Determination of Gillnet and Hook Selectivity for Caranx heberi Captured off Kanyakumari Coast of India | Chapter 12 | Advances in Applied Science and Technology Vol. 5
The larger carangids are most important fishery in the coast of Kanyakumari, Tamil Nadu. They are caught by large meshed gillnets and hooks in these region. However, there is no selectivity studies conducted on this fishery especially in this coast. The selectivity nature of every gear is important for managing the fishery as well as for conservation of resources. Large meshed gillnets having mesh sizes of 13.5 cm, 14 cm, 14.5 cm and 15 cm and Hooks No.5,6,7 and 8 were chosen for determining the selectivity and fishing power of the gears to capture the larger carangid Caranx heberi of Kanyakumari coast of India. The catch data were analysed using the software GILLNET (Generalized Including Log-Linear N Estimation Technique) comprised of the methodology of SELECT (Share Each Length Class Total) by fitting various uni-normal models viz., nor...
