Insect and fish by-products as sustainable alternatives to conventional animal proteins in animal nutrition

Italian Journal of Animal Science, Journal Year: 2020, Volume and Issue: 19(1), P. 360 - 372

This paper reviews current knowledge on two feedstuffs, that is, insect meal and fish by-products, as alternatives to conventional animal protein sources. After an introductory part highlights the need for sustainable development of production, alternative sources are discussed. In particular, after providing some indications their production supply focussing EU, a SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis was performed identify key factors could help or impair both sectors.

Replacement of Fish Meal by Black Soldier Fly (Hermetia illucens) Larvae Meal: Effects on Growth, Haematology, and Skin Mucus Immunity of Nile Tilapia, Oreochromis niloticus

Animals, Journal Year: 2021, Volume and Issue: 11(1), P. 193 - 193

Published: Jan. 15, 2021

Fish meal (FM) is no longer a sustainable source for the increasing aquaculture industry. Animal proteins from insects may be used as FM alternative long they do not create adverse effects in fish. Black soldier fly larvae (BSFLM) was tested 12-week experiment on Nile tilapia (Oreochromis niloticus). Four hundred and twenty (14.77 ± 2.09 g) fish were divided into seven groups fed diets: control (0% BSFLM-100% FM), replaced by BSFLM at rates of 10%, 20%, 40%, 60%, 80% 100%. Growth indexes, feed utilization efficiency indices, intake, survival rate significantly different (p > 0.05) between Values red blood cell, white cells, hemoglobin, hematocrit, mean corpuscular volume hemoglobin concentration, cell distribution width, platelet values affected BSFLM. Skin, mucus lysozyme, peroxidase activities improved can substitution (O. niloticus) diet up to 100% with effects.

Alternative Proteins for Fish Diets: Implications beyond Growth

Animals, Journal Year: 2022, Volume and Issue: 12(9), P. 1211 - 1211

Published: May 7, 2022

Aquaculture has been challenged to find alternative ingredients develop innovative feed formulations that foster a sustainable future growth. Given the most recent trends in fish formulation on use of protein sources decrease dependency fishmeal, it is fundamental evaluate implications this new paradigm for health and welfare. This work intends comprehensively review impacts novel dietary gut microbiota health, stress immune responses, disease resistance, antioxidant capacity. The research results indicate sources, such as terrestrial plant proteins, rendered animal by-products, insect meals, micro- macroalgae, single cell proteins (e.g., yeasts), may negatively impact thus affecting responses. Nevertheless, some insects algae have functional properties exert an immunostimulatory activity. Further effects beyond growth, clearly needed. information gathered here utmost importance, order diets guarantee production healthy with high quality standards optimised welfare conditions, contributing growth aquaculture industry.

Salmon gut microbiota correlates with disease infection status: potential for monitoring health in farmed animals

Animal Microbiome, Journal Year: 2021, Volume and Issue: 3(1)

Published: April 20, 2021

Infectious diseases cause significant production losses in aquaculture every year. Since the gut microbiota plays an essential role regulating host immune system, health and physiology, altered compositions are often associated with a diseased status. However, few studies have examined association between disease severity degree of dysbiosis, especially when is not site primary infection. Moreover, there lack knowledge on whether bath treatment formalin, disinfectant commonly used to treat external infections, might affect microbiome as consequence formalin ingestion.

Abstract The aims of this review are to describe the role ‘blue‐food production’ (animals, plants and algae harvested from freshwater marine environments) within a circular bioeconomy, discuss how such framework can help sustainability resilience aquaculture summarise key examples novel nutrient sources that emerging in field fed‐aquaculture species. Aquaculture now provides >50% global seafood supply, share is expected increase at least 60% next decade. an important tool for reducing resource consumption protein production increasing climate change other disruptions (i.e. pandemics, geo‐political instability). Importantly, blue foods also provide essential nutrition growing human population. Blue helping goal ‘zero hunger’ (United Nation's Sustainable Development Goal 2) while dependency on finite natural resources but further refinement new solutions needed make industry more ‘circular’ sustainable, particularly with respect sourcing raw materials aquafeeds.

Abstract With the continuous growth of human population and associated need for high‐quality protein, aquaculture sector will be required to increase significantly in productivity. This productivity achieved through more efficient use resources like feeds, genetic improvement limiting impacts disease. One key links between animal disease is that microbial diversity, with high‐throughput sequencing technologies increasing our understanding role microorganisms play health, development physiology vertebrate invertebrate hosts alike. Increasing microbial–host interactions help avoid or manage dysbiosis systems final aim improving We review current literature, which indicates there an association diversity systems, as changes bacterial microbiomes are implicated performance, both viral origin, triggered by environmental stressors diet choice. Dysbiosis, whether form loss beneficial bacteria, expansion pathogens potentially harmful microorganisms, can used indicator tool monitoring purposes.
