Abstract

The objective of this study was to determine the diversity and abundance of krustaseans in the mangrove area of Jangkaran Village, Temon District, Kulon Progo Regency. Sampling was done bi-weekly from October 2016 to February 2017 on six stations defined by ecological character. Krustasean sampling was done using cest net, trap net and hand picking along the river with the extent of each collection station about 10 m2. The captured krustasean samples were cleaned, stored in ice-cooled boxes and transported to the laboratories to be identified and grouped according to species, then measured by carapace length and individual weight. Observation of aquatic environment was done by measuring temperature, brightness, water depth, current velocity, pH, salinity, dissolved oxygen, and substrate type. The results of the observation obtained 1 order, 7 families, and 26 species. The family krustaseans found were Coenobitidae, Diogenidae, Grapsidae, Ocypodidae, Palaemonoidae, Penaeidae, and Portunidae. The most dominant species of krustaseans were white shrimp (Penaeus merguiensis) as much as 25.06%, hermit crab (Clibanarius sp.) as much as 10.85%, and Uca annulipes as much as 10.59%. The fewest species of krustaseans found were Varuna yui of 0.13% and Ocypode sp. as much as 0.26%. The abundance value was 25.4 ind / m2, indices of diversity 2.60, richess index 0.87 and index of dominance 0.18.

Abstract

The purpose of this study was to describe the asymmetric potential possessed by the pectoral fin organ Clarias gariepinus catfish originating from maintenance in aquaculture ponds. Individuals who do not grow a pair of pectoral fins are mated to a normal pectoral finned individual to obtain fish seed (F1). The study was conducted from January to April 2017 at the Reproductive Laboratory of Aquaculture Studies Program Department of Water Resources Management Faculty of Fisheries and Marine Science Universitas Brawijaya Malang. The observed variables are asymmetric score and Asymmetric Fluctuation Index (FA). The number of lefts and right pectoral fin radius, as well as abnormal F1 percentage, were analyzed. Long-weight relationship was analyzed by linear regression and PT/BB ratio. The conclusions using Mann Whitney-U Test (α = 0.01). The results showed that the population of F1 from the parent fish of the non-pectoral mortal differs very significantly with the controls on the asymmetry score variables (13.63±29.88), FA (1.25±2.05), the average number of pectoral left fins (8.95±3.22) - right fin (9.10±1.89), and the ratio of PT/BB (1.57±0.61) with a long-weighted relationship based on the equation y = 3.25x-2.04. Based on the results of this study it is concluded that the catfish Afrika Clarias gariepinus with perfect loss pectoral fin has the potency to generate asymmetrical characters to its generation and rising FA that is influenced by the hybridization or crosses.

Abstract

This research aims to know the influence of the thickness of catfish culture waste on silk worm (Tubifex sp.) biomass. The research was conducted with culturing Tubifex sp. in different thickness media of the waste as treatments. The treatments consist of the waste 2, 4, 8 and 12 cm thickness of medium with 6 cm depth. The stock densities 150 g/m3 with average weight 0.0062+0.00032 g. The parameter that analyzed is biomass and population of Tubifex sp.. Data analyzed by analysis of variance and posthoc test is Duncan’s Multiple Range Test. The result shows that diversification of medium thickness gives the real influence (P<0.05) to Tubifex sp. biomass. The highest biomass 1745.14±143.77 g/m3 and population 233,848.46±19265.61 ind./m3 on the treatment with 8 cm thickness. The relationship between treatment and biomass production of Tubifex sp. is quadratic relationship with y = -30.405x2 + 552.18x – 823.55. The optimum thickness of medium that results maximum biomass production is 9.1 cm.

Abstract

Maluku is one of the archipelago province in Indonesia that has small pelagic fish resources with widespread distribution, such as lompa (Thryssa baelama Forsskål). One of lompa habitat in Mollucas is in Apui coastal areas. The presence of lompa depends on physical and chemical parameters in the waters. This study aims to determine the influence of physical and chemical parameters on the presence of lompa in Apui coastal area Central Mollucas. This study was conducted in June - July 2015. This research is ex-post facto using the value of Environmental Water Quality Index which refers to US-National Sanitation Foundation-Water Quality Index (NSF-WQI). Physical and chemical parameters measured include temperature, velocity, depth, brightness, salinity, pH and dissolved oxygen. The results of calculations with the Indeks Mutu Lingkungan Perairan (IMLP) are 95.61; 92,15; 88.61; 96,37; 93,76; 79.57. And the results of lompa fishing were 181, 162, 205, 173, 184, and 97 respectively. The research conclusion is that the Apui coastal areas are in good condition and potential as lompa habitat.

Abstract

Histamine toxicity can be occurred after consumsing decomposing fish (pindang). The community (fishermen) perform different handling techniques on raw materials of pindang to slow down the decomposition process. This research is aimed to know the influence of various techniques of handling fish on the quality of raw materials of pindang. This research used completely randomized design with single factor. This study compared various methods of fish handling commonly used by community (fisherman in Kusamba village) to maintain the quality of raw materials of pindang, such as: kept on room temperature (technique A), add 1 kilogram crushed ice for 4 kilogram fishes (technique B), add 10% salt (technique C), and combination of technique B and C (ice and fish combination 1:8 plus 5% salt as technique D). Diversity analysis show a significant influence of different techniques of fish handling on the quality of raw material of pindang (p value <0.05). Addition of crushed ice show the best quality result among fish handling technique with histamine levels 11.30 mgN%, moisture content 74.53%, TVB 20.19 mgN%, salt 0.32%, bacteria 13 x 101 colonies / g, and negative coliform. Organoleptic assessment for B techniques also show the best result with visibility score 8.0 (bright, strong, and thin scale), eye 7.7 (convex, slightly foggy cornea, slightly faint pupil), odor 7.8 (soft odor), and texture 7.8 (elastic).

Abstract

Human Chorionic Gonadotropin (hCG) and Pregnant Mare Serum Gonadotropin (PMSG) hormone is a product that contains the hormone Folicle Stimulating Hormone (FSH) and Litiunizing hormone (LH) that play a role in regulating the development gonad process of fish. This research determine to effect hCG and PMSG hormone induction and find out the best treatment in the induction on gonad maturation of Silver pompano fish. This research used three treatments: control (NaCl), hormone hCG 20 IU.kg-1 and PMSG 20 IU.kg-1 fish body weight. Containers used in the maintenance of fish in the form of Floating Net Cage (KJA) with size 3x3x3 m. The best research result is 20 IU PMSG treatment with GSI value equal to 0.6%, HSI equal to 1.25%, maturity level of gonad reaches TKG III and histologically progress reach secondary oocyte and primary oocyte. The conclusion of this research is hCG and PMSG hormone induction effect on gonad maturation Silver pompano fish for 4 weeks compared to control treatment. The best hormone treatment is PMSG hormone treatment with a dose of 20 IU. Kg-1 fish body weight.
