“…Using species-specific fishmeal and fish oil yields 27 , we calculated that Norway’s salmon sector fish oil and fishmeal usage in 2020 required 2,111,283 t of whole fish to be reduced into marine feeds (Fig. 1a and Supplementary Table 1 ).…”

“…For example, the processing of mackerel currently used for ECM would supply 47,321 t of usable nutrient-dense by-products, such as skin, viscera, heads and bones 27 . Marine ingredients from by-products are generally considered to be less environmentally impacting than those from whole fish because of the historical high wastage of fish by-products 23 , 26 , 27 , 59 , 60 , and full by-product utilization can potentially more than replace whole fish required for current fishmeal and oil production 61 . Consequently, upcycling by-products from edible seafood processing for use in feeds is essential from both nutritional and environmental perspectives.…”

“…Consequently, upcycling by-products from edible seafood processing for use in feeds is essential from both nutritional and environmental perspectives. In 2022, around 35% of fishmeal and fish oil was produced from processing by-products (an increase from 8% in 2000) 27 , suggesting that increased by-product utilization is already helping the transition towards resource-efficient food systems 62 .…”

“…In 2020, Norway produced 1,467,655 t of Atlantic salmon, using 203,597 t of fish oil and 239,711 t of fishmeal 65 . Using species-specific estimates for fishmeal and fish oil yields from whole fish and trimmings 27 , we estimated the total volume of whole fish required to produce Norwegian salmon in 2020, based on fishmeal and fish oil usage (Supplementary Table 1 ). These values were then combined with feed species composition estimates from a major feed producer 27 , 68 to estimate the volume of each fish species reduced into fishmeal and fish oil (Supplementary Table 2 ).…”

Wild fish used as aquafeeds could be redirected towards human consumption to support sustainable marine resource use. Here we use mass-balance fish-in/fish-out ratio approaches to assess nutrient retention in salmon farming and identify scenarios that provide more nutrient-rich food to people. Using data on Norway’s salmon farms, our study revealed that six of nine dietary nutrients had higher yields in wild fish used for feeds, such as anchovies and mackerel, than in farmed salmon production. Reallocating one-third of food-grade wild feed fish towards direct human consumption would increase seafood production, while also retaining by-products for use as aquafeeds, thus maximizing nutrient utilization of marine resources.

“…Marine ingredients are highly important in aquatic feed to provide macro- and micro-nutrients and organoleptic properties, enhancing the digestibility and growth performance of formulated diets. Marine ingredients used in aquafeed are usually meals and oils rendered by small pelagic fish, and by-products of fish and seafood processing [ 6 ]. Fish meal is considered the most valuable protein source, due to its exceptional benefits including its well-balanced composition of amino acids, good digestibility, and palatability, as well as its enhancement of the digestion, and absorption of nutrients in fish diets [ 7 ].…”

Recent Advances in Mycotoxin Determination in Fish Feed Ingredients

et al. 2023

View full text Add to dashboard Cite

Low-cost plant-based sources used in aquaculture diets are prone to the occurrence of animal feed contaminants, which may in certain conditions affect the quality and safety of aquafeeds. Mycotoxins, a toxic group of small organic molecules produced by fungi, comprise a frequently occurring plant-based feed contaminant in aquafeeds. Mycotoxin contamination can potentially cause significant mortality, reduced productivity, and higher disease susceptibility; thus, its timely detection is crucial to the aquaculture industry. The present review summarizes the methodological advances, developed mainly during the past decade, related to mycotoxin detection in aquafeed ingredients, namely analytical, chromatographic, and immunological methodologies, as well as the use of biosensors and spectroscopic methods which are becoming more prevalent. Rapid and accurate mycotoxin detection is and will continue to be crucial to the food industry, animal production, and the environment, resulting in further improvements and developments in mycotoxin detection techniques.
