Fish culture plays an important role in supplying high-quality proteins and omega-3 (n-3) long-chain polyunsaturated fatty acids. Aquaculture has been the fastest growing sector agriculture. Fishmeal is component of commercial fish feeds, but ensuring a sustainable supply fishmeal question. A good source aquafeeds insects. For past 20 years, investigations have carried out on insect meals as alternative sources for fishmeal. Thus far, results replacing feeding aquaculture species promising. However, some challenging issues including costs scaling up production remains. In this review, we aim to summarize status applying eight formulated aquafeeds.

Replacement of fish meal with fermented plant proteins in the aquafeed industry: A systematic review and meta‐analysis

Reviews in Aquaculture, Journal Year: 2022, Volume and Issue: 15(1), P. 62 - 88

Published: June 5, 2022

Abstract In the aquaculture feed industry, fishmeal is widely used as a source of animal protein due to its high palatability, excellent amino acid profile and increased digestibility. However, incorporation in diets increases costs production declining wild fish stocks hence an urgent need search for sustainable cheaper alternative sources. The use fermented plant proteins substitutes has recently gained attention their improved nutritional quality, easy availability low costs. Therefore, systematic review meta‐analysis were conducted quantify effects on growth performance, utilisation, survival, antioxidant, metabolic digestive enzyme activity several species. Results indicated that replacement with enhanced antioxidant activities species regardless experimental duration protein. Likewise, (i.e., Alanine aminotransferase Aspartate aminotransferase) was reduced dietary treatment groups relative control groups.

Abstract The present work employed a systematic review and meta‐analysis to quantify the overall effects of various types insect meal on special growth rate (SGR), feed conversion ratio (FCR) protein efficiency (PER) aquatic animals. A total 107 studies published from 1990 2021, targeting 23 freshwater 17 marine fish species, employing species as replacement for fishmeal, was compiled. Overall, significantly higher Hedges’ g value SGR lower FCR found in animals fed dietary larval defatted mealworm Tenebrio molitor pupal full‐fat silkworm Bombyx mori compared with fishmeal diet. majority meals had negative linear correlation performance, except fly Chrysomya megacephala , which positive relationship, prepupal black soldier Hermetia illucens quadratic relationship. Some meals, including G . bimaculatus adult grasshoppers Oxya fuscovittata Zonocerus variegatus Cirina butyrospermi supported adequate at plausible inclusion levels.

Abstract Feeding cost is among the main drivers in price competitiveness of intensively‐fed‐aquaculture (IFA) products. As soaring energy prices increase costs technologies used to digestibility plant protein feeds, there an urgent call for comprehensive knowledge on mass use insects as fish feed. This review identifies key aspects insect incorporation into established IFA practices and puts them a commercial context. Larvae Black soldier fly (BSFL) identified most versatile terms (a) variety biowaste usable its rearing, (b) automatization scaling up, (c) nutritional value (d) circular environmental aspects. Furthermore, modifications diets can levels valuable compounds such omega‐3 fatty acids fish. Other ants or mealworms have potential meet requirements various species. While today production BSFL (mostly around 3.5 € kg −1 ) are mostly determined by labour costs, it predicted that intensified industrialization rearing could reduce below 2 . In addition, multiple positive economic impacts, well spillovers, been identified. It proposed further research should be directed towards refining valorization byproducts from farming which dissolve cost.

Chitin digestibility and intestinal exochitinase activity in Nile tilapia and rainbow trout fed different black soldier fly larvae meal size fractions

Aquaculture Research, Journal Year: 2022, Volume and Issue: 53(16), P. 5536 - 5546

Published: Aug. 14, 2022

Black soldier fly (Hermetia illucens) larvae meal (BSFLM) is a novel fish feed ingredient with high crude protein content (~40% dry matter, DM). However, BSFLM also contains chitin, which might impair nutrient digestibility. To investigate the effect of chitin on digestibility and chitinase activity in fish, different contents were tested as ingredients for Nile tilapia (Oreochromis niloticus) rainbow trout (Oncorhynchus mykiss). was sieved into three size fractions obtaining contents: 0–200 μm (fine), 200–400 (medium), >400 (coarse), 1.8, 2.7 15.4% DM basis, respectively. Four isoenergetic isonitrogenous diets formulated each species including an experimental reference diet replacing 25% matrix one fractions. Dietary inclusion coarse fraction resulted significantly lower apparent DM, protein, nitrogen-free extract when compared other treatment groups both species, supports hypothesis that act anti-nutrient. it found could digest but its decreased higher dietary level. Furthermore, β-N-acetylglucosaminidase (exochitinase) increased proximal distal intestine suggesting exochitinase production can be upregulated depending intake. Overall, results corroborate source well anti-nutrient trout.
