Abstract

Transportation of fish seeds is the best way to move fish seeds from farmers to buyers. Proper transportation of live tilapia fish can ensure that the fish remain alive, healthy and fresh until their destination. The aim of this research is to determine the effect of density and size on fish seed catch in tilapia seed transport and to determine the interaction between density and size on tilapia seed catch in semi-open transport. Research location: Transportation was carried out from the seed source at the tilapia hatchery business in Patas Village, Gerokgak District, Buleleng Regency and ended at the Mina Anakan Jepun Fish Cultivator Group, Bebetin Village, Sawan District, Buleleng Regency, Patas, Gerokgak District, Buleleng Regency, Bali. This research used a Completely Randomized Design (CRD) with a factorial pattern with 2 factors consisting of Factor 1, namely fish density consisting of 3 levels, namely 50 fish/liter, 75 fish/liter, and 100 fish/liter. Factor 2 is the size of the fish which consists of 3 levels, namely 5-6 cm, 7-8 cm, 9-10 cm. Based on the results of treatment research, the density of fish numbers and fish size showed a very significant influence (P<0.01) on the survival rate of tilapia fry during semi-open transportation. The interaction between fish density and fish size showed no significant effect (P>0.05) on the survival rate of tilapia fish seedlings. A fish density of 100 fish/liter and a fish size of 5-7 cm resulted in the highest survival of tilapia fry during semi-open transportation.

Abstract

Plankton is instrumental in the aquatic ecosystem, plankton can be an indicator of fertility and pollution. The quality of a water especially the flooded waters can be determined based on the fluctuations of the plankton population that will affect the trophic levels of the waters. The quality of a water can be measured by knowing the value of the Saprobic Index (SI). The Saprobic index is an index that closely relates to the pollution level. This research aims to determine the level of fertility and pollution levels in the waters of Telaga Tunjung Dam, based on the status of Trophic and Saprobic's structure of Phytoplankton, knowing the relationship (linkage) of trophic status and structure Saprobic phytoplankton with variable water quality in Telaga Tunjung Dam. The methods of study used are descriptive methods of case study. The research was conducted on five stations with four repetitions. Plankton sampling performed actively using plankton net with mesh size 60 μm diameter 25 cm. Based on the results of the status of the trophic waters in Telaga Tunjung Dam is at the head of high Water Fertility (Eutrofik). The pollution level is mild to moderate water with a saprobic index from 0,739 to -0,583. The trophic level relationship and the saprobic structure with the water quality variable show that good water quality affects the abundance of high phytoplankton and mild to moderate pollution levels.

Abstract

Snakehead fish (Channa striata) is a freshwater fishery commodity in Indonesia which has a high protein content. Many studies on the benefits of snakehead fish have resulted in an increase in the amount of demand for these fish. One of the production factors that support fish farming is feed. The snakehead fish seeds have an average length of 2 cm, with rudimentary digestive organs. Therefore, the most suitable feed as seed feed is natural food. Commonly used natural feed is water fleas (Daphnia sp.) and silk worms (Tubifex sp.). This study aims to determine the effect of a combination of feed on the growth of snakehead fish seeds and to determine the combination of feed that gives the highest growth in snakehead fish seeds. This research was conducted at the Fisheries Resources Development Laboratory, Warmadewa University for 60 days, from March to April 2020. The method used in this study was an experimental study using a completely randomized design (CRD) with six treatments and three replications. The analysis used in this study was Analysis of Variance (ANOVA), and continued with the Least Significant Difference (LSD) test. The results showed that there was an effect of combination feeding on the growth of snakehead fish as indicated by the increase in absolute weight and length. And the sixth treatment is a combination of feed that provides the highest growth in snakehead fish seeds.
