Development of a multi-cohort analysis method and its application to the Indian Ocean yellowfin tuna [Thunnus albacares] length composition
A new multi-cohort model with the use of fishing effort as a tuning factor was developed and applied to yellowfin tuna (Thunnus albacares ) data of the Japanese longline fishery in the Indian Ocean from 1952 to 1980. The length compositions were converted to age compositions by means of normal curve...

description | A new multi-cohort model with the use of fishing effort as a tuning factor was developed and applied to yellowfin tuna (Thunnus albacares ) data of the Japanese longline fishery in the Indian Ocean from 1952 to 1980. The length compositions were converted to age compositions by means of normal curve fitting. The result of analysis showed a decrease of recruitment and population size. However, it should be noted that catches by the surface fisheries were neglected in the calculations. |
