Scientists from Fisheries and Oceans Canada (DFO) and from the Ministère des Ressources naturelles et de la Faune du Québec (MRNF) and the Ministère du Développement durable, de l’Environnement et des Parcs (MDDEP) met on March 17th and 18th, 2009 to review the available information on the copper redhorse habitat. The meeting’s objective was to assess the copper redhorse habitat use and to determine the quality of this habitat. A second workshop will take place in the winter of 2010 to complete the work. The scientific information presented during the meetings will help in drafting the science advice for identifying this species' critical habitat henceforth listed as an endangered species in the Species at Risk Act (SARA). A summary of the different federal laws and guidelines that regulate the identification and protection of the copper redhorse critical habitat was first presented to the participants. The MRNF then presented more technical presentations on the principal characteristics of the copper redhorse: distribution, abundance, status and biology. Information updates were provided concerning the copper redhorse habitat used at various stages of development and thus certain characteristics or important sites were identified in order to protect the habitat. The two known spawning grounds (Chambly Rapids Archipelago and the area downstream from the St. Ours dam) on the Richelieu River should be protected as well as the feeding and rearing areas located in the river corridor between Montreal and Sorel. The importance of maintaining a free passage between the St. Lawrence and the spawning sites in the Richelieu River was also mentioned. The grass beds along the shore in shallow water areas, in particular the left shore of the Richelieu River and around the Jeannotte and Aux Cerfs Islands in the Richelieu River, were identified as key copper redhorse nursery areas (rearing, feeding, shelter). On the other hand, it was mentioned that knowledge on immature copper redhorse was very fragmentary, limited to historical captures throughout the species’ distribution range. Modelling results from the adult copper redhorse occurrence site characteristics provided a first look at the species’ potential habitat. Additional analyses will be conducted over the next few months and will be presented at a future workshop. Finally, it was noted that the copper redhorse occurs in waterways located among the most densely populated areas in Quebec and that the deterioration and fragmentation of its habitat represented the primary threats to its recovery.

In 2004 and 2005, there was work conducted in cooperation with the industry to acquire data on the growth rate of the Stimpson’s surfclam, to assess the resilience of local populations to high exploitation rates, and to estimate the species’ recruitment. Surveys were made on the Longue-Pointe-de-Mingan Stimpson’s surfclam natural bed using a grab sampler, a video camera and a hydraulic dredge. A tagging and recapture experiment was also conducted on two experimental parcels. Age estimates from growth lines on the chondrophore of the surfclam’s shell as well as growth datameasured from tagged individuals indicated that the Stimpson’s surfclam is a slow growth species. Based on our results, between 13-20 years would be required for reaching respective lengths of 80-100 mm. Average catches per unit of effort of surfclams (standardized per fishing hour and for a 1 m wide dredge) varied between 292 and 442 kg/h·m for two parcels and for both experimental years. The effort deployed during the experiments did not show any Stimpson’s surfclam depletion on the two Longue-Pointe-de-Mingan clam bed experimental parcels. The exploitation rate estimates for the tagging - recapture project during the 2004 directed fishery were respectively 11 % and 17 % on experimental parcels M-1 and M-2. However, different factors (e.g. mortality, vulnerability, loss of tag) were likely responsible for under estimating exploitation rates. The mean numbers per unit of effort (all sizes confounded) were 1,200 surfclams/h·m near parcel M-1 and 1,785 surfclams/h·m near parcel M-2 when a doubled dredge was used. Recruitment appears to be more homogeneous at the parcel scale (100-200 m) than in the scale separating the two experimental parcels (2.4 km). Results from the work carried out in 2004 and 2005 tend to show that knowledge acquisition concerning exploitation and Stimpson’s surfclam population dynamics is complex. The use of alternative methods, such as the grab sampler, the video camera and the dredge doubled with fine mesh, is necessary for better understanding the abundance of young urfclams and their habitat on the fishing ground. This information will help develop exploitation and conservation strategies that account for the low growth rate of this sedentary species.

A two-day workshop on redfish was held at the Maurice Lamontagne Institute on September 19th and 20th, 2007. This meeting gathered nearly 40 participants from research to management to industry. There were three objectives on the agenda. First, review the information on redfish (Sebastes sp.) available from the Department of Fisheries and Oceans (DFO) Science sector for the assessment by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). In fact, in its call for bids of the fall of 2006, COSEWIC was requesting that a report be produced on the status of redfish (Sebastes fasciatus and S. mentella), which triggered the assessment process for these species. The second objective was to present the recent data on the stock structure of redfish in the Northwest Atlantic in order to determine the biological relevance of management units 1 and 2. This objective followed a zonal workshop (DFO 2006) where the discussions did not lead to any consensus. The last objective of the workshop was to re-examine the relevance of maintaining the redfish index fishery in Unit 1, which has been under moratorium since 1995. Examining the information on redfish led to the discovery of complex structure patterns, but also to some reflection on the value of the data obtained and the methods used. The second objective led to a series of recommendations, including consolidating Units 1 and 2 into one unit for each of the two species: S. mentella and S. fasciatus. It was also recommended to consider the complexity of the structure patterns in the assessment process and in developing management and conservation measures. Finally, the meeting did not lead to any conclusion in terms of the relevance of maintaining the index fishery in Unit 1. It was suggested to conduct a redfish stock assessment by considering the overall data, including the index fishery data, prior to agreeing on this issue.

Recovery Potential Assessment (RPA) and associated socio-economic analysis are required to inform the decision on whether or not to list a species under the Species at Risk Act (SARA). RPA should also provide the basis for the Recovery Team to develop a Recovery Strategy and Action Plan after listing. While DFO has considerable experience in providing short-term scientific advice in support of fisheries management, approaches constituting best scientific practice and standards for long-term advice in support of listing decisions and recovery planning are still developing. Biological processes are best captured in a life-history model. This model needs to deal with both observation error and process error. Uncertainty associated with process error expands rapidly in projections beyond three years and methods have to take this into account. Bayesian state-space approaches provide a way of incorporating both observation and process error in the analysis. In most cases management strategy evaluation (MSE) of performance relative to a simulation of the biological process, assessment process and management process (operating model) may have the greatest potential given difficulties associated with making long-term quantitative projections. This approach could be expanded to include socioeconomic aspects. Scientific analysis can be completed as a first step and the results then passed to Policy and Economics to undertake socio-economic analysis. This twostep approach is considered to be less attractive than a fully integrated approach in which scientific and socio-economic analyses are undertaken and peer reviewed in a joint assessment. The current review was unable to fully develop the best-practice standard without further work. In order to make progress it is recommended that DFO management chose an upcoming high-profile RPA as a national case study to establish a best-practice standard for the preferred fully integrated biological/socio-economic approach that is described. The case study should include establishing independent socio-economic and scientific peer review, and public communication of expert advice on recovery potential and cost-benefit of alternative recovery options, independent of the political process of determining SARA listing.

Mollusc and echinoderm production comprises actually the whole of the Quebec mariculture industry. While it is still consolidating, this industry is shortly expected to become profitable. Working in the context of diminishing resources, SODIM and MAPAQ occasionally receive financial support requests concerning start-up projects for Atlantic halibut, wolffish or Atlantic cod production. The time seemed propitious to assemble researchers, promoters, mariculturists, ministry as well as resource conservation and economic development organism representatives in the Atlantic region, in order to discuss marine finfish culture as an avenue of development of the Quebec maritime regions. Quebec researchers are actually developing techniques for winter flounder and wolffish culture. Elsewhere in the Atlantic, codfish and halibut culture are in the pre-commercial stage of development. However, they are plagued by financial problems of sufficient proportion that may seriously compromise their commercial future. Elsewhere in the world, Norway, Iceland and Scotland have started commercial ventures of one or the other of the following species : Atlantic wolffish, cod and Atlantic halibut. The results of the discussions of this workshop indicate that Quebec conditions are actually difficult for marine fish culture. As well, there is not sufficient knowledge to reduce the associated risk to a level which would attract the private sector. State funding is required for financing the development of these cultures at this stage. Even so, the 70 or so participants maintain their interest and wish to increase communication and consultation among the interested parties.

Shellfish culture is in effervescence in the Province of Quebec. Technological innovations enable the increase of production volumes and help to sustain the constantly growing demand. Some techniques like spat transfers also permit to improve the performance of culture farms. These transfers must be safety executed in order to avoid disease propagation that could strongly affect the production. Thus, a histological health survey has been conducted in 2004 and 2005 on different culture and experimental marine shellfish sites in order to establish a data base essential to accurately differentiate primary pathogens from opportunistic ones taking advantage of sub-optimal culture conditions. This data base also includes all the results of health reports realized since 1999. The targeted species were blue mussel, Mytilus edulis, softshell clams, Mya arenaria, giant scallops, Placopecten magellanicus and Iceland Scallops, Chlamys islandica. Histological examination revealed the presence of largely observed organisms such gills, digestives gland and intestine ciliates, gigenean metacercarian cysts, Rickettsia-like organisms and copepods. Pathology or pathogen observed such as Prosorhynchus squamatus and haemic neoplasia are disease concern in Atlantic Canada and require a stronger monitoring.©2007 Aquaculture Association of Canada

A zonal workshop of one-day was held in order to examine new elements concerning the distinction of redfish stocks in Units 1 and 2 within the context of the current management approach. During the meeting held on February 9th, 2006, participants studied the most recent data concerning population structure of Northwest Atlantic redfish stocks. Specifically, genetic and geometric morphometric data as well as data on the elemental composition of otoliths were examined. The discussions that were held during the workshop were not entirely conclusive as to the biological relevance of the management units currently used for redfish. Nevertheless, it was agreed to that this point be added to the agenda of a future workshop, which should be held within a few months.

This document contains the proceedings of the meetings made within the framework of the regional stock assessment process of the Quebec region following the 2004 fishing season. This advisory process was carried out from December 14, 2004 to February 17, 2005 at the Maurice-Lamontagne Institute, Mont-Joli. During these meetings, the stock status of several marine species commercially exploited in the Estuary and the Gulf of St. Lawrence, and some of the environmental parameters prevailing at the time of the 2004 fishing season were reviewed. These proceedings document the major points presented and discussed during the meetings and also present the principal recommendations and conclusions that were made at the time of the review.

Exploitation of the rock crab (Cancer irroratus) on Canada's Atlantic coast is relatively new. Experimental fishing began in the southern part of the Gulf of St. Lawrence in 1974. In Quebec, markets developed later, and fishing began only in 1988. After a mere two years of operation, fishing practically ceased for lack of buyers, but a new start was made in 1995. When fishing first began, the Department of Fisheries and Oceans implemented a management plan to control development of this new fishery and maintain the population's reproductive potential. Fishing is regulated by a minimum legal shell width of 102 mm (4"), a ban on landing females, use of selective gear to minimize lobster (Homarus americanus) catches, and a limit on trap numbers. The number of licenses is limited in certain areas, as are catches. In 1997, Quebec rock crab landings reached 1,040 t, a 51 % rise from 1996. In the Gaspe, landings totalled 592 t, accounting for 57 % of Quebec landings. In the Magdalen Islands in 1997, landings increased by 125 % compared to 1996, reaching 448 t. They represented 43% of Quebec landings. The rock crab fishery is still expanding and the opening of new fishing grounds in 1997 contributed to the increase in landings. In the Gaspe, catch rates have been falling since 1995, quite steeply in some areas. In the Magdalen Islands, 1997 catch rates were lower than in 1996 but equivalent to those of 1995. Declining catch rates may reflect depletion of the accumulated biomass of these virgin stocks, but they could also be due to changes in fishing patterns in space and time in relation to seasonal crab movements or changes in the pattern of abundance that could be cyclic. At present, it is hard to detect the effects of harvesting on the populations. We insist on the need for slow and cautious development of this fishery because of concerns over the possible impact of rock crab harvesting on lobster stocks. The two species interact sufficiently to justify strict and cautious management of the crab fishery.

The distribution of rock crab along the coast of Québec was studied to determine its seasonal pattern of migration. More specifically, we wanted to examine the hypothesis that the rock crab migrates seasonnally, first concentrating is shallow water in spring, then dispersing during summer. Sampling was done in 1991 off Anse-à-Beaufils, Québec, during the months of April, August, September and October. Additional observations were made during spring, off Carleton, Ste-Marie-sur-mer and Caraquet. Sampling was done using conical japanese traps. Samples were also obtained using a beam trawl and by SCUBA diving. In spring, rock crabs are mainly found in shallow water (10 m), on soft substrates, where they have apparently spent the winter. In summer, rock crabs appear to migrate to greater depths, possibly deeper than 40 m. Rock crabs would return to shallow water in fall where they seem to concentrate until the next spring. Their presence from fall until spring on soft substrates could be advantageous. Burying themselves in could provide protection for rock crab during their molting period. Although rock crab densities were lower in Ste-Marie-sur-mer and Caraquet when compared to Anse-à-Beaufils, we noticed that the highest concentrations of rock crab were again associated with soft substrates (sand-mud), and were generally in shallow water. The dispersal of rock crabs during summer could be conditionnel by a process of avoidance of warm water (> 12 °C). Also, after the molting period, the requirement for a soft substrate would be less. In summer, rock crabs are found on various type of substrates, apparently in accord with their availability and accessibility. These observations add to our knowledge of the nature and dynamics of rock crab along our coasts. Knowledge of the distribution patterns for rock crab, on which depends directly the yield of a fishery, will help users of this resource better plan their fishing activities.

Exploratory fishing took place during the summer of 1993 in the Gaspé-Nord region, between Capucins and Gros Morne, to determine if there were lobster concentrations large enough to sustain a commercial exploitation, and to determine the type of fishing that could be practiced. The exploratory fishing took place from July 5 to August 7, 1993. At first, fishing proceeded along predetermined transects. Then, fishermen were allowed to fish wherever they wished inside the designated zones. During the first phase of the exploratory fishing 8 lobsters were caught in a total of 1229 traps. During the second phase, 216 lobsters were caught for 3381 traps hauled. Most lobsters were caught in shallow water (3,6 to 10 m depth) inside zone 5 (Rivière-à-Claude to Gros Morne). Lobsters were large (95,0 and 97,7 mm CTL on average for females and males, respectively). In general, lobster biomass in this region is very low, growth is presumably slow and the reproductive potential low. The presence of a few small lobsters (60 mm CTL) suggests that there could be local recruitment of young lobsters. Local larval production however is probably exported. Therefore, the local stock is probably dependent on the production originating from other regions, either via larval transport or migration of individuals in the benthic stage. Our results suggest that lobster exploitation in this region would produce small yields and be of short duration if the recruitment is sporadic or slow. The establishement of conservation measures to protect the reproductive potential is questionable. First, the reproductive capability of the lobster population of Gaspé-Nord has not been demonstrated and second, such measures would not have any local impact. They would only benefit to populations that are dependent on the Gaspé-Nord population, which are unlikely to exist.
