1. Change-in-ratio and index-removal methods for population assessment and their application to snow crab (Chionoecetes opilio)

   Abstract:  Change-in-ratio and index-removal estimators are presented in a general form suitable for fisheries studies. We also show how to combine the two approaches in a single estimator. It is necessary to sample the population before and after the fishery, and to determine the total harvest and

2. Relative selectivity of four sampling methods using traps and trawls for male snow crabs (Chionoecetes opilio)

   Abstract:  Catch rate and catch composition of male snow crabs were compared for four sampling methods. These methods were: (1) large-meshed commercial traps, (2) small-meshed traps, (3) bottom trawl deployed during the day. and (4) bottom trawl deployed at night. Catches were characterized in

3. Growth per molt of male snow crab Chionoecetes opilio from Conception and Bonavista Bays, Newfoundland

   Abstract:  Over 6000 male snow crabs were tagged during a 6-year period in Conception Bay, Newfoundland, in order to estimate the increase in size at the time of molting. Ninety-two animals were recaptured which had usable information on growth increments. Based on the amount of growth, we

4. Leslie analyses of commercial snow crab trap data: a comparative study of catchability coefficients

   Abstract:  If we could determine the relationship between catch rates in a trap survey and absolute population size, then we could estimate the standing stock of snow crabs before the fishing season from a survey conducted with traps. One way to calibrate the catch rates is to examine available

10. The preparation of recommendations and standard procedures for krill acoustic surveys

    Abstract:  Acoustic surveys are the most powerful tool of krill abundance estimation and distribution mapping. The International Community needs to prepare standard requirements and procedures for acoustic instrumentations to be used, as well as for survey design, data acquisition, processing,
