Abstract

The purpose of the research were to determine the toxicity and antimicrobial activity of ethanolic extract of sponges collected from Tabuhan Island, Banyuwangi and Menjangan Island, West Bali. Extracts were made by maceration of the sponge samples for 3 x 24 hours. The toxicity test was carried out by Brine Shrimp Lethality Test (BST) with 48 hours-old Artemia sp. The effect of ethanolic extract was identified by determining the mortality of Artemia sp. and LC50 of each extract was analyzed by using probit analysis. Antimicrobial activity was tested by agar diffusion method. The result showed that several ethanolic extracts exhibited toxicity to Artemia sp. The toxicity test showed that extract of sponge code B43 was the most toxic with the LC50 of 8.4 µg/ml. Antimicrobial activity test exhibited that ethanolic extract of sponge with code numbers B2, B57, B61 dan W5 were active against Candida ablicans, while the axtracts of sponge with code numbers B9, B35, B47, B51 (Liosina sp.), B57, B61, B63 and W11 were active against Staphylococcus aureus. One ethanolic extract from sponge with code number B57 exibited activity against Eschericia coli.

Abstract

The objective of the experiment was to know the effect of vitamin C on gonadal development of giant freshwater prawn (Macrobrachium rosenbergii) broodstock. Female broodstock of 30-60 g and male broodstock of 40-70 g average body weight were used in this experiment. The broodstock were fed with different dose of vitamin C in feed as 0; 0.05; 0.10; and 0.15% at 3-4% of biomass weight per day for 3 months. Gonado Somatic Index (GSI) value obtained from the diet with 0.15% of vitamin C was significantly different from others (P0.05). The supplementation of vitamin C in the diet of giant freshwater prawn broodstock is important for gonadal development.

Abstract

This study was aimed to investigate fish farmer’s attitude on production risk of Epinephelus fuscoguttatus growing in floating net cages, and to evaluate the impact of input usage on the production risk. The production risk explicitly assumed, reflected in the variability of E. fuscoguttatus production.The study used the case of fish farmer’s production of grouper growth out in floating net cages in Lampung Gulf, Lampung Province as an analysis unit. The respondent of fish farmers were obtained by census method.The analysis result suggested that the fish farmers were risk-averters toward fish seed, fish feed and human labor input. It also appeared that fish seed and fish feed were risk-inducing inputs while the amount of human labour was a risk-reducing input. Fish farmer’s attitude that avoid of the usage of human labour, more considered by decreased effort efficiency which was affected by increasing the amount of human labor whereas production level tend to remained or lower. However by the level domination of adequate E. fuscoguttatus culture technique which owned by the human labour, the usage of human labor could be act as “risk-reducing”.

Abstract

The aims of this research were to evaluate the eficacy of intra- and extracellular products vaccines of Aeromonas hydrophila to control Motile Aeromonas Septicemia (MAS) in catfish (Clarias sp.). Catfish with 10-13 cm of total length were used for the experiment with three treatments in five replicates. The treatments were vaccinations with (1) A: intracellular product of A. hydrophila; (2) B: extracellular product of A. hydrophila; (3) without vaccination (control). Vaccination was conducted by intramuscular injection of 5 µg protein/fish (each fish was injected with 0.1 ml of vaccine). Booster was conducted one week after vaccination. The challenge test was conducted two weeks after booster. The results showed that the survival rate, Relative Percent Survival (RPS), and antibody titer of A treatment was significantly different (PA. hydrophila (A treatment) reached 85.33 and 82.26%, respectively. The highest antibody titer was 1843.2 which was obtained by the A treatment. The results suggested that intracellular product vaccine of A. hydrophila was more effective than extracellular product vaccine.

Abstract

Genetic variations of marble groupers, Epinephelus polypekhadion were evaluated to know genetic performance of fish to support fish seed production. Fifty fish samples from three locations i.e. West Nusa Tenggara, South Sulawesi and East Java were collected for analysis. Genetic analysis has been examined through allozyme electrophoresis by using 11 enzymes (ADH, GPI, SDH, IDH, LDH, ME, PGM, 6PGD, MPI, SP, EST). The result showed that 16 loci were detected, and three of them were polymorphism enzymes namely Isocitric dehydrogenase (IDH*), Glucose Phosphate Isomerase (GPI-1*) and Esterase (EST-2*). One locus (EST-2) was polymorphic in the East Java and West Nusa Tenggara populations and three loci (EST-2, GPI-1 and IDH) were polymorphic in the South Sulawesi population. The heterozygosity ranged from 0.007 to 0.034. Rogers genetic distance between population pairs were ranged from 0.005 to 0.012 (average = 0.009). Differences between genetic populations were significant (P<0.05). East Java and West Nusa Tenggara populations have same gene pool.

Abstract

This research aimed to understand the adoption level of insulation palka for handling fresh fish, and the relationship between internal-external characteristics of fisherman with technological adoption level. The research was located in Pelabuhanratu, Sukabumi which was one of the locations for the introduction of insulation palka by Fisheries Research and Development Centre. Samples were collected by purposive sampling method, with fisherman using insulation palka to handle fresh fish as respondent. Data were analysed by descriptive analysis and non parametric (Spearman correlation) test. The result showed that fisherman in Pelabuhanratu had a high motivation to adopt insulation palka technology indicated by application of recommended technological packages. The relationship test indicated that formal education factor, family income, numbers of labours in family, reason of using insulation palka, cosmopolitan, interaction with extension agent and decision making type should be paid attention related to every effort to introduce the similar technology. Besides, external characteristics which should be paid attention were member of fisherman group, availability of infrastructure, enforcement of society leader, institution support, capital source, marketing, and culture value.

Abstract

Fisheries productivity is defined as a comparison of production to fishing effort.The Fishing effort can be the number of fishers, fishing boats or fishing gears. This paper was developed from analysis of Indonesia Fisheries Statistic data in the period of 1990-2001 at 9 regions of fishery management in Indonesia. It was assumed that the catch by fisherman in each region will be landed at the same region. The results showed that productivity level of fisherman was lowest at WPP-9 (Indian Ocean) with a value 1,2 ton per year (an average 100 kg per month per fisher). The highest productivity of fisherman reached 3.1 ton in 1999 at WPP-5 (Sulawesi Sea and Tomini Gulf). The productivity of fishing boat was ranged from 7.8 ton to 16.4 ton per year per fishing boat. Then the productivity of gear was from 5,0 ton per gear per year to 13,5 ton per gear per year. From this result, it can be predicted that the distribution of fishing gear, fishing boat and fisherman in 9-WPP was not equally proportional. For sustainability life of the fisheries, it need a policy which may increase to economic benefit of fisherman and fishing activity.

Abstract

This experiment was conducted to determine the effect of dietary single cell protein as substitution for fish meal in fish diets. Five isonitrogenous (38% crude protein) and isocaloric (3,040 kcal digestible energy/kg diet) practical diets, namely diets A, B, C, D and E with different levels of single cell protein were fed to juvenile common carp (Cyprinus carpio). Twenty juveniles/aquarium with an initial weight of 1.20±0.11 g per individual were used in this experiment. Fish were cultivated in aquarium of 60 l capacity under standardized conditions at 26±10 C. The aquaria assigned to 5 treatments were arranged in triplicates. Diet A contained low dosage of single cell protein (0 g /100 g diet), while diets B (9.8 g /100 g diet), C (19.5 g /100 g diet), D (29.3 g /100 g diet), and diet E (39.5 g /100 g diet ), combined respectively with 39.5 g fish meal/100 g diet (diet A), 29.3 g fish meal/100 g (diet B), 19.5 g fish meal/100 g diet (diet C), 9.8 g fish meal/100 g diet (diet D), and 0 g fish meal/100 g diet (diet E). Fish were fed ad satiation for 45 days using these diets. The dietary with different level of single cell protein affected growth rate and feed efficiency. Fish fed on diet 39.5 g fish meal/100 g (diet A) produced the highest growth rate (1.15±0.267%) and feed efficiency (61.68±9.89%). Growth rate and feed efficiency decreased synchronously with increases in single cell protein in the fish diets. Lysine and tryptophan were higher in single cell protein than in fish meal; whereas arginine, histidine, isoleucine, leucine, methionine, phenylalainine, threonine and valine were lower in single cell protein. On the other hand, fish fed on experimental diets did not show any significance differences in the survival rate.
