Due to the limited application of insect meal in giant freshwater prawn (Macrobrachium rosenbergii) culture, present study aimed (i) produce spirulina-enriched full-fat black soldier fly (Hermetia illucens) prepupae (HM) and (ii) test, for first time, two experimental diets characterized by 3% or 20% fish oil replacement with HM (HM3 HM20, respectively) on M. rosenbergii post-larvae during a 60-day feeding trial conducted aquaponic systems. The did not negatively affect survival rates...
By answering the need for increasing sustainability in aquaculture, present study aimed to compare growth, gene expression involved appetite regulation, physical characteristics, and chemical composition of Sparus aurata fed alternative protein sources. Fish were ten iso-proteic, iso-lipidic, isoenergetic diets: a vegetable-based (CV) marine ingredient-rich (CF) diet set as control diets. The others prepared by replacing graded levels (10, 20 or 40%) vegetable proteins CV with from...
This study compared the nutrient-energy retention, digestive function, growth performance, and welfare of rainbow trout (ibw 54 g) fed isoproteic (42%), isolipidic (24%), fishmeal-free diets (CV) over 13 weeks. The consisted plant-protein replacement with graded levels (10, 30, 60%) protein from poultry by-product (PBM) black soldier fly H. illucens pupae (BSFM) meals, either singly or in combination. A fishmeal-based diet was also tested (CF). Nitrogen retention improved moderate high...
Shearing to improve heat dissipation is common in sheep farming. This study evaluated the influence of shearing on thermoregulatory responses crossbred from adapted breeds exposed stress. Ten ewes were kept a climate chamber stress (10–13 h), reaching 37 ± 1.0 °C for nine days, during two consecutive periods, without shearing, and then at 14 days after evaluating all variables. Rectal temperature, respiration rate, sweating ocular surface skin temperature analyzed 7, 10, 13, 17, 20 h, blood...
RESUMO: Desmama é uma fase crítica na vida do suíno devido a separação materna e introdução de dieta seca. A termografia infravermelha medida região ocular se mostra como um indicador confiável para condição estresse pontual suínos. O objetivo deste estudo foi determinar relação entre medidas da superfície cortisol em situações leitões pós desmama. Foram avaliados 66 leitões, vez por semana, durante sete semanas, dois períodos dia (7h 15h) com temperatura superficial ocular, dorso amostras...
This study investigates the combined effect of progressive or abrupt weaning after stress during middle and late pregnancy on performance development lambs. Twenty-four male lambs were used, born from 18 Santa Ines ewes that divided into three experimental groups. Pregnant submitted to application Lipolysaccharides E. coli (LPS) 70th day (Ig; n=12) at 120th (Fg; n=8). Animals kept as control (Cg; n=14). Lambs in a 6-day interval subjected two types (Pw: weaning; Aw: 45 days age). Lamb data,...
The potential of insects as alternative ingredients in animal feeds has already been established. However, limited information is available concerning the use insect oils lipid sources for aquafeeds. Therefore, a trial was conducted to assess effects inclusion black soldier fly (Hermetia illucens) larvae oil (HIO) diets gilthead seabream (Sparus aurata) juveniles. Four (45% crude protein, 18% lipids) were formulated replace vegetable (VO) blend (50% linseed, 30% palm, and 20% rapeseed oil)...
Protein meals from insects in combination with poultry by-product meal appear to be promising ingredients for replacing conventional proteins the diets of carnivorous fish. The present study explored effects on growth performance, hepatic enzymatic activity, and fillet physical nutritional characteristics during a 66-day feeding trial performed European seabass. A total 3000 fish were distributed into three tanks, where control group was fed commercial diet (CG) second duplicate experimental...
The invasive blue crab is challenging the Mediterranean basin, progressively declining local populations. This reflects a lower prey availability and suitability of dietary nutrients (mainly n-3 polyunsaturated fatty acids, PUFA). present study aimed to challenge males females with feed source low in PUFA respect one showing proper acid profile investigate responses terms growth, welfare, lipid characterization target tissues, reproductive status. Blue crabs were divided into three groups as...

Consumer interest in safeguarding animal welfare and increased demand for fresh aquatic products support the need to understand effects of stunning methods used aquaculture on biochemical process affecting fish fillet quality. The present paper aimed at comparing electrical (ES) cold shock (ICE) Salmo carpio, an Italian endemic under-investigated species. Rigor mortis evolution, adenosine 5'-triphosphate (ATP), shape, colour, pH water holding capacity were assessed by integrating chemical...
