“…The use of protein hydrolysates for animal feed have favourable formulation properties, such as a high solubility over a wide pH range and ionic strengths, and a set of positive nutritional properties, including feeding stimulation and palatability enhancement, facilitated adsorption of e.g. labile and insoluble amino acids, and lastly, presence of beneficial hormone-like peptides [72]. As mentioned, feed production is an area surrounded by a strict regulatory framework, and it has recently been published a relevant review of the European regulatory framework and potential uses of ABPs for feed [73].…”

“…From a global life cycle perspective, this could perhaps be better utilised. New technology in marine ingredient processing, such as advanced enzymatic hydrolysis techniques, is enabling more efficiency and synergistic effects with other ingredients, through providing more advanced nutritional profiles than raw ingredients are able (Martínez-Alvarez et al 2016). This has undoubted opportunities for the salmon aquaculture industry to improve its by-product utilisation strategy.…”

Purpose The European Union relies on seafood imports to supply growing demand that European production has failed to meet. Politically motivated media reports have denigrated competing imports in favour of local production. While life cycle assessment (LCA) measures global impact of value chains, it often fails to contextualise them. Using LCA, this article takes farmed Scottish Atlantic salmon as a case study of Blocal^production to identify and map the contributions to global environmental impact. Methods Data on the Scottish salmon value chain were collected by structured survey from a large international feed mill, six farms and a major processor. Secondary data were collected from available literature on feed ingredients and background data from EcoInvent2.2. A mid-point CML2001 approach was adopted focussing on global warming potential (GWP), acidification potential (AP), eutrophication potential, ozone depletion potential, photo-chemical oxidation potential, consumptive water use and land use. Results were displayed as contribution analyses of materials and processes and mapped geographically using area plots. Results and discussion Far from being a Blocally^produced commodity, nearly 50% of the feed ingredients were sourced from South America and less than 25% originated in the UK.It was found that over 90% of the impact to farm-gate was embodied in feed, apart from eutrophication potential which was high at the farm from direct nitrogenous emissions into the marine environment. The majority of impacts do not occur in Scotland, particularly for land and water use, which occur at a more geographically significant level than GWP or AP, which are more global or regional impacts, respectively. High GWP emissions from vegetable-based ingredients were related to soil management and energy intensive processes such as wet milling to produce gluten from wheat and maize, sunflower and rapeseed oil processing. Conclusions The results show that in an age of globalised commodity trading, concerns around Blocal^production are often misleading. As consumers try to make more responsible purchase choices, they may be misled over the global impacts their choices are having. There are clearly trade-offs between different feed ingredients, especially regarding substitution of marine ingredients with those of vegetable origin. While marine ingredients perform comparatively well, they are highly limited, and biodiversity impacts of different ingredients are less clear and difficult to compare.

“…The immunostimulatory effects of fish hydrolysate protein may contribute to the control of diseases that devastate fish farming (Murray et al 2003;Martínez-Alvarez, Chamorro, & Brenes, 2015) in a practical way by the inclusion in diets (Bui et al, 2014), reducing the use of chemicals that are difficult to implement and bear high environmental impact.…”

ABSTRACT. This study aimed to evaluate the digestibility of tilapia by-product protein hydrolysate powder (TBHP) from tilapia filleting by-product, and its inclusion in diets for Nile tilapia larvae. In order to determine the apparent digestibility coefficients, two diets were formulated, the reference diet and the test diet (20% of TBHP) and, to evaluate the inclusion, six diets were formulated, which were with 0.0, 2.0; 4.0; 6.0, and 8.0% of TBHP. The apparent digestibility coefficients of crude protein and gross energy were 89.5 and 98.3%, respectively. At levels above 4.0% of inclusion of TBHP, the weight, final length and weight gain were impaired, however, survival rate was higher (p < 0.05). The TBHP can be used in diets for tilapia due to the high digestibility coefficients for crude protein and gross energy. The inclusion of up to 4.0% of TBHP does not affect the reproductive performance and survival rate of Nile tilapia larvae.Keywords: digestibility, fish nutrition, performance.Hidrolisado proteico seco do resíduo da filetagem de tilápias em dietas para larvas de tilápia do Nilo RESUMO. Objetivou-se avaliar a digestibilidade do hidrolisado proteico seco do resíduo da filetagem de tilápias (HPST) e sua inclusão em dietas para larvas de tilápia do Nilo. Para determinar os coeficientes de digestibilidade aparente, duas dietas foram elaboradas, referência e teste (com 20% do HPST) e para avaliação da inclusão, seis dietas foram formuladas com 0,0, 2,0; 4,0; 6,0, e 8,0% de HPST. Os coeficientes de digestibilidade aparente da proteína e energia bruta foram de 89,5 e 98,3%, respectivamente. Nos níveis acima de 4,0% de inclusão de HPST o peso e comprimento final e ganho em peso foram prejudicados, no entanto a sobrevivência foi maior (p < 0,05). O HPST pode ser utilizado em dietas para tilápias em função dos elevados coeficientes de digestibilidade para proteína bruta e energia bruta. A inclusão de até 4,0% de HPST não afeta o desempenho produtivo e a sobrevivência de larvas de tilápias do Nilo.Palavras-chave: digestibilidade, nutrição de peixes, desempenho.
