“…Differences can be attributed to environmental conditions because the vastness of the Prut hydrographic basin, permanent water stream, and lower feed quantity versus the environment provided by the farm influence, as was demonstrated, a growth rhythm. The obtained values fell within the literature limits [55,56].…”

Quantitative and qualitative flesh production in the Silurus glanis species was comparatively studied between two fish groups: one from aquaculture (AG) and the other from a natural environment, the Prut River (RG). Morphometry was carried out on the fish, and then biometric and conformational indices were calculated. Better values were found in the aquaculture catfish. The Fulton coefficient was 0.82 in the Prut River fish and 0.91% in the farmed ones. The fleshy index reached 19.58% in the AG fish and 20.79% in the RG fish, suggesting better productive capabilities in the AG fish. Postslaughter, the flesh yield and its quality were assessed at different moments throughout the refrigeration period (0–15 days), and chemical compound loss occurred. In the AG samples, the water content decreased by 8.87%, proteins by 27.66%, and lipids by 29.58%. For the RG samples, the loss reached 8.59% in water, 25.16% in proteins, and 29%in lipids. By studying the fatty acids profile and sanogenic indices, good levels of PUFA (31–35%) were found, and the atherogenic index reached 0.35–0.41 while the thrombogenic index ranged between 0.22 and 0.27. Consequently, it can be stated that fish origin and especially the refrigeration period influence the flesh proximate composition and nutritional value of European catfish.

“…In the same study, there were also no differences in the water and ash content, the only significant variation being recorded in the total n-6, which increased from 7.7 to 9.98. Similarly, the use of DDGS in the diet of different species (catfish and rainbow trout) did not produce significant changes in meat composition [ 42 , 43 ].…”

Distillers dried grains with solubles (DDGS), a coproduct from the ethanol production industry, is successfully used as an ingredient in feeding cattle and pigs due to its relatively high protein and nutrient content and low price compared to cereals. The aim of this study was to establish the optimal DDGS concentration that can be included in the diet of common carp. A seven-week experiment was performed on common carp with an initial weight of 86 g feed with three experimental diets D0 (DDGS 0%), D1 (DDGS 25%) and D2 (DDGS 35%). The chemical composition of DDGS analyzed by Fourier Transform Near-Infrared (FT-NIR) spectroscopy showed a protein content of 27.56% and oil at 6.75%. Diets with DDGS did not produce significant changes in growth parameters, flesh quality, and blood biochemical profile. Regarding the oxidative status in the muscle tissue, D1 and D2 significantly reduced, in a dose-dependent manner, the specific activity of SOD and GSH, while CAT and GPX were left unaffected. In the liver tissue, CAT, GSH, MDA and carbonylated proteins were reduced in the DDGS diets. The microbiological analysis of the intestinal contents revealed a variation in microbial density depending on the diet used. The total number of aerobic germs was between 224.2 × 104 and 69.84 × 106 (D2 > D1 > D0) and the total number of anaerobic germs was between 15.2 × 102 and 28.2 × 102 (D2 > D0 > D1).

“…Four different feeds for African catfish were produced at the Institute of Food Technology (University of Novi Sad, Novi Sad, Serbia) for digestibility trials of three different insect meals. For this purpose, a control feed (reference) was formulated, which was then mixed individually with the test ingredients at a 70 : 30 ratio (control: test, as is basis) to produce the experimental diets [40][41][42][43] and were then extruded. The control feed was prepared to be a high fish meal diet in order to be easily digestible for fish.…”

A digestibility trial was conducted with African catfish hybrid juveniles in order to determine the apparent digestibility coefficients (ADCs) of different nutrients. The experimental diets contained defatted black soldier fly (BSL), yellow mealworm (MW), or fully fat blue bottle fly (BBF) meals, in a 70 : 30 ratio between the control diet and the tested insect meals. The indirect method for the digestibility study was performed using 0.1% yttrium oxide as an inert marker. Fish juveniles of 217.4 ± 9.5 g initial weight were distributed in 1 m3 tanks (75 fish/tank) of a recirculating aquaculture system (RAS), in triplicates, and fed until satiation for 18 days. The average final weight of the fish was 346 ± 35.8 g . The ADCs of the dry matter, protein, lipid, chitin, ash, phosphorus, amino acids, fatty acids, and gross energy for the test ingredients and diets were calculated. A six-month storage test was carried out to evaluate the shelf life of the experimental diets, while the peroxidation and microbiological status of the diets were also assessed. The ADC values of the test diets differed significantly ( p < 0.001 ) compared to those of the control for most of the nutrients. Altogether, the BSL diet was significantly more digestible for protein, fat, ash, and phosphorus than the control diet but less digestible for essential amino acids. Significant differences were found between the ADCs of the different insect meals evaluated ( p < 0.001 ) for practically all nutritional fractions analyzed. The African catfish hybrids were able to digest BSL and BBF more efficiently than MW, and the calculated ADC values agreed with those of other fish species. The lower ADCs of the tested MW meal correlated ( p < 0.05 ) with the markedly higher acid detergent fiber (ADF) levels present in the MW meal and MW diet. Microbiological evaluation of the feeds revealed that mesophilic aerobic bacteria in the BSL feed were 2–3 orders of magnitude more abundant than those in the other diets and their numbers significantly increased during storage. Overall, BSL and BBF proved to be potential feed ingredients for African catfish juveniles and the shelf life of the produced diets with 30% inclusion of insect meal retained the required quality during a six-month period of storage.
