dc.description.abstract |
In the present study, an attempt was made to quantify hook selectivity of two
carangid species (Caranx ignobilis and Carangoides gymnostethus) which
were predominantly caught in the hook-and-line fishery off Negombo, Sri
Lanka. As the length frequency data of C. ignobilis and C. gymnostethus
recorded by hook size were skewed towards the larger fish, a modification of
Baranov-Holt method for gillnet selection was employed. For both species
there were positive significant relationships (p<0.001) between the hook size
and optimal length while selection range was negatively related to hook size
(p<0.001). |
