Length–weight relations of pelagic fish species from eastern region of Java Sea, Indonesia
Saleh,M. | Soegianto,A.
The present work estimates length–weight relations (LWRs) of fish species from eastern region of Java Sea, Indonesia. The fishes were caught by purse seines. A total of 2461 specimens belonging to five families and 12 species were analysed: Caranx sexfasciatus Quoy et Gaimard, 1825; Decapterus russelli (Rüppell, 1830); Elagatis bipinnulata (Quoy et Gaimard, 1825); Megalaspis cordyla (Linnaeus, 1758); Parastromateus niger (Bloch, 1795); Selar crumenophthalmus (Bloch, 1793); Sardinella longiceps Valenciennes, 1847; Euthynnus affinis (Cantor, 1849); Rastrelliger kanagurta (Cuvier, 1816); Scomberomorus commerson (Lacepède, 1800); Sphyraena barracuda (Edwards, 1771); Lepturacanthus savala (Cuvier, 1829). The b values of the LWRs ranged from 2.407 for Sphyraena barracuda to 3.510 for Lepturacanthus savala. The presently reported study is the first report on LWRs of pelagic fish species at least from eastern region of Java Sea. Five species of fish such as Decapterus russelli, Parastromateus niger, Rastrelliger kanagurta, Scomberomorus commerson, and Sardinella longiceps have been studied especially in western region of Indonesia. These data can be used for evaluation of the status of the investigated species.
