“…The availability of different food sources for live feed enrichment is crucial in providing better quality in a large quantity of live feed sources for aquatic organisms (Kandathil Radhakrishnan et al, 2020; Yuslan et al, 2021a). There are many studies on the enrichment of live feeds focused on using only microalgae as the main and common food sources (Latib et al, 2020).…”

The copepod Oithona rigida can be used as a natural feed in rearing larvae of the mud crab Syclla olivacea. However, copepod is not readily obtainable due to their characteristics as seasonal zooplankton, causing limitation in using copepods. The objective of this study was to evaluate the nutrient transfer of enriched O. rigida in improving the growth development and survival of early‐stage mud crab (Scylla olivacea). The effects of different feeding regimes on the survival and development of S. olivacea larvae were studied in two phases of the crab larval development: Phase 1 (zoea 1 to zoea 2 stage) and Phase 2 (zoea 5 to megalopa stage). The feeding regimes were T1: O. rigida enriched with rice bran, T2: O. rigida enriched with Nannochloropsis oceanica, T3: O. rigida enriched with a mixture of rice bran and N. oceanica, and T4: Artemia. The results showed that rice bran (66.83 ± 2.25% protein and 21.98 ± 1.41% lipid) and N. oceanica (72.08 ± 2.02% protein and 18.09 ± 1.18% lipid) additives produced the best outcomes in terms of protein content and lipid content of O. rigida. A mixture of rice bran and N. oceanica (41.62%) as enrichment also improved the polyunsaturated fatty acids (PUFAs) content of O. rigida as compared with a mono diet applied such as rice bran (28.16%) and N. oceanica (31.35%). The average survival rate of S. olivacea from zoea 1 until megalopa shows that T3 (20.20 ± 1.97%) was higher than T1 (13.87 ± 0.90%), T2 (12.47 ± 1.14%) or T4 (3.13 ± 1.29%). In conclusion, improving the survival rate of crab larvae in commercial hatcheries by using precise early‐stage foods is fundamental to enhancing the seed production technology of mud crabs.

Aquaculture is the farming of aquatic organisms like fish, crustaceans, mollusks, and aquatic plants, which has become a crucial source of protein and income. However, bacterial infections pose a significant challenge to the aquaculture industry and traditional treatments, such as antibiotics and chemicals, have limitations and environmental concerns. Disease prevention and control measures, such as the use of probiotics, vaccines, and biosecurity measures, are essential for the sustainable development of the aquaculture industry. Further research is also needed to develop more effective and sustainable strategies for the prevention and control of bacterial fish pathogens in aquaculture, where alternative treatments such as herbal extracts, essential oils, and probiotics require further investigation for efficacy and safety. Microalgae, particularly Chlorella, have potential applications in various industries such as biofuels, pharmaceuticals, and wastewater treatment. However, their large-scale production and commercialization face challenges. Safety of Chlorella to fish is a crucial issue that requires careful evaluation, with hematology being an essential tool to assess its effects on fish health and physiology. Studies show that Chlorella is safe for fish and does not have adverse effects on growth, survival, or immune system function. Chlorella is a safe and sustainable option for aquaculture, free from harmful chemicals and antibiotics. The Green Water System utilizes Chlorella as a natural filter and nutrient recycler, improving water quality and providing a well-balanced diet for aquatic animals. This eco-friendly approach also enhances fish immune systems, growth rates, and survival rates. The scientometric review shows significant research activity, with Chang JS being a prominent author and People’s R China and the Chinese Academy of Sciences leading in contributions. The use of Chlorella shows promise as an alternative treatment for bacterial fish pathogens in aquaculture due to its antibacterial properties, safety, and sustainability. However, challenges such as cost-effectiveness and standardization need to be addressed for successful implementation in the aquaculture industry.

Utilising novel ingredients in aquafeeds is necessary for the continued expansion and intensification of aquaculture production. Microalgae are utilised widely in aquaculture for a variety of purposes; as live feed for fish and shellfish larvae and juveniles, for the production of algae‐based meals and oils to replace marine derived raw materials in aquafeeds, and for the production of astaxanthin, the carotenoid that gives salmon flesh its characteristic reddish colour. Notably, long‐chain polyunsaturated fatty acids, amino acids, proteins, fibres, antioxidant pigments, vitamins and minerals are among the compounds in microalgae with great biological value. A growing collection of experimental data has demonstrated that these substances are crucial for increasing larval survival and enhancing the growth and well‐being of fish and shellfish. In this review, the processing of microalgae utilised as aquafeed ingredient, the health promoting compounds in microalgae and their role in growth, immunity and disease resistance of fish and shellfish are described and discussed. Simultaneously, major hurdles in the commercial use of microalgae in aquafeed, and future research and development perspectives are all critically discussed.
