This document contains the proceedings from the meeting held within the regional assessment process on softshell clam in the Quebec coastal waters in Quebec region following the 2007 fishing season. This advisory process was held on November 20, 2007 at the Maurice-Lamontagne Institute in Mont-Joli. During this meeting, the assembly reviewed the stock status of the softshell clam in the Quebec coastal waters exploited by both commercial and recreational fishery as well as certain environmental parameters that prevailed during the last fishing seasons. Therefore, these proceedings contain the essential parts of the presentations and discussions held and relate the main recommendations and conclusions that were presented during the review.

Little is known of the growth of the sculptured shrimp Sclerocrangon boreas, a remarkable member of arctic and subarctic marine shelf communities. We determined the length-weight relationship, abdomen allometry, and size structure of shrimp in a population of the Gulf of Saint Lawrence, eastern Canada. We also reared shrimp for up to 3.5 years to measure their growth. The presence of very small immature females in the wild population indicates that the sculptured shrimp is not obligatorily a protandric hermaphrodite, if at all. Females grow faster, reach a greater size, and live longer than males. Males may be ≥4 years old at 17 mm cephalothorax length (CL) and females ≥6 years old at 29 mm CL. Ovigerous females have a broader abdomen with longer pleopod setae than similarly-sized immature females. After releasing their progeny, some females may molt and grow in length but revert to a condition of narrow abdomen and short pleopod setae, and then molt again to a condition of broad abdomen with long pleopod setae. This finding and demographic data suggest that some females are alternate-year spawners. Other females did not molt for ≥2 years and may spawn in successive years.©2007 The Crustacean Society
