Abstract

Catfish is a freshwater consumption fish that is most widely cultivated in Indonesia, occupying the top position in total production, catfish has contributed more than 10% of the national aquaculture production with a growth rate of 17 to 18%. Catfish has a fairly high protein content and is very competent to improve human nutrition, because it is classified as a high quality food and its uniqueness is a must. Due to the high density of cultivation, a technology is needed that supports the maintenance of oxygen content, namely microbubble. This research was conducted for 50 days by observing the growth of catfish in 3 different conditions, namely without aerator, with conventional aerator and microbubble. The results showed that the absolute weight and absolute length without aeration were 5.2 g and 3.5 cm. then with a conventional aerator it produces 5.3 g and 3.5 cm. and on Microbubble it is 9.2 g and 7.2 cm. Judging from some of the parameter test results, it shows that raising catfish using microbubble increases the growth rate and productivity of catfish.

Abstract

Silkworms, as natural food, have an essential role because they can stimulate fish growth. However, silkworms in nature are not always available all year round, so it is necessary to cultivate silkworms. Silkworms need a medium containing organic matter and inorganic matter for their growth. Catfish farming wastewater contains a lot of organic matter. This study aims to evaluate the effect of catfish farming waste (Clarias sp.) on the growth of silkworms (Tubifex sp.) in different initial biomasses. This research method uses the experimental method Complete Randomized Design with four treatments and three repeats. The treatment used is P1 = 15 grams of silkworms; P2 = 20 grams of silkworms; P3 = 25 grams of silkworms; and P4 = 30 grams of silkworms. For analyzing data use ANOVA with a 95% confidence level and the Lower Significance Difference test on SPSS. The results showed that the provision of catfish farming waste had a real influence on the growth of silkworms. Silkworms' absolute weight and biomass were highest in treatment four, which were 195.33 g and 0.112 g. Therefore, catfish farming waste has the potential to be used as raw material for silkworm feed.

Abstract

Sangkuriang catfish (Clarias gariepinus) is a type of freshwater fish which is the prima donna in Indonesia because it grows quite fast compared to other types. Feed is an important component in fish farming activities to support growth. An increase in the price of fish feed without an increase in the selling price of fish is a problem that must be faced by every farmer. Therefore, it is necessary to make efforts to find raw materials that are cheap and easy. The black soldier fly carcass is possible as an alternative to fish meal. Currently, the black soldier fly carcass is not widely used as a raw material for fish feed, even though this type of insect contains a relatively high protein source. The purpose of this study was to examine the potential of adding black soldier fly carcass meal for the growth and survival of Sangkuriang catfish. The black soldier fly carcass has the potential to be used as a substitute for fish meal as much as 50%. The formulated test feed contains 37-38% protein. Test feed performance was compared to control using Duncan's test. After acclimatization, the Sangkuriang catfish size 5-7 cm were randomly stocked into 15 aquariums measuring 100 cm x 50 cm x 51 cm with a stocking density of 25 fish/m3 and were fed 6% of the total weight of all test fish for 35 days. maintenance. The results showed that the growth of Sangkuriang catfish was significantly different between the 50% KL formulation test feed and the control feed (P<0.05). Using black soldier fly carcass meal can increase the absolute weight growth of 3.26 g to 5.22 g and the survival of sangkuriang catfish 77.33 – 86.67%.

Abstract

Daphnia magna is a small crustacean or often called a water flea that lives in fresh waters. According to Putri et al., (2015), the nutritional content of Daphnia magna is 39.24% protein, 4.98% fat, 4.32% carbohydrates, ash content 14.63%. One of the Daphnia magna foods that can be given is tofu pulp which has a protein content of 27.55% to support its growth. The aim of this research was to obtain the most optimal growth of Daphnia magna after being given fermented tofu dregs at different doses. The method used was an experiment with a completely randomized design consisting of 4 treatments and 3 replications. The treatment carried out consisted of giving fermented tofu dregs in Daphnia magna maintenance media with different doses, namely P0 (0 gr/control), P1 (20 gr), P2 (30 gr), P3 (40 gr). Based on the results of research that has been carried out, it was found that P2 treatment with a dose of 30 grams gave the highest growth of Daphnia magna at 1,460 individuals. The high number of Daphnia magna populations given a dose of 30 grams can be utilized optimally for the growth and survival of Daphnia magna. The research results obtained concluded that giving fermented tofu dregs at a dose of 30 gr (P2) was able to have a significant effect (P < 0.05) on the increase in the Daphnia magna population.
