“…In this study, proximate analysis showed the higher moisture content in (84.25 ± 1.0) in vitamin C‐enriched group, while higher protein content (9.80 ± 0.40) and ash content (0.78 ± 0.01) in HUFA‐enriched group. This nutritional quality is comparable with the work of (Pratiwy et al, 2021) reported the proximate analysis of fish oil‐enriched Daphnia sp. as a live food and found crude protein percentage 10.55%, crude fibre 0.59%, moisture content 87.67% and crude ash 0.18%.…”

Water quality parameters recorded in this study were in the convenient spectrum for the rearing of C. magur larvae during the entire experiment period. The temperature fluctuates from 27 to 28°C, water pH from 7 to 7.9, dissolved oxygen between 5.0 and 5.7 ppm, total alkalinity from 150 to 170 ppm, hardness from 80 to 110 ppm and free carbon dioxide from 0.3 to 0.7 mg L −1 .…”

Asian catfish, Clarias magur (Hamilton, 1822), known as magur, is a popular food fish in Asian countries because of its high nutritional and medicinal value. Aquaculture of magur is constrained by non‐availability of seed due to very high mortality during the early larval stages. The strategies to enhance the larval survival during the early stages could be a major step in enhancing the seed production of this species. So, the aim of the present study was to assess the effect of highly unsaturated fatty acids (HUFA)‐ and vitamin C‐enriched infusoria on the growth and survival of C. magur larvae. Eight‐day‐old larvae with an average weight of 3 mg and length of 5 mm were stocked in plastic crates (30 x 20 x 18 cm) each containing 40 litres of water. A total of 16 crates were used in experiment and in each crate 100 larvae were stocked. The larvae were fed three times daily with HUFA, vitamin C, both HUFA and vitamin C and un‐enriched infusoria @ 9–10 numbers per ml of rearing water for 30 days in four different treatment groups. The proximate analysis of different enriched and un‐enriched infusoria showed the highest (84.25%) moisture content in HUFA‐enriched Infusoria, and the highest percentage of crude protein (9.80%), crude lipid (3.50%) and ash content (0.78%) in vitamin C‐enriched Infusoria. The survivability analysis showed the highest survival in the treatment group fed with HUFA‐enriched infusoria (49.25%) and the lowest in the control group (18.25%). This indicates that the enrichment of infusoria with HUFA could increase the survival rate significantly. The highest body weight gain (55.75 mg) was observed in HUFA‐enriched group but not significantly different from the control group. The study indicates that the enrichment of infusoria with HUFA have a significant influence on larval survival.

“…In general, the protein requirements are higher at the early life stage of fish, and it will decrease as fish grow larger. The dietary protein requirement also depends on the various environmental factors such as water temperature, water quality, dietary protein energy and feeding frequency of the fish, (Craig et al, 2017). This has also been explored in a prior study by Singh et al (2016) revealed that body weight gain and hepatosomatic index (HSI) in Asian catfish, Clarias batrachus fry was influenced by the temperatures.…”

“…About 200 amino acids occur in nature, but only 20 amino acids are prevalent in fish. From these 20 amino acids, 10 are essential (indispensable) amino acids that cannot be produced by fish and must be supplied in fish feed (Craig et al, 2017), such as arginine, histidine, isoleucine, leucine, methionine, phenylalanine, threonine, tryptophan, and valine. The other 10 are non-essential (dispensable) amino acids, for example, alanine, asparagine, aspartic acid, cystine, glutamic acid, glutamine, glycine, proline, serine, tyrosine, (Barnie, 2013).…”

“…However, protein will not work alone; it will be utilized for fish growth if an adequate amount of other nutrients such as lipids and carbohydrates are present in fish feeds or diets. In this case, protein is quite expensive; the absence of lipid and carbohydrates will cause more protein to be used for energy and life support rather than growth, (Craig et al, 2017). Furthermore, based on Table 1, zebrafish must have ten indispensable or 'essential' acids (EAAs) to ensure protein synthesis.…”

Zebrafish Nutrition: Promoting Fish Health and Welfare of the Animal Model in Halal Science Research

Zebrafish (Danio rerio) is a popular animal model in a variety of fields, including molecular biology, neurology, genetic research, aquaculture, and even halal science research. As the use of zebrafish in research grows, so does the need to focus on their welfare to ensure that they live in normal-good health, fit for research. Nutrition is an important but often overlooked welfare factor in zebrafish, as it affects their development, health, reproduction, and response to stimuli. In many modern laboratory settings, zebrafish feeding is dependent on the researcher, with numerous types of feed and feeding regimens used without a rigorous assessment of the fish growth. This is largely owing to a lack of information about zebrafish nutritional requirements, which is regarded as the most fundamental fault in any nutritional and growth study. A standard fish diet with an adequate amount of nutrition including the appropriate ratio of protein, carbohydrate, lipids, vitamins, and minerals are proposed to prevent the unplanned nutritional effect to the outcomes of such experiments. Protein is important for the growth of the fish while carbohydrates and lipid are the non-protein source of dietary energy for the fish diet. Feeds with the proper amount of dietary ingredients can help the fish live at optimum health. Islam teaches zero-tolerance to all forms of animal abuse throughout the halal production supply chain and although not many, there is a few number of demands on animal welfare as a purchase criterion. Therefore, as far as halal science is concerned, care must be taken to ensure the protection and welfare of laboratory animals utilized in research.
