Abstract

Aquaculture is one of the world's most rapidly expanding producers of protein-rich diets. This is in accordance with the rising demand for feed to sustain these activities. However, the use of natural materials for fish feed, particularly fish oil, creates a paradox because it is derived from fish, therefore it is against the principles of sustainable agriculture. This article examines vegetable oils with a superior nutritional profile, palatability, digestibility, anti-nutritional factors, availability, and cost in comparison to fish oil. The ten-year-old articles selected and compiled originate from national (SHINTA) and international (Elsevier and Proquest) websites. Finding alternatives to fish oil as a source of lipids in fish diets is the result of several decades of research. Vegetable and animal sources are two main types of fish oil substitutes. Up to one hundred percent of fish oil can be substituted with vegetable oils like palm oil, canola oil, soybean oil, and olive oil. Similarly, animal sources can provide up to 75% of the lipids necessary for fish diets. Moreover, rubber seed oil has the potential to supplant fish oil in Indonesia due to its high omega-3 fatty acid content, which is comparable to that of fish oil. The conclusion of this review is that there are multiple sources of lipids that can be used to replace fish oil, and that more consideration must be given to the type of lipid source used in accordance with the type of fish being cultivated and the location of the fish cultivation.

Abstract

The use of pineapple fruit extract as an immunostimulant in aquaculture has become the focus of significant research in efforts to improve the immune systems of aquatic organisms, especially farmed fish. Pineapple fruit extract, which contains bromelain, has attracted attention as a potential natural solution to improve the immune response of fish against pathogens and disease. The main aim of this review is to evaluate the extent to which the use of pineapple as an immunostimulant is effective in improving the immune system of fish or other aquatic organisms in an aquaculture context. This article uses literature study methods from several national, accredited national journals and reputable international journals. Literature study is the process of searching, collecting and analyzing various sources of information relevant to a particular topic. Pineapple extract contains bromelain, which has immunomodulatory and anti-inflammatory properties. It can improve the fish's immune response and reduce inflammation, helping to improve fish health. The use of pineapple fruit extract can reduce dependence on antibiotics in the treatment of sick fish, which is in line with global efforts to overcome antibiotic resistance and environmental impacts. With the right efforts, the use of pineapple fruit extract as an immunostimulant in aquaculture has the potential to increase the productivity and sustainability of the aquaculture industry, as well as reduce dependence on antibiotics and synthetic chemicals. Therefore, further research and development of best practices in the use of pineapple fruit extract in aquaculture are necessary steps to realize its potential as a more environmentally friendly and sustainable alternative.

Abstract

Nile tilapia (Oreochromis niloticus) is a high-value aquaculture commodity with steadily increasing market demand. However, the growth performance of Nile tilapia fingerlings is often hindered by suboptimal feed quality and high mortality rates. One innovative approach to address these challenges is the incorporation of herbal probiotics as feed additives. This study aimed to evaluate the effect of herbal probiotic supplementation (Probal) on the growth, feed efficiency, and survival of Nile tilapia fingerlings. The research was conducted over 28 days at the Laboratory of Fish Production and Reproduction, Faculty of Agriculture, University of Mataram, using a Completely Randomized Design (CRD) with four treatments and three replications: P1 (control), P2 (Probal 2.5%), P3 (Probal 3%), and P4 (Probal 3.5%). The observed parameters included absolute length and weight gain, specific growth rate (SGR), feed conversion ratio (FCR), feed utilization efficiency (EPP), feed consumption, survival rate (SR), and water quality. Results showed that P4 treatment significantly outperformed other treatments in terms of length gain (2.39 cm), weight gain (13.8 g), SGR (3.26%/day), and SR (93.33%). Although no significant differences were observed in FCR and FUE, Probal supplementation was proven to enhance growth performance and survival. Therefore, herbal probiotic supplementation represents a promising and environmentally friendly strategy for sustainably improving Nile tilapia aquaculture productivity.

Abstract

Feed stability is crucial in aquaculture to minimize nutrient loss and ensure optimal growth of cultured species. This study evaluated the effects of different binders (carboxymethyl cellulose/CMC, wheat gluten, tapioca flour, and Gracilaria sp. flour) at 3% and 5% concentrations, processed via hot and cold mixing methods, on feed stability and survival of mud crab (Scylla spp.). Conducted over 45 days, the research involved feed formulation, stability testing in seawater (30 ppt salinity), and a 30-day feeding trial in a recirculating aquaculture system. Results showed that binder type and processing method significantly influenced feed integrity, with CMC 5% + hot mixing exhibiting the highest stability (96.99% retention after 240 minutes), while tapioca 5% + hot mixing degraded fastest. All formulations met the ≥70% stability threshold after 120 minutes, confirming suitability for aquaculture. The feeding trial revealed 100% survival across all treatments, indicating that binder selection can prioritize physical stability without compromising crab health. Hot processing consistently enhanced binder performance, particularly for polysaccharide-based CMC and Gracilaria sp. flour. These findings suggest CMC 5% (hot) as the optimal binder for durable mud crab feed, whereas tapioca requires careful concentration control. The study provides practical insights for feed development, though further replicated trials under varied farming conditions are recommended to validate commercial applicability. This research contributes to sustainable aquaculture by improving feed efficiency and reducing waste in mud crab production.

Abstract

The study examines the effects of supplementing coffee grounds to commercial feed on the growth, feed utilization and survival rates of Nile tilapia (Oreochromis niloticus). Given that feed quality and environmental conditions significantly impact fish productivity, the inclusion of coffee grounds, rich in antioxidants and potential immunostimulants, was hypothesized to enhance fish growth and health. The experiment, conducted over 45 days, involved five treatments with varying coffee ground concentrations (0%, 2%, 4%, 6%, and 8%) within a Completely Randomized Design (CRD). Each treatment was replicated three times, resulting in a total of 15 experimental units. Results indicated significant improvements in growth parameters, including absolute weight and length, relative growth, and specific growth rates, particularly at the 6% concentration. However, feed conversion ratio (FCR) and feed utilization efficiency (EPP) did not show significant differences. The study concludes that a 6% coffee ground concentration is optimal for promoting tilapia growth without adversely affecting feed efficiency.

Abstract

Nile tilapia (Oreochromis niloticus) is a widely cultivated freshwater fish due to its adaptability to various environments and ease of breeding. Feed availability is a crucial factor in the success of tilapia cultivation. Quality feed plays a vital role in fish development and using effective feed management strategies can help reduce costs and improve growth outcomes. Previous studies have suggested that coffee grounds can enhance fish immunity and growth due to their antioxidant properties. This research aimed to investigate the impact of adding coffee grounds to commercial feed on the growth and survival of Nile tilapia. The study was conducted over 45 days using a completely randomized design with five treatments and three replications. Treatments included a control group (P1) and feed supplemented with 0.5g (P2), 1g (P3), 3g (P4), and 5g (P5) of coffee grounds per 100g of feed. The results indicated that the addition of coffee grounds significantly affected weight growth, with the highest growth observed in P5. However, no significant differences were found in length growth or specific growth rate (SGR) among treatments. Feed consumption was highest in P2, but feed conversion ratio (FCR) and feed utilization efficiency were most favorable in P5. Water quality parameters remained within optimal ranges throughout the study.
