|Ship name (ship code)||FV Helenus (74OQ)|
|Cruise period||2001-12-02 — 2001-12-07|
|Port of departure||Fraserburgh, United Kingdom|
|Port of return||Fraserburgh, United Kingdom|
|Objectives||To collect biological data on the gadoid populations (cod, haddock and whiting) at two geographcally contrasting sites: Inshore - North Minch; Offshore - Butt of Lewis.
This charter is one of a series of surveys in both the North Sea and off the west coast of Scotland. These surveys are to be performed bi-monthly and the collected data will allow:
a) Comparison of inshore and offshore gadoid populations, with respect to size structure, growth, age composition and condition indices;
b) Description of temporal variation in these condition indices; and
c) Development of unbiased bi-monthly growth curves for the target gadoid species.
This project will be conducted as a preliminary exercise to assess the feasibility of using commercial vessels to supplement the collection of biological data on key commercial stocks.
