Abstract

Intensification of shrimp farming has led to problems of water quality and development of pathogenic bacteria. The excess feed and fecal deposited in the bottom of the pond undergo ammonification and result in excess of ammonia formation in pond water and sediment. The purposes of this research was to investigate the impact nitrifying bacteria application on the controlling of pathogenic Vibrio sp. bacteria and toxic nitrogen gasses. Twelve (12) transparent glass bottles (effective volume of 3 L) were used in this research. Tested probiotic was purchased in free market and producer claims to contain Nitrosomonas sp., Nitrosococcus sp., Nitrobacter sp., Bacillus sp., Aerobacter sp., and Pseudomonas sp. The tested media was sea water containing Vibrio sp., TAN, NO2 and NO3 of 54.07 ± 2.93 mg/L; 6.33 ± 0.17 mg/L; 2.43 ± 0.04 mg/L; and 0.46 ± 0.01 mg/L respectively. The treatment of probiotic was 0 mg/L as a control; 0.1 mg/L; 0.2 mg/L; and 0.4 mg/L with 3 replications. In regard to concentration of Vibrio sp., NH3 and NO2 gasses, treatment doses of 0.1 mg/L (A) resulted a save level within 4 days after treatment, but to more secure in the practical work for shrimp farm, the doses of 0.2 mg/L (B) is suggested.

Abstract

Pronghorn spiny lobster (Panulirus penicillatus) is one of the dominant lobsters and has high economic value. The fishing activities are conducted continuously and put aside the preservation of these resources. This study purposed to analyze the population dynamics of pronghorn spiny lobster (Panulirus penicillatus) in Pelabuhanratu Bay, Sukabumi, West Java. The data were collected from January until December 2016 with samples from local fisherman. Lobsters were measured carapace length and total weight. Data analysis included the relationship between length and weight, growth parameters, recruitment patterns, mortality, exploitation rate, length at first maturity or incubating eggs (Lr), and length for first capture (Lc). Panulirus penicillatus from the Palabuhanratu Bay has growth pattern of a negative allometric in both males and females. The asymptotic carapace length (CL∞) of males is higher than females while the growth coefficient (K) of males is lower than females. The peak recruitment for males is expected to be in April and July, while for females in May and August. The total mortality rate of males is higher than the natural mortality rate and vice versa for females. The male lobsters have occurred overexploitation, while females have not occurred overexploitation. The female lobsters have an Lr <Lc value which indicates that the female lobsters are caught after incubating the eggs.

Abstract

Reef fish in Spelman strait, Indonesia, is one of the fishery resources of considerable economic value. Unfortunately, there is still the use of unfriendly resources equipment (destructive fishing) that cause potential social problems. In this study, all components of the EAFM (Ecosystem Approach to Fisheries Management) composed of 6 domains, namely (1) fish stocks, (2) environment and ecosystem, (3) fishing techniques, (4) culture, (5) social, and (6) institutional are analyzed combining with MDS (Multidimensional Scaling). The main aim of this research is to find out the root solution for managing coral reefs in the coastal waters of Spelman Strait. The sustainability status review in the fishery resource domain, the environment and ecosystem domain, the fishery technique domain, the social domain, and the economic domain were respectively were 87.69, 88.17, 51.22, 51.61, and 72.67 which were in the category sustainable. Meanwhile, the sustainability status review in the institutional domain was 42.15, which was in the category of less sustainable. Institutions are the primary base for reef fishery protection in the Spelman Strait.
