Insects as a feed ingredient for fish culture: Status and trends

Aquaculture and Fisheries, Journal Year: 2021, Volume and Issue: 7(2), P. 166 - 178

Published: Nov. 9, 2021

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. We also discussed feeds with listed future research directions make green, profitable (GPS) aquaculture. It certain that near future, large-scale farming processing produce ingredient will positive impact sustainability profitability

Evaluation of Probiotic Effects on the Growth Performance and Microbiome of Nile Tilapia (Oreochromis niloticus) in a High‐Density Biofloc System

Aquaculture Nutrition, Journal Year: 2025, Volume and Issue: 2025(1)

Published: Jan. 1, 2025

Biofloc technology is an aquaculture production system that has gained popularity with tilapia production. Probiotics provide benefits for the host and/or aquatic environments by both regulating and modulating microbial communities their metabolites. When a probiotic feed combined biofloc system, amount may be improved through better fish growth, disease resistance, water quality reducing organic matter stabilizing metrics such as pH components of nitrogen cycle. Two research trials measured Nile ( Oreochromis niloticus ) growth performance composition in within fecal material, following feeding top‐coated treatments. Trial A incorporated (71.4 ± 4.4 g), commercial diet (Control) was top coated either Bacillus velenzensis AP193 (AP193; 1 × 10 7 CFU g BiOWiSH Feedbuilder Syn3 (BW; 3.6 4 −1 ). In B, juvenile (5.34 0.42 g) were fed treatment diets two different concentrations at final (BWx1) 7.2 (BWx2). Tilapia offered (38% protein floating feed) control trials. Results from indicated no differences due to additions, except conversion ratio (FCR) B. Both BWx1 BWx2 showed survival, quality, solids management, bacterial matter. Even though results presented significant differences, could differ based on concentration, route administration, or impact community culture water. testing larger scale varied doses necessary achieve effective dosage improving performance.

Fishmeal Dietary Replacement Up to 50%: A Comparative Study of Two Insect Meals for Rainbow Trout (Oncorhynchus mykiss)

Animals, Journal Year: 2022, Volume and Issue: 12(2), P. 179 - 179

Published: Jan. 12, 2022

The demand of optimal protein for human consumption is growing. Food and Agriculture Organization (FAO) has highlighted aquaculture as one the most promising alternatives this supply gap due to high efficiency fish growth. However, been facing its own sustainability problem, because traditionally satisfied with use fishmeal (FM) main source. Some sustainable substitutes FM come from insects. present manuscript provides insight into an experiment carried out on rainbow trout (Oncorhynchus mykiss) a 50% replacement different larvae insect meals: Hermetia illucens (HI), Tenebrio molitor (TM). TM showed better results growth, utilization more active digestive function, supported by intestinal histological changes. Liver histology intermediary metabolism did not show relevant changes between meals, while other parameters such antioxidant enzyme activities tissue damage indicators potential meals functional ingredients.

Edible Insects: A New Sustainable Nutritional Resource Worth Promoting

Foods, Journal Year: 2023, Volume and Issue: 12(22), P. 4073 - 4073

Published: Nov. 9, 2023

Edible insects are a highly nutritious source of protein and enjoyed by people all over the world. Insects contain various other nutrients beneficial compounds, such as lipids, vitamins minerals, chitin, phenolic antimicrobial peptides, which contribute to good health. The practice insect farming is far more resource-efficient compared traditional agriculture animal husbandry, requiring less land, energy, water, resulting in significantly lower carbon footprint. In fact, 12 25 times efficient than animals converting low-protein feed into protein. When it comes production per unit area, only requires about one-eighth land needed for beef production. Moreover, generates minimal waste, can consume food biomass that would otherwise go contributing circular economy promotes resource recycling reuse. be fed with agricultural unused plant stems scraps. Additionally, excrement produced used fertilizer crops, completing chain. Despite undeniable sustainability nutritional benefits consuming insects, widespread acceptance incorporating our daily diets still has long way go. This paper provides comprehensive overview value edible development processing technologies, problems faced marketing products foods improve reference how choose insects.

Plastic pollution is one of the biggest current global threats to environment given that petroleum-based plastic recalcitrant and can stay in for decades, even centuries, depending on specific type. Since less than 10% all made recycled, other solutions (such as incineration or landfill storage) are pollutant methods, new, environmentally friendly needed. In this regard, latest biotechnological discovery topic capability insect larvae use polymers carbon feedstock. This present review describes most relevant information capable degrading plastic, mainly Galleria mellonella (Fabricius, 1798), Tenebrio molitor (Linnaeus, 1758), Zophobas atratus 1776), also adds new about commonly studied “plastivore” insects such termites. covers literature from very first work describing degradation by published 2014 way research available (till June 2024), focusing identification a wide variety plastic-degrading microorganisms isolated guts understanding potential molecular mechanisms take place.
