Fisheries Data for the ICES Area
收藏资源简介:
Annual assessments are carried out for stocks of many species in the ICES area. These are brought together and reviewed by the Advisory Committee on Fisheries Management. Their report, published annually in the ICES Co-operative Research Report series, provides information on landings, recruitment, spawning biomass, fishing mortality etc. and also identifies the information sources, which are usually the reports of specific Working Groups. The information is derived from sampling or census (landings, number at age in the landings, weight at age, maturity) and from the output of various sequential population models (number at age in the population, fishing mortality). All the information is susceptible to revision as methods are revised, new data become available and models are re-run. Care is needed to understand how the information was derived and what it can be used for. The source documents should be consulted for descriptions of methods and also for information about stock areas, age of recruitment and other necessary details. This webpage offers Annual Summary information file from 2000 which provides the following information for each stock for each year: Species, Area code, Area name, Year, Number of recruits, Age of recruits, Year class of recruits, Spawning Biomass, Total landed weight of the catch, Mean Fishing Mortality, Ages included in mean F. Also available is material from 1998 assessments giving information for each stock for each year and for each stock*year*age.
