Abstract

Clownfish (Amphiprion ocellaris) is one reef fish that can be used as ornamental fish saltwater aquarium. The fish has high economic value because the color is attractive. However, this time facing the difficulty found the seeds found in nature as a result of uncontrolled harvesting, especially in the northwest district of Simeulue. The purpose of this study is a way of domestication of clownfish in a population that is almost extinct (endangered) of wild life (natural habitat) into the cultivation environment to determine the viability of a clownfish by administering salinity 32, 30, 28 and 26 ppt performed for 60 the aquariums in a container measuring 60 cm (long), 40 cm (wide) and 40 cm (high). The results showed that administration of different salinity did not significantly affect survival (p>0.05), while the absolute growth rate and feed conversion showed significant results (p<0.05), the value range of the absolute growth rate was ± 0.0014 to 0.00444 grams of feed conversion has a value range of ± 1,311- 5.190 grams.

Abstract

This study aims to determine the effect of administration of activated charcoal, zeolite, and manganese greensand on survival Oreochromis niloticus. The experimental design used was a completely randomized design (CRD) with 4 treatments and 3 repetitions. The treatments are P1 = without administration (control), P2 = administration of activated charcoal 10 gr/l P3 = administration of Zeolite 10 gr/l and P4 = administration of manganese 10 gr/l. The parameter observed in this study was survival Oreochromis niloticus. The results showed that administration of activated charcoal, zeolites, and manganese greensand significantly affected the survival of Oreochromis niloticus. The best value is obtained at treatment P1; P2; and P3, each with the best average survival value of 96%; 91%; and 91%. The lowest cost incurred is the treatment P1 Rp. 66.200, - with SR 96% transportation.

Abstract

Saprolegnia sp fungi are freshwater mushrooms that live in freshwater environments and require water to grow and reproduce. Mushroom Saprolegnia is a major type of water fungus that is associated with fungal infections of fish and eggs that are in freshwater. Saprolegnia sp fungus is also called a cold water fungus because it spreads in cold water. Saprolegnia fungus growth in fish / egg bodies or suitable substrate is affected by water temperature. Saprolegnia sp attack causes clinical symptoms that are filled with white threads such as cotton grown in fish eggs. To overcome this problem needed a solution for the prevention of fungal infections one of them is by using anti-fungal herbs such as chicken shoot leaves (Tagetes erecta L). therefore this research needs to be done to control fungal infections Saprolegnia sp on tawes fish eggs. This study used a complete randomized design (RAL), each treatment was repeated three times, the treatment was: P0 = ppm, P1 = 400 ppm, P2 = 600 ppm, and P3 = 800 ppm. The results showed that the most effective extraction was found in treatment P1 with an average value of 14%.

Abstract

Indonesia has tropical marine waters rich in biodiversity. One of the organisms living in Indonesian coastal waters is macroalgae. Algae is one of the marine natural resources of economic value and has an ecological role as a high producer in the food chain and spawning place of marine biota. types of macroalgae have many benefits, ecologically and economically for the community. The ecological benefits of macroalgae are to provide habitat for several types of marine life such as species of crustaceans, mollusca, echinoderms, fish or other small algae. The economic value of macroalgae can be used as food, industrial raw materials, and materials for laboratories such as wet preserved materials, media materials for bacterial and fungal breeding to produce antibiotics, and there are also macroalgal types used as medicines. This study aims to identify and inventory the types of macroalgae in Lhok Bubon waters. The research method used is survey method, by identifying macroalga and inventory of macroalga contained in research location. The results of identification of macroalgae in Lhok Bubon waters are Caulerpa racemosa, Chaetomorpha anteninna, Halimeda micronesica, Boegesenia forbesi, Cladhopora hespetica,  Halimeda discoidea, Chaetomorpha sp, Sargasum sp., Sargasum natans, Padina australis, Turbinaria ornata,  Canistrocaptus crispatus, Asparagopsis taxiformis, Galaxaura filamentosa,  dan Halymenia durvillei.

Abstract

Eel (Anguilla sp) is an export commodity from fisheries and high economic value . Indonesia has high potency of eel elver and glass ell, but until now its use for aquaculture is still very low. The aims of this study were to fishculture system with enviromental approach and management of feeding the eel growth in container cultivation as domestication. This study was conducted from March to May 2016. The experimental design used was a completely randomized design  with three different feeding treatments and each treatment was repeated three times. The eel was used for this studied Anguilla sp. of stadia elver with an average weight 0,5 gram/fish. The results showed that different feeding treatment giving significantly affect all parameters. The best feeding was mixture of feed pellets and tubifex with a survival of 73.92 %, growth rate of 0.030 g, the biomass growth rate of 9.07 g/day, and the feed conversion of 1.32.

Abstract

Tawes (Puntius javanicus) is one of the freshwater fish species that has economic value in Aceh. One of the obstacle in tawes fish breeding is Saprolegnia sp. fungus that attacks tawes fish eggs. The necessary solutions  was needed to resolve fungal infection by using Tagetes erecta L. Therefore this research was very important to control fungal infections on fish eggs Saprolegnia sp.. This study used Randomized Complete Design with four treatments and three raplications for each treatments. The treatment in this study namely P0 = P1 = ppm, 40 ppm, P2 = 50 ppm, P3 = 60 ppm, and P4 = 70 ppm. The parameters observed in this research is the prevalence of eggs hatchability rate, eggs growth and water quality. The results of this study showed that the highest value of tawes eggs hatchability (prevalence) found in treatment 3 (P3 = 60 ppm) was 53.33% and the lowest value was present in control treatment (P0 = 0 ppm) was 36.66%. The reasults of eggs hatchability rate (HR) show the highest values found in treatment 2 (P2 = 50 ppm) of 95.66% and the lowest value is present on the control (P0 = 0 ppm) of 45.66%. On the egg development stage shows that there is a embryogenesis process starts from cleavage, morula, blastula, gastrula, organogenesis to become larvae. Water quality during the research shows that water temperature range were 29.2-30oC, and DO water range were 3.6-4.8 mg/l.
