7), and to conduct surveys to determine sea duck population dynamics. Figure 7. 'Phoenix Wetlands Wailer being tested as sea duck deterrents. Despite the challenges facing the mussel industry, including sea duck predation and tunicate fouling, landings continue to grow each year. In 2012, landings reached a new high of 50,023,365 lbs, with a landed value of $30,014,000. The industry, as a whole, has shown a remarkable ability to innovate, developing new technologies and growing practices to overcome these challenges. - 15 -
