Book Description
The majority of the larvae released in the top 10 m at the outer reaches and within the confines of Lobster Bay remain in the inshore region with the majority being advected to the St. [...] However, the fall-spring period represents the majority of the catches and the highest catch rates and the authors believed events in that season to be indicative of trends the fishery. [...] For example, no attempt was made to separate the catch rates of the various boats and crews, thereby confounding differences among the fishing powers of the boats with changes in the calculated catch rates of the fleet. [...] With respect to the analyses, the fact that no residual patterns were observed (a point stressed in the presentation) might only be a function of the large number of parameters in the analyses and not assurance of the appropriateness of the model to the data. [...] The shift in median size could result from a number of causes such as seasonal movement of animals through the grounds, change in size-related catchability due to the recent cold water conditions, a recruitment pulse increasing the numbers in the smaller sizes (as observed in the Bay of Fundy fishery), or subtle changes in fishing practices, areas and gear.
