Domestication is the process of taming fish from the wild to the aquaculture environment. There are 3 stages of the domestication process, namely: taming/adapting to the aquaculture environment, seeking fish to grow, and seeking fish to reproduce. Bileh fish can already be adapted to aquaculture containers, which is the first stage of the domestication process. However, information on suitable feed for fish growth is still limited. The aim of this study was to determine the effect of different feeding on the growth of bileh fish reared in controlled containers. The research method was experimental and used a completely randomized design (CRD), which consisted of 4 treatments (P) with 3 replications. The treatments given were artificial feed (P1), artemia (P2), rotifer (P3) and daphnia (P4). The research phase included preparation of containers, collection of bileh fish, experimental feed, maintenance, and data collection. Parameters taken and evaluated included: specific growth rate (SGR), absolute length growth (ALG), and survival rate (SR). The data were processed and analyzed with statistics (Anova). The results of statistical analysis showed that feed treatment had a significant effect on SGR (P<0.05), but had no significant effect on ALG and SR (P>0.05). The best treatment was P1 (artificial feeding) with an SGR value of 0.91%/day, ALG of 1.03 cm and SR of 100%.
Natural feed is one of the inputs that is needed during the rearing phase of fish larvae, especially when the york content has been completely absorbed by the fish's body. There are many types of natural food commonly used by marine fish hatcheries, both phytoplankton and zooplankton. Rotifera (Brachionus rotundiformis) is one of the zooplankton that can be used as natural food for fish larvae. This study aims to determine the effect of fermented tuna and rag roti on the growth performance of rotifers. This research was conducted in November - December 2021 at the Fish Seed Center (BBIP) Busung Indah, Simeulue Regency. The study was conducted experimentally using a completely randomized design (RAL) with four treatment levels and three repetitions. The results showed that different fermented tuna and baker's yeast on culture media had a significant effect on population density and growth rate of Rotifera significantly (P<0.05). Treatment (P4) 8 g of fermented fish added yeast 0.60 g was significantly different from the control treatment (P0), treatment (P1), treatment (P2), but not significantly different from the treatment (P3) tuna 8 g added bread yeast 0.45 g. The results of this study showed that the administration of fermented tuna and baker's yeast at a dose of 8 g and baker's yeast 0.60 g had a positive impact on the growth performance of rotifers, with an average of 196 ind/mL/day.
Disease infection in fish farming causes a decrease in production yields and crop failure. On the other hand, the decline in production and crop failure is also due to the lack of knowledge and skills of farmers in prevention and treatment. Treatment using chemical drugs continuously causes resistant fungi / bacteria so that it is difficult to eradicate. The solution offered to solve partner problems is to provide information on fish health management and the use of natural medicine. Implementation stages include: program preparation, program implementation, monitoring and evaluation, workshops and reporting. The results of this service show that fish farmers get increased knowledge about fish health management and the use of herbal medicine.
Simeulue Regency is surrounded by small islands rich in diverse fish resources, namely dogtooth tuna. The interaction (reciprocity) between groups of organisms and their environment plays an important role in ecological systems. The determination of ecological status can be used to monitor, manage, and sustain waters in tuna fishing areas. Fishing activities will affect environmental changes that will impact marine biota's sustainability, existence, and diversity. This study aimed to analyze the ecological sustainability status of tuna fishing areas in East Simeulue waters. The research was conducted in May-July 2021. The method used in this research was observing and measuring the characteristics of the aquatic environment and conducting interviews. The attributes seen include the condition of the aquatic environment, conservation of pelagic resources, fishing activities, utilization of pelagic resources, environmental carrying capacity, type of fishing gear, the volume of fishing gear, level of suitability for fishing. The sustainability status of the ecological dimension obtained a value of 79.74. The results obtained are classified as well sustainable.
