An inter-laboratory verification of ageing consistency for Atlantic herring (Clupea harengus harengus) of the Gulf of St. Lawrence was undertaken by two laboratories, the Maurice Lamontagne Institute (MLI) in Mont-Joli (Quebec) and the Gulf Fisheries Center (GFC) in Moncton, (New Brunswick). The new primary age reader and the secondary age reader of MLI were compared with the highly experienced GFC age reader. The two laboratories aged a total of 200 whole otoliths from the 2010 commercial fishery conducted in the northern Gulf of St. Lawrence; half of the otoliths were from NAFO Division 4R and half from NAFO Division 4S. Results are presented in terms of percentage agreement, total coefficient of variation (CV), Bowker’s test of symmetry, and age bias plots. The primary IML reader compared to the GFC reader resulted in 81.1 % agreement with a CV of 2.05 %. The secondary IML reader compared to the GFC reader yielded 66.5 % agreement with a CV of 3.58 %. The comparison of the two IML readers resulted in 71.8 % agreement with a CV of 2.74 %. In all three comparisons, Bowker’s test showed that there was no significant asymmetry. The levels of precision reflect the difficulty in the age determinations of these herring, being from catches in the summer and with a predominance of older fish.

The annual survey that scientists conduct on large research trawlers is an important source of information on the status of marine resources harvested in the estuary and northern Gulf of St. Lawrence. The main objective of the survey is to estimate the abundance and biomass of five commercially important species, i.e., Atlantic cod (Gadus morhua), Greenland halibut (Reinhardtius hippoglossoides), Acadian (Sebastes fasciatus) and deepwater (Sebastes mentella) redfish, and northern shrimp (Pandalus borealis). For several years, biologists have sought to improve the integration of stock status and ecosystem information, which has required a greater effort to better describe catches of other species of fish and invertebrates. The long-used sampling and observation protocol has evolved into a much more complex, detailed model. However, in implementing this protocol, difficulties have been encountered in accurately identifying ten or so species caught at each trawling station. This report provides a guide to the identification of fish species likely to be caught in surveys in the estuary and northern Gulf of St. Lawrence. This visual guide is designed as a practical tool for training staff and ensuring the quality of data collected. This report also describes the sampling and examination protocol for fish catches used for surveys conducted aboard the CGSS Teleost between 2004 and 2008 and presents a brief descriptive analysis of fish catches during this period.

Des relevés effectués au moyen de chaluts benthiques entre 2004 et 2008 dans le bas Saguenay, l'estuaire maritime et le nord du golfe du Saint-Laurent ont permis d'identifier à l'espèce plus d'un million de poissons. Les captures ont été largement dominées par quatre espèces de prédateurs d'intérêt commercial: le flétan du Groenland, deux espèces de sébaste et la morue franche, mais on a dénombré plus d'une centaine d'espèces dont la moitié peuvent être considérées rares sur les fonds chalutés. Les espèces les plus abondantes dans les captures étaient également celles qui furent répertoriées dans une plus forte proportion des stations échantillonnées. Les espèces inusitées possèdent une distribution soit boréale, soit méridionale, et fréquentent généralement le plateau continental ou même le talus continental au-dessus de la plaine abyssale dans l'Atlantique. Les données issues de ces relevés ne fournissent qu'une vision partielle des communautés de poissons dans le Saint-Laurent: les poissons pélagiques et estuariens étaient mal représentés dans nos échantillons, les fonds rocheux ou escarpés n'étant généralement pas chalutables. Ce vaste territoire d'environ I5O 000 km2 est peuplé d'une faune variée.©2009 La Société Provancher d'histoire naturelle du Canada Certains poissons sont communs, d'autres représentent des visiteurs occasionnels en provenance des profondeurs de l'Atlantique, mais tous sont fascinants. Encore aujourd'hui, l'écologie d'un grand nombre de ces espèces reste mal connue.

An Atlantic halibut (Hippoglossus hippoglossus) (41.4 cm fork length) with the same pigmentation on the blind side as on the ocular side (ambicoloration) was captured in the lower St. Lawrence estuary, Canada, on 24 June 2004. This specimen represents the most extreme case of ambicoloration published for this species to date. As in other cases of extreme ambicoloration, this specimen shows other signs of abridged metamorphosis and reduced asymmetry, such as incomplete migration of the left eye and a hooked dorsal fin. Studies of hatchery-reared larvae have shown that the most common cause of malpigmentation, including ambicoloration, in halibut is a diet containing inadequate amounts and proportions of essential unsaturated fatty acids shortly before metamorphosis. Even though not expected to be common in the wild, inadequate diet for a short duration before metamorphosis is the most likely cause of ambicolouration in wild halibut.©2007 The Ottawa Field-Naturalists'Club Transactions

Long time series of data are a source of invaluable information to put a current situation in a historical perspective. The data obtained from the scientific research surveys for the assessment of demersal fish and northern shrimp abundance conducted annually in the estuary and northern Gulf of St. Lawrence are regularly used for this purpose. The validity of these data is not questioned with regard to the identification of commercial species managed by our region, but this overall statement may not apply as well to the identification of non commercial fish species. Following a workshop held at IML in 2005, a working group has determined whether the data on the identification of non commercial species and commercial species not being managed by our region and collected between 1978 and 2003 are valid. For these species, the sampling protocol varied markedly over time. Not all fish were identified to the species level and in many instances very broad taxonomic levels were used. The identification of some species was inadequate, particularly in the Cottidae, Liparidae and Zoarcidae families. Overall, this data set must be used with caution if one is interested in the rare species, in measuring biodiversity, or in studying the temporal trends in the case of the species which are not managed by our region. In this report, we identify the weaknesses and suggest solutions to improve quality in the historical data as well as in the process of acquisition of new data.

Since the ratification by Canada of the United Nations Convention on Biological Diversity in 1992, various initiatives at documenting the underwater world have highlighted the need for more information regarding less familiar species. The Department of Fisheries and Oceans Canada (DFO) has been doing its part by using every available opportunity to try to document the marine biodiversity. Nonetheless, ship time on missions is precious and researchers are often confronted with the daunting task of quickly identifying various species, some of which are rarely caught in standard fishing gear. In order to improve the identification of species during marine surveys, the DFO Quebec Region Species at Risk team at the Maurice Lamontagne Institute has produced a bilingual field guide of marine species of fishes and invertebrates that may be encountered in the Estuary and Northern Gulf of St. Lawrence.

A systematic survey of scallop beds was carried out in 1993 on the Lower North Shore of Québec between Kegaska and Vieux-Fort. Subsamples were collected from the survey area (Iceland scallops) and from a small bay near Watagheistic Island (sea scallop and Iceland scallops) for histopathological analysis. Of the 303 stations established for the exploratory survey, only 109 stations were dragged because the others occurred on bottoms too deep or too rough to sample. Iceland scallops were present at 51 of the stations dragged, while no sea scallops were found at any of the survey stations. Only 7 stations had scallop densities greater than 10 per 100 m2. The age of the scallops ranged from 2 to 21 years with the dominant age classes of 11 and 12 years old. The mortality rate varied from 0.105 to 0.239, with the highest occurring near Kegaska. The growth rate and the slope in the linear relationship between shell size and muscle weight showed higher values in the western part of the survey area. Nearshore sampling is a small bay near Watagheistic Island revealed densities ranging from 0.16 to 8.99 per 100 m2 for sea scallops and from 0.14 to 6.81 per 100 m2 for Iceland scallops, respectively. The mortality rate here was very high, with means per station of 0.823 for sea scallops and 0.645 for Iceland scallops. The results from the nearshore sector in 1993 confirm a mass mortality phenomenon that has affected some of the scallops beds of the northern Gulf of St. Lawrence. The histopathological analysis revealed hemocytic infiltration, abscesses with necrotic blood cells and various parasites in many of the scallop tissue sections, especially from the digestive gland and gills. The prevalence of turbellarians was high, ranging from 35.7 % to 81.2 % in sea scallops and 5.3% to 60.0 % in Iceland scallops. Rickettsia-like inclusions and ciliates occurred at relatively high intensities, with maximums of 17.7 and 11.1 per cm2 of gill section, respectively. Nevertheless, the cause or causes of the massive mortality of scallops in this area could not be determined from the histopathological analysis.

The 1993 Quebec scallop landings were from, in order of importance, the North Shore (75 %), Îles-de-la-Madeleine (21.4 %) and the Gaspé peninsula (4.5 %). Fishing effort is quite dispersed in the northern Gulf of Saint Lawrence, except in Îles-de-la-Madeleine and the Lower North Shore where it is rather concentrated. Îles-de-la-Madeleine landings, effort and catch per unit effort increased with the arrival of a relatively good recruitment pulse in 1993. Research data revealed that reproduction in 1990 and 1991 was somewhat unsuccessful. Projections based on the prerecruitment index and the index of abundance of post-larvae predict a slight increase in available biomass in 1994 compared to 1993. On the Gaspé peninsula the landing pattern for the last twenty years shows that the sea scallop stock is overexploited. The presence of a dominant mode of 80 to 90 mm scallops in 1993 may result in an increase in available biomass in 1994. However, with the absence of prerecruits this would probably be only a temporary increase. On the Upper North Shore fishing effort is far too intense for the population and the instability of catch rates reflects the uncertainty of these beds. The significant decrease in CPUE over the last few years indicates a gradual depletion of the population. On the Middle North Shore fishing effort has decreased since individual quotas were assigned in 1991. The situation here is clearly different from that in the other regions of Quebec. On the Middle North Shore stocks are relatively abundant and exploitation is still largely maintained by accumulated biomass. As well, in areas 16G, 16E and 18A there are still several virgin beds of high scallop densities but which may have slow growth. On the Lower North Shore a progressive increase in size, the absence of young, and a massive mortality of sea scallops are disturbing. Fishing effort clearly surpasses the reproductive capabilities of the population. Exploratory fishing in 1993 in areas 15, 18C and 18D indicated the Island scallop was usually present over the whole territory but in weak abundance. An analysis of meat yield in relation to scallop whole weight (conversion factor) was carried out for the northern Gulf and the results indicated much variability both interspecific and intraspecific. The mean conversion factor is approximately 7.8 for the sea scallop and 6.6 for the Island scallop.

The scallop fisheries are divided into five sectors : Îles-de-la-Madeleine : Gaspé peninsula (Chaleur Bay, north Gaspé and south Anticosti); upper North Shore (Sept-Îles); Middle North Shore (Mingan Archipelago, Natashquan and north Anticosti); and lower North Shore. Quebec landings reached a summit in 1990 of 430 t of meat (3,572 t of live weight), worth $3.8 million. In 1991 and 1992, Quebec catches decreased with the establishment of individual quotas on the middle North Shore, and with lower catches in the Îles-de-la-Madeleine. Over the last seven years, the best yields have been from the middle North Shore. Following this, in order of importance, are the Upper North Shore, Îles-de-la-Madeleine, Gaspé peninsula and Lower North Shore. Commercial and research abundance indices indicate that scallops landings in Quebec should remain steady over the next few years, principally with the assignment of individual quotas and the possibility of finding new scallop beds in Middle North Shore sector. On the other hand, the traditional fishing sites near the Îles-de-la-Madeleine, the Gaspé peninsula, the Upper North Shore and the Lower North Shore are exploited at high rates that will not allow re-establishment of the stocks.
