Abstract

In intensive fi sh farming, feed costs can reach up to 70% of the total cost production, so that its effi ciency needs to be improved. The aims of this study were to improve fi sh growth rate and feed effi ciency for rabbit fi sh grow-out through supplementation of crude papain enzyme in the feed. Test fi sh were juvenile of rabbitfi sh, Siganus guttatus, with average initial weight of 40±3.5 g. Fish were stocked in 12 of 1×1×2 m3 fl oating net cages with density of 16 fi sh/cage. As dietary treatments were different dosages of crude papain enzyme namely (A) 0%, (B) 0.0125%, (C) 0.025%, and (D) 0.050%. The rabbitfi sh were fed to satiation in the morning and afternoon for 120 days. The results showed that specifi c growth rate, survival rate of the fi sh, feed effi ciency, protein effi ciency ratio, and the level of feed intake were not signifi cantly different (P>0.05) among treatments. However, there was a tendency that increasing of supplementation level of crude papain enzyme in diets, fi sh growth rate, feed effi ciency, and protein effi ciency ratio also increased.

Abstract

This research was conducted to isolate, identify, and characterize pathogenic Vibrio spp., causative agents of vibriosis in grouper at Brackishwater Aquaculture Development Center (BADC), Situbondo. Twenty-nine isolates were isolated from wound, gills, eyes, liver, and ren of grouper with vibriosis on Thiosulphate Citrate Bile Sucrose Agar (TCBSA) medium. Koch Postulate Test was conducted to determine pathogenic Vibrio spp., by intraperitoneal injection to humpback grouper (Cromileptes altivelis) (9-10 cm of total length) at 106 cells/fish in triplicates. Results indicated that the pathogenic Vibrio spp., causative agents of vibriosis in grouper at BADC, Situbondo were identified to be V. alginolyticus, V. anguillarum, V. metchnikovii, V. vulnificus, V. fluvialis, V. furnisii, and V. parahaemolyticus. Infection of the pathogenic Vibrio spp. caused acute mortality within 17-46 hours with specific disease signs like haemorhagic on fins (pinnae pectorales, pinnae abdominales, pinna analis) and also on the body. These results suggested that vibriosis should be monitored and controlled properly and quickly.

Abstract

The aims of this research were to know the history and development of fisheries activity and its contribution to coastal community welfare at South Coast of Yogyakarta Special Territory Province. To examine these issues the research was conducted by combined survey and descriptive analytic methods. Fisheries in area could be categorized as new activity and historically community does not have a high dependency on marine capture fisheries. Fishers were  farmers who become fisherman due to several reasons such as limitation of land and lack of other job opportunity. Since the activity began in the end of 1970’s at Baron, marine capture fisheries have altered income sources, improve community houses, and attracted young people as well as provide productivity activity for rural women. In the recent time, marine capture fishery has dispersed to all of Yogyakarta South Coastal area at 19 fish-landing places with vary intensity of resources exploitation. Marine capture fisheries are still limited in the coastal zone. Although CPUE tend to increase, the activity should be extended to province management zone and ZEEI. The integrated policy and management are needed to solve these problems and to avoid the tragedy of the commons.
