dc.description.abstract | Degradation of ecosystem and depleting fisheries resources together lead to poverty and marginalisation of traditional f ishermen depending on open water bodies. Challenges related to depleting fish wealth of Ashtamudi lake has been reported to affect livelihood of f ishermen using traditional methods of f ishing. A pre-growout culture of Asian seabass was initiated in participation with traditional Chinese dip net f ishermen in order to assess feasibility of seabass culture in low volume net cages in Asthamudi lake, Kollam District, Kerala. Fingerlings of Asian seabass (avg wt., 8 g) produced at fish hatchery, Muttukadu experimental station, CIBA, were transported in oxygen packing (5 nos/5 l) involving a transport duration of 18 h. Hundred numbers of seabass were stocked in a low volume net cage of dimensions, 1.5 x 1.5x 1.5 m and mesh size, 22 mm. Fish were initially fed twice a day @ 20% bodyweight initially approximately on trash f ish obtained from the Chinese dip net owned by the f isherman. Periodic samplings were conducted to assess growth potential and survival of the f ish in the small volume cage model. Size based segregation into 2 groups was done at the end of 60 days and the f ish were stocked into two separate cages of equal volume, cage 1 was stocked with f ish above 70 g (40 numbers) and cage 2 with f ish below 70 g (20 numbers). Small seabass below 15 g were separated. At the end of the 90 day pre-growout culture, the fish attained a f inal average body weight of 182.07±10.94 g, with a specif ic growth rate of 3.38±0.08 % day-1, an avg. weight gain percentage of 2175.8±136.7 and an overall survival of 63 %. The average body weight of cage 1 and 2 were 214.04±8.47 g and 95.75±8.75 g respectively. The results showed the feasibility of carrying out pre-growout culture of seabass in low volume net cages and highlights the prospects of adoption of small scale cage culture of Asian seabass as a livelihood option for augmenting the income of the traditional f isherfolk depending on the open water bodies. | en_US |
