“…Fish meal was successfully replaced by fermented copra meal for up to 40% in black tiger shrimp ( Penaeus monodon ) practical diet, 116 up to 20% of soybean meal in commercial milkfish diet 102 and 100% of soybean meal (6% of total protein) in juvenile grouper diets 117 . Additionally, fermented copra was added up to 30% in diets of rohu fingerlings and 14% of rabbitfish ( Siganus javus ) diets 118 without compromising performance and survival. Fermented copra meal at an inclusion rate of 15% in the maintenance diets of tilapia seeds also had higher digestibility than raw copra meal 119 …”

The aquaculture sector is steadily growing due to the increasing demand for healthy and cheap animal protein sources. Consequently, the high demand for nutritionally balanced aquafeed increases, but requires sustainable and feasible feed ingredients. However, the high cost of fish and soybean meals opens the door to looking for suitable non‐traditional feed ingredients. The processing of fruits results in high amounts of waste and by‐products, which are risky for the environment but rich in nutritional value. Recycling fruit waste in aquafeed is successfully applied and results in high growth performance, productivity and well‐being of aquatic animals. Fruit by‐products are also potential functional feed additives devoted to their high content of polyphenols, flavonoids, vitamins, minerals, polysaccharides and peptides. As functional components, fruit by‐products enhance the antioxidative and immune responses of aquatic animals and increase their tolerance for biotic and abiotic stressors. In light of reducing antimicrobial chemicals in aquaculture to mitigate antimicrobial resistance, dietary feed additives extracted from fruit by‐products can be used as eco‐friendly substances. The investigations involved in evaluating the incorporation of fruit by‐products and their derivatives in aquafeeds are explored in this review. An overview of the possibility of using non‐traditional plant products in aquaculture as a feasible and sustainable concept is addressed in this review. Academic knowledge with enough information for more development and research to maximise the utilisation of fruit by‐products in the aquafeed industry is also enriched.

“…The appropriate regression model was selected based on the significant model and r-squared value (Bhujel, 2008;Yossa & Verdegem, 2015). The estimated optimal inclusion level of OM for maximum growth rate was determined by a significant polynomial regression followed by a broken-line regression procedure following the methods of Yossa & Verdegem (2015) and Laining et al (2017). Biochemical responses among the treatment groups were analyzed by one-way ANOVA with multiple comparisons evaluated using Tukey's test to compare the treatment effects.…”

The positive effect of organic mineral as a dietary mineral source in aquafeed has been recently reported on several species. Nevertheless, the influence of organic minerals on rabbitfish has not yet been determined. The purpose of the present study was to evaluate the effects of different doses of organic mineral on growth and survival, and mineral content in vertebrae of golden rabbitfish, Siganus guttatus. Three diets were formulated containing 0.5%, 1.0%, and 2.0% organic material (OM). A control diet (OM0) did not contain OM. Instead, it was supplemented with an inorganic mineral mixture at a level of 1%. Three hundred fish were randomly selected and distributed in 12 cages to accommodate the four treatments with triplicates. The stocking density was 20 fish per cage. The initial body weight of fish used was 39.2 ± 0.3 g. Fish were fed the test diets twice a day for 150 days. A significant (P<0.05) cubic effect of the treatments was detected on all dependent parameters analysis, excluding feed intake. The influence of dietary OM was not significant for feed intake, indicating that dietary OM did not negatively affect the appetite of rabbitfish. Mineral (Ca, Mg, Zn) content in the vertebrae was significantly improved when dietary OM was included in the diet up to 1% but decreased at the highest inclusion level of 2%. The optimum level of dietary OM to gain the maximum growth rate of rabbitfish was 0.49% as the reflection of the breakpoint of two regressions fitted on specific growth rate (SGR). It is concluded that dietary OM level significantly affected the growth and vertebral mineral content of golden rabbitfish. The study increases our knowledge of the benefit of utilizing dietary OM in the fish diet.

“…All dry ingredients were mixed thoroughly and oil containing lipid solubled-vitamins and carotenoid was added and then mixed again for 30 minutes. Further, water was added at level of 350-400 g/kg of the dry ingredients (Laining et al, 2017a). The mixture was then passed through a pelletizer (Hiraga, Co. Ltd, Kobe, Japan) and dried in oven.…”

“…Golden spotted rabbitfish, Siganus guttatus is considered to be a promising candidate for marine aquaculture development by virtue of its herbivorous/omnivorous feeding habits and consequent ability to feed low on the aquatic food chain (Duray, 1998;Tacon et al, 1990). In nature, rabbitfish feed on algae, seaweed, and other aquatic plants (Parazo, 1990;Bariche, 2006;Jaikumar, 2012) and in captivity can readily to accept artificial feeds, making them feasible to be grown on commercial scale (Tacon et al, 1990;Laining et al, 2017a).…”

A four months feeding trial was conducted to evaluate the effects of two maturation diets containing either fishmeal (FM) or squid liver meal (SLM) as the major protein source on growth, gonadosomatic index and gonadal bio-chemical profiles of golden spotted rabbitfish, Siganus guttatus. The two tested diets were formulated to be iso-nitrogenous (40%) and iso-lipidic (14%) and supplemented with several micronutrients specifically for gonadal development. The initial weight of golden spotted rabbitfish used were 352.6 ± 45.0 g and stocked into four of 2 m x 2 m x 2.5 m net cages with 25 fish per cage. The test diets were fed to the stocks twice a day. After four months feeding, the weight gains (WG) of broodstock fed the two diets were nearly similar in which FM had WG of 40.1 ± 2.2% and 42.8 ± 2.0% for SLM. The GSI of male fed SLM diet was similar to that of fed with FM. However, the GSI of female fed FM was 5.6 ± 0.1% significantly lower (P<0.05) than SLM which was 11.4 ± 0.5%. Furthermore, total amino acid (TAA) in spermatocyte was significantly (P<0.05) influenced by dietary SLM indicated by its higher TAA (62.4%) compared to TAA content of FM group (46.1%). Similarly, the TAA content in oocyte was significantly (P<0.05) improved when fed SLM. The dietary SLM did not affect the TAA content in the fillet of rabbitfish demonstrated by the similarity of the fillet TAA content in the two groups which was 55.6% for FM and 54.1% for SLM. Dietary SLM enhanced GSI of female broodstocks and profile of amino acid in the gonad of golden spotted rabbitfish, Siganus guttatus.
