Abstract

Feed is one of the important components of aquaculture. The higher the feed price, it is necessary to look for alternative materials for feed ingredients. One of the alternative feed ingredients that can be used is rice bran. In certain seasons, rice bran production decreases. One of the ingredients that can be used as a substitute for rice bran is nipa leaves. This study aims to determine the effect of using nipa leaves meal to replace rice bran in feed formulations and to examine the best percentage of nipa leaves meal on the growth and survival of striped catfish. This study used a completely randomized design (CRD) which consisted of 5 treatments (P) with three replications, namely P0 (0% nipa leaves meal: 20% rice bran), P1 (5% nipa leaves meal: 15% rice bran), P2 (10% nipa leaves meal: 10% rice bran), P3 (15% nipa leaves meal: 5% rice bran), and P4 (20% nipa leaves meal: 0% rice bran). The size of fish used in this study was 4±0.5 cm with a sticking density of 1 fish/L. The rearing of the study was 42 days. Research results show that using nipa leaves meal as a substitute for rice bran with different significantly affects the growth of absolute weight, absolute length, feed efficiency, and protein efficiency ratio. Research results show that the P4 treatment with a percentage of 20% nipa leaves meal: 0% rice bran is the best result with absolute weight growth (2.70 g), absolute length growth (3.35 cm), feed efficiency (85.88%), the protein efficiency ratio (2.66%), and survival (100%). Water quality obtained during rearing is temperature 25.2–31.2oC, pH 6.9–8.7, and dissolved oxygen (DO) 5–6.1 mg/L.

Abstract

Fish feed is known to account for 60-70% of total aquaculture costs, posing a significant challenge to farmers. To address the issue, this study explored the effectiveness of periodic starvation in improving feed efficiency and growth performance of climbing perch while reducing the cost of purchasing feed. The method used was a completely randomized design (CRD) analyzed using ANOVA. Four treatments were applied with three replicates each. The treatments consisted of P0 (no fasting), P1 (one day of fasting followed by one day of feeding), P2 (one day of fasting and two days of feeding), and P3 (one day of fasting and three days of feeding). The parameters observed included feed efficiency, growth in length and absolute weight, and fish survival rates. The results showed that periodic starvation significantly impacted the absolute body weight growth and feed efficiency (P<0.05). However, no effect was observed on the survival rates and absolute length growth. Among the treatments, P1 showed the best results, with feed efficiency of 21.87%, length growth of 0.23 cm, weight growth of 0.22 g, and survival rate of 100%. In conclusion, this study found that periodic starvation combined with feeding could significantly improve fish feed use efficiency and save fish farmers' costs.

Abstract

Silk worms is commonly used as natural feed for larval on fish hatchery. Cultivating silk worms requires a substrate as well as a feed source to support their growth. Fermented quail manure, tofu waste, and tapioca flour can be utilized as cultivation media for silk worms. This activity aims to apply the use of fermented quail manure, and tofu dreg, and tapioca flour on the growth of silk worms at Unit Pembenihan Rakyat D5 Suka Pindah Village, Ogan Ilir, South Sumatera. This activity is community service through extension and silk worm culture using media from fermented quail manure and tofu dregs. Silk worm cultivation was carried out using a closed-flow water system with two containers, one for fermented media and one for non-fermented media. Silk worms 150 g m-3 were stocked and reared for 30 days. The results obtained from community extension are an increase in understanding of the target audience from quite good to good and very good. The result of the silk worm culture demonstration plot show that absolute biomass growth in the fermented media at 588.80 g m-2 compared to non-fermented media at 440.00 g m-2 Therefore, fish farmers can apply silk worm culture with fermented media to be able to provide natural feed of fish, independently.

Abstract

Catfish (Clarias gariepinus) that are reared with probiotics as biofloc-forming agent is thought to increase the fish production. Applying swamp probiotics to the water media has never been studied to ensure the flocks' availability in the rearing media. This study aimed to determine the appropriate frequency of probiotics application collected from swamps for biofloc formation to improve the catfish production. This study used a completely randomized design with two treatments and three replications. The treatments were composed of different application frequency of swamp probiotics: (P1) once in 42 days of rearing and (P2) twice in 42 days of rearing. Data on flock volume, total bacterial colonies, absolute growth rate, feed efficiency, survival rate, and water quality were analyzed by T-test with a 95% confidence level. Meanwhile, the flock composition data were analyzed descriptively. The results showed that P2 obtained the best treatment with a floc volume of 68.33 10.41 mL/L, absolute length growth of 8.18 1.03 cm, absolute weight growth of 19.30 3.12 g, feed efficiency of 135.24 7.98%, survival rate of 89.33 6.21%, biomass production of 24639.50 1344.51 g, temperature of 28.85-29.59C, pH of 7.27-7.42, dissolved oxygen (DO) of 3.91-5.72 mg/L, ammonia of 0.45-1.15 mg/L, and total dissolved solids (TDS) of 717.33-885.50 mg/L. Therefore, swamp probiotics should be applied to catfish culture media twice for 42 days of rearing or once every 21 days.Keywords:BioflocCatfishProbiotics from swamp

Abstract

Graphical Abstract   Highlight Research 1. Production of Haematococcus microalgae using optimum Walne fertilizer media in snakehead fish farming waste. 2. Utilization of UV and/or ethanol to increase lipid production in Haematococcus. 3. Changes in the fatty acid composition of Haematococcus microalgae after UV and/or ethanol treatment. 4. Haematococcus protein levels decrease when treated with UV and/or ethanol.   Abstract Haematococcus pluvialis is a single-celled green microalga that is a possible source of bioactive compound. H. pluvialis cultivation mostly employs pro-analysis media, with organic components frequently limited. The use of wastewater from snakehead fish rearing to cultivate H. pluvialis to produce necessary fatty acids and amino acids has never been investigated. Environmental stress-induced physical treatment is likely to boost lipid production. There have been very few investigations on fatty acid composition in lipid synthesis from H. pluvialis cultivated in fish-rearing effluent. The purpose of this work was to assess the potential of snakehead fish wastewater (SFWW) as a culture medium for H. pluvialis, as well as to examine the fatty acid and amino acid properties of the microalga after exposure to UV and ethanol stress during the stationary phase.  The study consisted of two sequential experiments:  optimizing growth to determine the optimal Walne medium supplementation for H. pluvialis growth in SFWW, and inducing stress to assess the effects of ethanol and UV irradiation on H. pluvialis biochemical. The results showed that the SFWW medium supports the growth of H. pluvialis, with addition of 0.75 ml L-1 Walne medium achieving the highest densities (28.13±0.38 ×106 cells mL−1). Ethanol and UV are excellent at inducing stress in H. pluvialis. The maximum lipid percentage was seen in the Ethanol-UV treatment, but this stress also reduced H. pluvialis protein content.  SFWW can be used to cultivate H. pluvialis by supplementing Walne. Further research is needed on treatments that can increase long-chain unsaturated fatty acids.

Abstract

Coffee husk fermentation (CHF) might be utilized as an alternative plant protein source. This research evaluated dietary CHF supplementation's effects on growth for striped catfish. This study consisted of five grade levels of CHF as a treatment. The treatments were P0 (without the addition of CHF), P1 (addition of 6% CHF), P2 (addition of 12% CHF), P3 (addition of 18% CHF), and P4 (addition of 24% CHF). The results determined that dietary CHF inclusion had no significantly different effect on specific growth rate (SGR) and feed efficiency (P > 0.05). However, the P1 group (6% CHF) produced the best protein retention (PR), which was significantly different from the control (P0) and other CHF treatments (P < 0.05). No significant differences were observed in survival rates among the treatments. The inclusion of CHF up to 24% in the diet was found acceptable, as it did not negatively impact the striped catfish’s overall health or growth performance. Although growth rate, feed efficiency, and survival did not significantly differ (P > 0.05).
