Abstract

The highly migratory nature of the skipjack tuna (Katsuwonus pelamis) coupled with inadequacy of data which is likely to pover only a fringe of its entire geographical distributior range poses problems in the estimation of population parameters and stock size of this species. The present study is ar attempt to evaluate estimates of these parameters based or pole and line fishery data collected during 1985 and 1986 at Minicoy, Lakshadweep only. Problems encountered in the estimation of migratory stocks as exemplified by skipjack tuna are presented and discussed.
