“…Many studies have shown the importance and effects of levels, and source and forms of protein in the feed on adult fish growth and physiology (Abdelghany, 2003; Failla et al, 2006; Ostaszewska et al, 2010; Kumar et al, 2012; Goosen et al, 2014). Zambonino Infante et al (1997) showed that replacement of 20% of the fish meal in the fish diet with fish meal hydrolysate (75% di-tri peptide) significantly improved growth performance, increased proteolytic capacity of the pancreas, and affected intestinal enzymes activity in European sea bass larvae.…”

Peptide Transporters in the Primary Gastrointestinal Tract of Pre-Feeding Mozambique Tilapia Larva

Fish larvae differ greatly from the adult form in their morphology and organ functionality. The functionality of the gastrointestinal tract depends on the expression of various pumps, transporters, and channels responsible for feed digestion and nutrients absorption. During the larval period, the gastrointestinal tract develops from a simple closed tube, into its complex form with differentiated segments, crypts and villi, as found in the adult. In this study, we characterized the expression of three peptide transporters (PepT1a, PepT1b, and PepT2) in the gastrointestinal tract of Mozambique tilapia ( Oreochromis mossambicus ) larvae along 12 days of development, from pre-hatching to the completion of yolk sac absorption. Gene expression analysis revealed differential and complimentary time-dependent expression of the PepT1 variants and PepT2 along the larval development period. Immunofluorescence analysis showed differential protein localization of the three peptide transporters (PepTs) along the gastrointestinal tract, in a similar pattern to the adult. In addition, PepT1a was localized in mucosal cells in the larvae esophagus, in much higher abundance than in the adults. The results of this study demonstrate specialization of intestinal sections and absorbance potential of the enterocytes prior to the onset of active exogenous feeding, thus pointing to an uncharacterized function and role of the gastrointestinal tract and its transporters during the larval period.

“…In white shrimp, diets supplemented with 10% FPH, represented by cooked (heads, fins, skin, dark muscle meat) and fresh (viscera) by-products obtained from tuna processing, improved the protein digestibility and performances in the juveniles (Hernandez et al 2011). In abalone, a low FPH inclusion, amounting to 6 g/kg protein in the final diet, improved cellular immunity and growth (Goosen et al 2014). In young pigs, FPH, derived from farmed salmon and added to diet fulfilling all the nutrient recommendations for young stage, gave equal growth results and greater feed intake in comparison to soy protein concentrate (Norgaard et al 2012).…”

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 that highlights the need for sustainable development of animal production, the alternative protein sources are discussed. In particular, after providing some indications on their production and supply focussing on EU, a SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis was performed to identify the key factors that could help or impair the development of both protein sources production sectors. Finally, future perspectives are presented. The use of processed animal proteins derived from insects in farmed fish feeding is recognised by the EU legislation that authorises the use of proteins from seven insect species and the allowed substrates to rear insects. Insects have several advantages in nutritional value and the amino acid composition of their proteins generally meet animal requirements for good growth and health. The SWOT analysis indicated that insect meals can be considered as feed functional ingredients with beneficial properties that depend on the insect species, rearing system adopted, and the substrate used for their growth. Insects are expected to be increasingly used as a replacement for conventional animal-derived proteins, especially in aquafeeds. In the section regarding fishery and aquaculture by-products, the potential use of raw materials obtained during seafood processing is discussed. Peptides and amino acids recovered from as hydrolysed proteins can be used in animal feeds to partially substitute conventional protein feedstuffs thus providing nutrients, bioactive compounds and feed additives for animals. The SWOT analysis identified opportunities and weaknesses. Both the alternative protein sources are promising alternative feed ingredients for livestock production. HIGHLIGHTSThe sustainable development of animal production sector needs alternative protein sources for feeds formulation. Insects and fishery-and aquaculture by-products represent optimal alternative protein sources. A SWOT analysis has identified the key factors for the development of both protein sources production sectors. ARTICLE HISTORY

Introducción. Los subproductos de la industria pesquera representan más del 50 % de la materia prima y suelen utilizarse para generar productos de bajo valor agregado. Sin embargo, estos subproductos presentan componentes con un alto valor comercial como los aceites ricos en omega 3, proteínas de alto valor nutricional, colágeno, enzimas y péptidos bioactivos. Objetivo. Presentar el estado actual respecto a la funcionalidad y el proceso de obtención de hidrolizados proteicos y péptidos bioactivos de origen pesquero. Desarrollo. Este trabajo se realizó en Costa Rica entre enero de 2017 y setiembre de 2019, en él se describe la generación y utilización de los subproductos de la industria pesquera, el proceso de obtención de hidrolizados y péptidos, desde las etapas preliminares hasta su fraccionamiento y purificación; finaliza con las aplicaciones y propiedades funcionales de estos compuestos como su valor nutricional, capacidad de retención de agua, emulsificante y espumante y su actividad antioxidante y antihipertensiva. Conclusión. Los hidrolizados proteicos y los péptidos de origen pesquero son una opción para la creación de nuevos ingredientes con aplicaciones en la industria alimentaria y farmacéutica, especialmente por su actividad antioxidante y antihipertensiva, propiedades que dependen del fraccionamiento y purificación de los péptidos bioactivos, por lo que se deben desarrollar y optimizar las tecnologías que permitan realizar estos procesos a nivel industrial y a un costo adecuado.
