Can Insect Meal Replace Fishmeal? A Meta-Analysis of the Effects of Black Soldier Fly on Fish Growth Performances and Nutritional Values

Animals, Journal Year: 2022, Volume and Issue: 12(13), P. 1700 - 1700

Published: June 30, 2022

The search for quality alternatives to fishmeal and fish oil in the feed industry has occupied many researchers worldwide. use of black soldier fly meal (BSFM) as a substitute increased. This study evaluated effect this substitution on growth nutritional through meta-analysis literature. A list studies was selected after an exhaustive literature followed by extraction parameters. Two random-effects models were used estimate differences between experimental parameters controls. results showed significant heterogeneity all sources mainly species protein rate. High substitutions can be considered without necessarily worrying about adverse effect. Financial profitability production chain from BSFM should carried out validate or invalidate economic viability substitution.

Defatted black soldier fly (Hermetia illucens) in pikeperch (Sander lucioperca) diets: Effects on growth performance, nutrient digestibility, fillet quality, economic and environmental sustainability

Animal nutrition, Journal Year: 2022, Volume and Issue: 12, P. 7 - 19

Published: Sept. 12, 2022

The use of insect meal in aquafeed formulations has recently gained attention. Detailed knowledge about the inclusion levels for pikeperch (Sander lucioperca), a promising candidate intensive aquaculture Europe remains, however, fragmented. In present study, 4 isoproteic (45% dry matter) and isoenergetic (21 MJ/kg) diets were formulated, including control diet (H0) containing 30% fishmeal (FM) on an as-fed basis other 3 which FM protein was replaced by defatted black soldier fly (Hemetia illucens) (HIM) at 25%, 50%, 100% (diet abbreviation H9, H18 H36, corresponding to level 9%, 18% 36%, respectively). feeding trial performed triplicate groups 50 juvenile (mean weight, 68.7 g) fed with experimental 84 d during growth performance, nutrient digestibility, fillet quality economic environmental sustainability rearing evaluated.

Fish Meal Replacement and Early Mild Stress Improve Stress Responsiveness and Survival of Fish after Acute Stress

Animals, Journal Year: 2023, Volume and Issue: 13(8), P. 1314 - 1314

Published: April 11, 2023

Stress responsiveness and fish meal (FM) replacement are two of the most important concerns toward achieving sustainable aquaculture. The purpose this study was to see how early mild stress (netting) FM with meat bone (MBM) affected oscar (Astronotus ocellatus; 5.2 ± 0.9 g) growth, hematology, blood biochemistry, immune responses, antioxidant system, liver enzymes, responses. Oscars were subjected a 3 × experimental design (three levels: 250, 180 110 g/kg in diets; three periods: 0-, 2- 3-times stress). After ten weeks experiment, levels diets did not affect growth data, but survival rate after acute confinement (AC) lower 11FM treatments (47.7% compared 67.7%) than others. Fish exposed 3Stress schedule had (31.03 6.50 (55.5%) AC 2Stress group (38.92 6.82 g 70.0%). Lower groups coincided lowest performance, total protein, lysozyme, complement C4, C3, immunoglobulin, superoxide dismutase, catalase, glutathione peroxidase, highest glucose, cortisol, low-density lipoprotein aspartate aminotransferase serum levels. Altogether, revealed that it is possible replace MBM up 28% (180 FM) without negative effects on health juvenile as dietary impaired health. While welfare should be considered, we can conclude (2Stress) during farming period, adding excessive alternative protein sources, improve oscar.

Effect of feed ingredients on nutrient digestibility, waste production and physical characteristics of rainbow trout (Oncorhynchus mykiss) faeces.

Aquaculture, Journal Year: 2023, Volume and Issue: 574, P. 739621 - 739621

Published: April 27, 2023

This study assessed the effect of different dietary ingredients on quantity and characteristics faecal waste produced by rainbow trout (Oncorhynchus mykiss). Seven were tested: fish meal (FM), mussel (MM), poultry wet rendered (PM-W) or dry (PM-D), insect (IM), single cell protein (SCP) brewers grain (BGP). Eight experimental diets formulated: a control diet (CON) being predominantly plant-based seven test diets, which contained 70% CON 30% one ingredients. Rainbow juveniles (65 g, 30 fish/tank) fed at satiation for six weeks in triplicate groups. Dry matter (DM) nutrient digestibility measured. To estimate characteristics, particle size distribution (PSD) removal efficiency was determined. Nutrient differed significantly. Growth did not differ between but DM affected diet. Diets amount produced, its (%) non-removed faeces (g DM/kg feed). The highest lowest observed FM BGP respectively. Accordingly, resulted (37 g feed), while (125 feed) faeces. Additionally, it also that differences can compensate variation produced. Consistent with data, PSD influenced diets. MM proportion particles <40 μm size, had largest this range. Furthermore, ingredient composition evident stability faeces, producing most stable, whereas CON, SCP resulting relatively unstable pellets. In addition, due to inclusion level nutrients their corresponding digestibility, chemical Overall, showed influences is an important factor determining efficiency, PSD, trout.

As the global demand for aquaculture products continues to rise, sustainable and efficient feed sources are crucial industry's growth. Insects have emerged as a promising alternative due their high nutritional content, low environmental impact, potential alleviate overreliance on conventional ingredients. This abstract delves into role of insects in aquaculture, elucidating benefits challenges. offer rich source fats, minerals, proteins, vitamins that meet dietary requirements various aquatic species. Their rapid growth rates ability thrive organic waste contribute eco-friendly nature, reducing burden associated with aqua-feed production. Notably, can be reared substrates, minimizing competition arable land demands wild fish hoards utilized fishmeal construction. However, integrating presents certain hurdles. Standardized production methods, quality control, regulatory frameworks need established ensure consistent safe insect-derived feed. Additionally, understanding impacts insect-based diets health, growth, product is vital. It conclusion hold immense addressing while challenges through collaborative researcher research, sector.
