Abstract

Nile tilapia is a high-value aquaculture commodity. Its production increased from 24.98% in 2018 to 26.76% in 2019, showing a 7.11% rise. In tilapia farming, feed is a major factor, but its high cost has encouraged the search for alternative feeds. Maggot offers a promising solution due to its low cost and high protein content (40–50%) along with essential amino acids. This research used an experimental method with a completely randomized design (CRD), consisting of 4 treatments and 3 replications: P1 (household waste), P2 (fruit waste), P3 (tofu dregs), and P4 (chicken manure). Egg hatching was carried out in plastic containers with a moist mixture of pellet and water. After one week, larvae were transferred to wooden rearing containers filled with 2 kg of each type of waste. The maggot rearing process lasted for two weeks. Maggots were harvested at three weeks old, then dried by roasting and used as fish feed. Tilapia were reared for 45 days in 12 aerated containers and fed maggots three times a day. Water quality was monitored weekly. The results showed that weight gain, specific growth rate (SGR), absolute length, specific length growth rate (SLGR), and blood glucose levels were significantly affected by the treatments. However, feed conversion ratio (FCR) and survival rate (SR) were not significantly different. The best results were obtained from P1 (household waste), with absolute weight gain of 11.42 g, SGR of 1.67%/day, absolute length of 4.92 cm, SLGR of 1.02%/day, FCR of 1.9, survival rate of 84.44%, and blood glucose level of 73.3 mg/dL.

Abstract

The cultivation of African catfish (Clarias gariepinus) using a biofloc system is an aquaculture technology that integrates waste management and the production of natural feed in situ, thereby enhancing productivity efficiently. This research aimed to evaluate the effect of EM4 probiotic application in a biofloc system on the growth and survival rate of catfish under different stocking densities. The experiment was conducted using a Completely Randomized Design (CRD) with four stocking density treatments: P1 (30 fish/30 L), P2 (40 fish/30 L), P3 (50 fish/30 L), and P4 (60 fish/30 L), each with three replications. Observed parameters included absolute weight and length growth, floc content, hematocrit, hemoglobin, erythrocytes, leukocytes, differential leukocytes and water quality parameters. The treatment P4 showed the most notable effects, with a final absolute weight gain of 11.66 grams and an absolute length increase of 8.11 cm. Furthermore, the probiotic addition had a significant impact on erythrocyte levels and differential leukocyte counts. In contrast, the use of probiotics in the biofloc system did not result in significant differences in hematocrit levels, total leukocyte counts, or biofloc volume.

Abstract

Cupang fish (Betta sp.) are included in the variety of freshwater ornamental fish with attractive and beautiful colors and bodies. However, male betta fish are more desirable. The purpose of this study was to determine the effect of immersing betta fish (Betta sp) broodstock using three different types of honey on the percentage of male fish through broodstock immersion. This study used a completely randomized design (CRD) with 4 treatments and 3 replications, namely P0 (control), P1 (forest honey), P2 (livestock honey), and P3 (mangrove honey), so there were 12 experimental units. Analysis of the percentage of male sex was carried out using analysis of variance (ANOVA) and Duncan's test. The calculation results show that the percentage of male fish in forest honey, livestock honey, and mangrove honey are 76%, 74%, and 92%, respectively. The results of the calculation of the survival rate ranged from 50 – 53%, the fecundity value ranged from 160 – 245 eggs, the hatching rate ranged from 53 – 58%, the absolute weight growth showed a relatively similar value, namely 0.61 – 0.70g, and the weight growth specifically shows a value of 2.84 - 2.90%. The water quality parameter values of temperature, pH and DO obtained during the study were still in optimal conditions for betta fish maintenance. Thus it can be concluded that the treatment using mangrove honey is the treatment with the highest effectiveness value for directing the sex of betta fish (Betta sp) to male.
