When to count your eggs: Is fecundity in Greenland halibut (Reinhardtius hippoglossoides W.) down-regulated?
Fecundity in several fish species is subject to down-regulation by atresia so if fecundity is estimated many months before spawning, this will be an overestimation of the realised fecundity (actual number of eggs spawned). In order to get accurate measurements of fecundity it is important to have knowledge on when potential fecundity (estimated fecundity at time of sampling) closely resembles t...
متن کاملDeep-ocean predation by a high Arctic cetacean
A bioenergetic model for two narwhal (Monodon monoceros) sub-populations was developed to quantify daily gross energy requirements and estimate the biomass of Greenland halibut (Reinhardtius hippoglossoides) needed to sustain the sub-populations for their 5-month stay on wintering grounds in Baffin Bay. Whales in two separate wintering grounds were estimated to require 700 tonnes (s.e. 300) and...

متن کاملHistorical and Current Knowledge of the Greenland Halibut from Québec Fixed-gear Fishers in the Gulf of St. Lawrence
Fishing for Greenland halibut (Reinhardtius hippoglossoides) in the estuary and the Gulf of St. Lawrence (NAFO divisions 4RST) has been practiced mainly with gillnets by coastal fishers of Quebec and Newfoundland since the beginning of the 1970s. However, little information is available on the development of this exploitation, for example, on the evolution of the fishing practices. In 1997, a p...
متن کاملDoes increased information about reproductive potential result in better prediction of recruitment?
The relationship between stock size and recruitment is an essential element in the understanding of the productivity of a population. However, predicting the number of recruits produced by a population has proven to be a difficult challenge. This may in part be a result of poor estimation of reproductive potential (RP). We determined if including increased information on reproductive biology in...
