Abstract

The aim of the study was to know the effect of soy sauce waste as substitution of fish meal in diet on the growth and dietary nutrient digestibility of juvenile tiger grouper (Epinephelus fuscoguttatus). The experiment used completely random design (CRD) with six treatments and three triplicates. The initial body weight of juvenile tiger grouper was 4.03 g and total length of 5-7 cm reared in 18 polycarbonate tanks with each 30 liter volume. Each of tanks was equipped with aeration and flow through water system. Six formulated diet with dry pellet form containing different level of soy sauce waste as substitution of fish meal, i.e., 0%, 7%, 14%, 21%, 28% and 28% added 0.15% methionine amino acid were teste. The result showed that the utilization of soy sauce waste as substitution fish meal influenced absolute growth, specific growth rate, feed conversion ratio and protein retention (P<0.05), but not significantly different (P>0.05) on survival rate of juvenile tiger grouper. Dietary nutrient digestibility (protein) obtained 98.05- 99.69%. Dietary nutrient digestibility decreased with utilization of soy sauce waste in diet. These experiments concluded that the utilization of soy sauce waste as substitution of fish meal could be used until optimal limit 21%, while the substitution of 28% can’t used for diet formulation for tiger grouper (Epinephelus fuscoguttatus).

Abstract

Catfish (Clarias gariepinus) was cultured with an aquatic plant, water hyacinth/eceng gondok  (Eichornia crassipes), kangkung air (Ipomea aquatica) or kapu-kapu (Pistia stratiotes) in concrete ponds, for 3 months. Catfish cultured without aquatic plant was used as a control. The experiment was carried out to evaluate the survival rate as well as the growth of fish and aquatic plants.The survival rates of catfish cultured with I. aquatica, E. crassipes, and P. stratiotes were 76, 87, and 98%, respectively. In addition the survival rate of catfish cultured without any aquatic plant was 93%. The weight gain of catfish was 14,1-16,2 kg per pond. Whereas, the total weight gains of aquatic plant were 37,0,  27,7 and 7,7 kg per pond for E. crassipes, P. stratiotes, and I. aquatica,. Respectively. Dissolved oxygen, and the concentrations of NH3, NH4+ and PO43- in water with aquatic plants were higher than that of in water without aquatic plant. However, the concentration of CO2 was higher in water with aquatic plant.

Abstract

This experiment was conducted to determine the dietary n-3 fatty acid requirement for reproduction of broodstock zebrafish, Brachydanio rerio. Three isonitrogenous (39% crude protein) and isocaloric (3,260 kcal digestible energy/kg diet) practical diets, namely diets A, B, and C, with different levels of fatty acids were fed to zebrafish broodstock. The broodstock were cultivated in aquaria. Diet A contained low dosage of n-3 fatty acids (0.4%) and 2% n-6 fatty acids, while diets B and C contained 2% n-6 fatty acids, combined respectively with 1% and 1.5% n-3 fatty acids. Fish were fed ad satiation for 60 days using these diets. During feeding periode, gonade maturation stages were examined. The n-3 and n-6 fatty acids affected fecundity, fertilization rate, and hatching rate. On the other hand, fish fed on diets A, B, or C did not show any significance differences in the gonade somatic index and total Survival Rate (SR) of larvae produced. Fish fed on diet B produced the highest fecundity (616 eggs/g of fish), fertilization rate (94.6%), and hatching rate (93.8%). The total lipid content of eggs were significant, ranging from B (29.7%), C (23.7%), and A (16.1%). At a dosage of 2% n-6 fatty acids, zebrafish require 1% of dietary n-3 fatty acids in the diet for reproduction. Excess dosage of n-3 fatty acid in the diet adversely affected fecundity, fertilization rate, and hatching rate.

Abstract

The industrial and domestic waste containing heavy metal contaminate river and the sea. Through bioacumulation process, contaminant was absorbed by aquatic organisms such as fish, shellfish and shrimp. The aim of this research was to identify the influence of fish and shellfish consumption on lead concentration in blood of people who consumed fish and shellfish. Human blood samples were taken as specimens in this research. Maximum level of lead permitted by World Health Organization (WHO) in human blood is 80 mg/100 ml. Samples of human blood, fish, shellfish, and sea water were taken from two locations of fisher groups, i.e. from Sukolilo subdistrict, district of Kenjeran, Surabaya, and from Lobuk village, district of Sumenep, Madura. Lead concentration in the samples were analyzed by AAS (Atomic Absorbent Spectrophotometer) method. Data were subjected for t-test analysis. Results showed that lead concentration in women blood living in Sukolilo (Kenjeran,Surabaya) and Labuk village (Sumenep, Madura) were significantly different, while the mean level of lead in human blood in Sukolilo was higher than that in Labuk village. In Sukolilo, consumption of fish and shellfish had a major contribution to the level of lead in human blood.

Abstract

The aims of this research were to know the state of small pelagic fishery and social economic aspect of resources exploitation. To examine these issues, the research combined survey and descriptive analytic methods. Gordon-Schaefer model was applied to analyze the state of fishery and analytical descriptive to explained the relationship of the phenomena's. Data collection was based on indepth interview and recording of District Fishery Service's. Samll pelagic fisheries that been analyzed were anchovies (Stolephorus sp.), squids (Loligo sp.), and mackerels (Rastrelliger sp.).There are two main problems of fisheries in the area, firstly, the conflict on coastal zone between marine capture fisheries and mariculture. The second one is the intensive exploitation of fisheries resources. Pelagic fisheries at Sape Bay have been exploited above maximum TAC mainly 80% of MSY. MSY of anchovies (Stolephorus sp.) reached 2324,9 ton at number of effort 56534 trip and MEY 2172,3 ton at number of effort 42144 trips. MSY of squids (Loligo sp.) is 455,0 ton at number of effort 12183 trip and MEY 449,0 ton at number of effort 10780 trips equal to Bagan Perahu  trips. The model was not applicable to predict the MSY and MEY of mackerels (Rastrelliger sp.). The continuing increase of effort will depleted the stock and decreased economic rent. In addition, the increasing of competition on fishing ground with pearl culture, have resulted fishermen stress. The integrated policy and management are needed to solve these problems and to avoid social riots.

Abstract

Cryopreservation technology of fish sperm has been developed to prolong gamete viability. Combination of two extenders (ringer or glucose) and two cryoprotectans (DMSO or methanol) on three concentrations have studied to sperm cryopreservation of nilem. Nilem fish brooder induced by GnRHa and domperidone combination. Sperm was diluted in extender at the ratio of 1:9 then cryoprotectant was added at 5%, 10% or 15% (v/v) concentrations. Samples were stored in 0,5 mL straws, equilibrated at temperature 4 – 5 oC for 20 minutes, vaporized at 3 cm above surface liquid nitrogen for 3 minutes and then plunged into liquid nitrogen, where they were stored for 1 weeks. Sperm was thawed at temperature 39 – 40 oC for 10 – 15 sec. and was used to fertilize 100 – 200 eggs per straw. The highest percentage of post-thawed sperm was combination ringer and DMSO 10% (87.50 ± 5.00%) and the lowest was combination ringer and methanol 5% (23.75 ± 4.79%). The highest hatching rate fertilized by post-thawed sperm was combination ringer and DMSO 15% (54.98 ± 28.61%) and the lowest was combination glucose and DMSO 15% (6.54 ± 3.32%). The study proven combination of ringer extender and DMSO cryoprotectant effective for cryopreservation of Indonesian silver sharkminnow fish sperm. Therefore, fish sperm cryopreservation with nilem as a representative model could be developed to extend on other Cyprinidae.
