Short term culture of wild caught juvenile rabbit fishes (Siganus javus) in open sea cages at Palk Bay

چکیده
Objectives: The main objective of the study was to collect and rear unmarketable, small sized S.javus which is mostly rejected by traditional fisherman. During fishing activities, under ranging in sizes from 25 40 kg (< 30-40 % total catch/day) being captured. Due very low marketable value these fishes (<250 g) get rejected. Therefore, we utilized this as an economically viable option for utilization seeds rearing until they reach necessary size. Methods: Undersized juveniles (12-16 cm, -55 were collected nearby Olaikuda village,Rameshwaram using traps made bamboo odai tree bark (Acacia planifrons). stocked sea cages fed with locally formulated plant based feed containing 28-32 crude protein. Findings: Harvesting successfully done after 140 days 90 survival. average growth rate achieved 2.5 g /day FCR 2.01. This resulted harvest size 400 g/fish its initial stoking 50 attracted market Rs. 150/kg. Novelty: Till date, no attempts commercialize such harvesting techniques species Siganus javus pilot scale India (Except James, 1984). Keywords: Rabbit fish; javus; cage culture; rabbit fish Siganidae

Rabbitfish is economically valuable teleost species which lives in shallow coastal waters. Two species of rabbit fish have been recognized in southern sea of Iran (Persian gulf) as namely Siganus sutor and Siganus javus. In the current study, in order to investigate the histology of the annular ligament of the S. javus’ eye, the prepared sections of the eyes of twelve healthy specimens were stu...

Short-term production plans are the basis for operational mine production schedules. They concentrate on making long-term mine plans operationally feasible. Furthermore, some variables such as ore grade and tonnage govern mine production systems and cause uncertainty in the supply of raw materials to the mills. Due to the quality variation of material, short-term production optimization is an u...
