Abstract

Fisheries cultivation in Indonesia includes ornamental fish cultivation and consumption fish cultivation. One of the problems in consumption fish cultivation is usually due to inappropriate feed factors, which makes the cultivation process tend to be long and inefficient. This research aims to determine the right type of feed to support the absolute weight growth of 1 month old freshwater lobster (Cherax quadricarinatus) seeds. The method used was an experimental method using a completely randomized design (CRD) with 5 treatments and 5 replications. The test animals used were 1 month old lobster seeds with an initial average weight of 1.60, the seeds were obtained from the spawning of the Krian lobster cultivation breeders. Lobsters were reared and given food according to treatment in the form of P1 (pellets), P2 (maggot), P3 (silk worms), P4 (potatoes, P5 (Daphnia magna) for 30 days. The results of the research showed that P3 silk worm food gave the highest absolute weight growth, namely 1.29gr, then maggot P2 which is 0.79gr, potato P4 0.64gr, then pellet P1 0.55g and finally daphnia magna with a figure of 0.17gr Absolute weight growth is the main parameter observed as well as supporting parameters including water quality including temperature , pH, and dissolved oxygen.

Abstract

Siamese catfish (Pangasius hypophthalmus) is one of the leading freshwater commodities and has high economic value in Indonesia. Increasing cultivation intensity to meetdomestic and export market demand has direct implications for the high demand for quality seeds. Closed wet transportation is an important part of aquaculture activities. This method has significant advantages in terms of logistics efficiency. This study aims to assess the effect of density on closed wet transportation systems on the survival of Siamese catfish (Pangasius hypophthalmus) seeds with a size of 3-5 cm. This study is expected to provide recommendations for the transportation of the density of Siamese catfish (Pangasius hypophthalmus)  in size 3-5 cm. This study uses the analysis method of normality tests in spss, variety homogeneity tests, variety fingerprints and the smallest real difference (BNT). Treatment A = Fish density 100 fish/liter (0) (Control Treatment, Treatment B = 150 fish/liter, Treatment C = 200 fish/liter, Treatment D = 250 fish/liter. From the study, the most optimal density of Siamese catfish (Pangasius hypophthalmus) is the highest which is 200 fish/liter with an average SR of 98.08%. With water quality including: water temperature: 26.1 °C – 26.8 °C, water pH: 6.1 – 6.9 and Dissolved Oxygen (DO): 2.0 – 6.3 ppm.
