“…Recently, PBM [47][48][49][50][51] and insect meal [52,53] were tested as alternative ingredients for seabream diet formulation with promising results in terms of zootechnical parameters, fish health, and fillet quality, while scarce information is so far available about the effects of these ingredients on the fish intestine and liver response. In addition, in the previous experiments, PBM and insect meal were tested as an FM substitute, while the effect of their inclusion on a vegetable-based diet, singly or in combination, is still unknown in gilthead seabream.…”

The attempt to replace marine-derived ingredients for aquafeed formulation with plant-derived ones has met some limitations due to their negative side effects on many fish species. In this context, finding new, sustainable ingredients able to promote fish welfare is currently under exploration. In the present study, poultry by-products and Hermetia illucens meal were used to replace the vegetable protein fraction in diets totally deprived of fish meal intended for gilthead seabream (Sparus aurata). After a 12-week feeding trial, a multidisciplinary approach including histological, molecular, and spectroscopic techniques was adopted to investigate intestine and liver responses to the different dietary formulations. Regardless of the alternative ingredient used, the reduction in dietary vegetable proteins resulted in a lower incidence of intestine histological alterations and inflammatory responses. In addition, the dietary inclusion of insect meal positively affected the reduction in the molecular inflammatory markers analyzed. Spectroscopic analyses showed that poultry by-product meal improved lipid absorption in the intestine, while insect meal induced increased liver lipid deposition in fish. The results obtained demonstrated that both poultry by-products and H. illucens meal can successfully be used to replace plant-derived ingredients in diets for gilthead seabream, promoting healthy aquaculture.

“…properties that affect the appetite of fish (Han et al., 2019), and the palatability of feed used in aquaculture practices is very important. Various stimulants and attractants are widely applied to contribute this feature to feeds, particularly in scientific studies where vegetable protein sources are used as alternatives in fish feeds (Al‐Souti et al., 2019). For instance, it is stated that krill meal is used as a chemoattractant in shrimp diets (Saleh et al., 2018), fish silage in white pacific shrimp diets, whereas amino acids such as alanine, hydroxyproline, phenylalanine, leucine, partially proline and nucleotides are considered as chemoattractants for rainbow trout (Kohbara & Caprio, 2001; Marui et al., 1983).…”

“…It is known that fish have the ability to differ the taste of chemical substances (Kasumyan & Mouromtsev, 2020), therefore it is important to observe the taste preferences of these animals so that, increasingly, studies are carried out to include foods/ingredients that can act as growth producers and improve the health of the animal, since more attractive and palatable foods can increase the consumption of the offered diets (Al-Souti et al, 2019;Jingting et al, 2020;Yang et al, 2020).…”

Este trabalho teve como objetivo avaliar a inclusão do hidrolisado de mucosa suína (HMS) como estimulante de consumo em dietas para juvenis de tilápias. Para isso, foram utilizados 12 juvenis de tilápias, distribuídos em 12 aquários, onde foram realizadas gravações em vídeo para obter dados de atratividade e palatabilidade: (a) tempo de captura do primeiro pélete; (b) rejeição dos péletes pela tilápia; (c) aproximação sem ingestão; (d) percentual de ingestão; (e) tempo que a tilápia levou para consumir todos os péletes. Foram avaliados seis tratamentos em relação ao controle, sendo eles sem inclusão de HMS e de um a cinco por cento de inclusão do HMS. O tratamento com 1% de inclusão apresentou a maior ingestão dos péletes, e as demais variáveis não diferenças entre os tratamentos avaliados, porém em comparação com o controle, houve uma redução maior no consumo do tratamento com 3% de inclusão. Deste modo, sugere-se a inclusão de 1% do HMS para melhorar a palatabilidade da ração ofertada.
