Abstract

The global demand for coffee is increasing each year, and as a result, the number of debris that will be generated will also be as large as coffee husks. Therefore, efforts must be made to employ coffee husks. In the disciplines of biogas, fertilizers, bioethanol, biofuels, enzymes, and bioactive compounds, efforts have been made to utilize coffee husks. However, only two researchers have investigated the use of coffee husks as an alternative raw material and preservative for tilapia flesh in the fisheries industry. This article explains the prospective use of coffee husks in the fisheries sector, particularly in fish farming and processing.

Abstract

Tilapia (Oreochomis niloticus) is one of Indonesia's freshwater fish which has economic value. One way to obtain optimal fish hatchery results is by improving reproductive performance, which can be increased by improving the nutritional quality of the parent feed. The nutritional elements that must be present in the main fish feed include vitamin E and fatty acids. Vitamin E has a very important and decisive role in fish reproduction, because Vitamin E functions as an antioxidant which can prevent the oxidation of unsaturated fatty acids in cells and as an antioxidant. Fatty acids present in the cell membrane can accelerate the embryogenesis process to run normally and reproduction results can be increased. Ovagrow is high-quality Vitamin E which is useful for maintaining the egg and sperm maturation process in the parent fish. Ovagrow is also useful for multiplying and improving the quality of eggs and sperm in brood fish. The purpose of this study was to determine the effect of giving different doses of ovagrow to accelerate gonadal maturation of tilapia and to determine the effect of adding ovagrow to gonadal maturity and egg fecundity in tilapia broodstock. The research method used a completely randomized design (CRD) which consisted of 4 treatments with 3 repetitions each. Treatment A ovagrow dose 0.3 gr/1 kg feed, Treatment B ovagrow dose 0.5 gr/1 kg feed, Treatment C ovagrow dose 0.7 gr/1 kg feed and Treatment D ovagrow dose (control) 1 gr/1 kg of feed. The results showed that the TKG of tilapia with the highest percentage was in treatment A and the best fecundity of tilapia was in treatments A and D with a total average value of 541.26. Based on the results of the research conducted, it can be concluded that administration of ovagrow at different doses did not have a significant effect on the gonad maturity level of tilapia broodstock and the average fecundity of tilapia (Oreochoromis niloticus).

Abstract

Gouramy (Osphronemus gouramy) is one of the freshwater fishery commodities that are in great demand by the public, both by consumers and cultivators. Consumers like gouramy because it tastes delicious and tasty, while cultivators like gourami because it has a higher selling price compared to other freshwater fishery commodities. Feed is an important component in fish farming activities. Feed is a source of material and energy to support the growth and survival of fish, on the other hand feed is also the largest component of 50-70% of production costs. The purpose of this study was to determine the effect of feeding a combination of pellets and vegetable feed on the growth and survival of gouramy and to see the best type of vegetable feed. The results of the research were the results of the test parameters measured during the study, namely absolute weight growth, specific weight growth, absolute length growth, specific length growth, feed conversion ratio (FCR), feed efficiency level (EPP), and survival rate (SR). As well as water quality data including the degree of acidity (pH), temperature, dissolved oxygen (DO), ammonia and alkalinity. The results of parameter measurements showed that the P4 treatment showed the best results for each parameter that had been observed. The effect of giving a combination of pellet feed and vegetable feed on gourami (Osphronemus gouremy) seed cultivation gave insignificant results on absolute weight growth, specific weight growth, absolute length growth, specific length growth, feed conversion ratio, feed efficiency level, and survival rate live gourami. Treatment 3 (a mixture of pellets and papaya leaves) gave the best results compared to other treatments.

Abstract

Catfish is a freshwater commodity often found in traditional and modern markets. Cultivation is also carried out in almost all regions, but the obstacle is feed availability. Therefore, we are looking for feed ingredients that are widely available and capable of increasing catfish growth quickly. Octopus is a fishery commodity abundant in certain seasons and requires processing so that it is not wasted. Octopus can be made into meal and used as raw material for catfish feed. The research aimed to analyze the effect of adding octopus meal to commercial feed for the growth of catfish (Clarias sp.). This research used an experimental method with 4 treatments (P1: 100% pellets, 0% octopus (without addition), P2: 98% pellets, 2% octopus meal, P3: 96% pellets, 4% octopus meal, P4: 94% pellets, 6% octopus meal) and 3 repetitions. The results showed that the addition of octopus meal increased the growth of catfish with the best treatment, namely the P4 treatment. Adding octopus meal to commercial feed gave significant results on absolute weight growth, specific weight growth, absolute length growth, specific length growth, feed conversion ratio, and feed efficiency level but did not affect the survival rate of catfish.

Abstract

Feed additives are added in small quantities to improve feed quality and improve feed efficiency. Seaweed can be used as a feed additive because it contains nutrients such as protein, carbohydrates, fats, and minerals. One type of seaweed that can be used as a feed additive is Kappaphycus alvarezii. The step to maximize the nutritional content of seaweed flour is through fermentation. The purpose of this study is to determine the effect of the long fermentation time of bioflocculants on Kappaphycus alvarezii as an additive in feed for the growth and efficiency of goldfish feed utilization. This study used a Complete Random Design method with three treatments and four replicates, namely P0 (Fermentation 144 hours (6 days)), P1 (Fermentation 192 hours (8 days)) and P2 (Fermentation 240 hours (10 days)). The results showed that P2 treatment had a real effect on absolute weight, absolute length, specific growth rate, feed utilization efficiency (EPP), feed conversion ratio (FCR), but had no effect on the survival rate of goldfish. The best treatment in this study refers to the absolute length value, feed conversion ratio, and feed utilization efficiency, namely P2 treatment. Meanwhile, referring to the absolute weight value and specific growth rate, the P2 and P1 treatments were better than the P0 treatments.

Abstract

Abundant organic waste has the potential to pollute the environment, so proper management is needed so that organic waste can become an economically valuable material. Bioconversion by maggot Hermetia illucens (Black Soldier Fly) is one of the effective methods to process organic waste into animal protein sources that can be used as fish and livestock feed. BSF maggot is able to reduce organic waste up to 78.9% per day and has a protein content of 30-45% and fat 24-30%. The maggot life cycle involves several phases from egg to adult, with temperature playing an important role in this process. Maggot also shows great potential in improving fish growth and health, and can be used as an efficient and highly nutritious alternative feed ingredient.

Abstract

This study aims to evaluate the effect of olive oil supplementation in commercial feed on the growth and survival rate of milkfish (Chanos chanos) fry. The research used a Completely Randomized Design with five treatments and three replications: control without oil addition (A), fish oil 1 ml/30 g feed (B), olive oil 0.5 ml/30 g feed (C), olive oil 1 ml/30 g feed (D), and olive oil 1.5 ml/30 g feed (E). The results showed that olive oil supplementation significantly affected growth and survival (p<0.05). Treatment D (olive oil 1 ml/30 g feed) demonstrated the best performance with absolute weight growth of 0.40 g, relative weight growth of 366.7%, specific daily weight growth rate of 3.48%/day, and relative length growth percentage of 172.2%. This treatment resulted in the highest survival rate of 86.7%. These values were significantly higher compared to other treatments, including fish oil supplementation. These findings indicate that olive oil supplementation at a dose of 1 ml/30 g feed can effectively optimize the growth and survival of milkfish fry, and has the potential to become a sustainable alternative to fish oil in aquaculture feed formulations.
