“…In the next few years, there will be an increase in the global demand of protein because of the constant increase in the world population [ 1 ]. Aquaculture has the fastest growing in the food production, with an average annual rate above 5.5% per year [ 2 ] and, for this reason, is considered as one of the livestock sectors able to support the global demand of animal products [ 3 ].…”

Background Recent investigations highlighted that Hermetia illucens (BSF) larva meal can be a valuable alternative protein source for aquafeed production. In this study, in substitution of fishmeal, we used increasing inclusion levels of a partially defatted BSF larva meal in low fishmeal-based diets for rainbow trout (Oncorhynchus mykiss Walbaum) and we evaluated the related implications in terms of growth performance, physical characteristics, proximate and fatty acid (FA) compositions of the fillets, gut and liver histology, and diet digestibility. In a 131-day trial, 576 fish (100.1 ± 9.29 g) were randomly allotted to 24 tanks (24 fish/tank, 4 replicates/treatment). Six experimental diets were produced to have partial replacement of fishmeal (0, 10%, 20%, 30%, 40% and 50%) by increasing levels of BSF meal (0% [BSF0], 3% [BSF3], 6% [BSF6], 9% [BSF9], 12% [BSF12] and 15% [BSF15] on as fed basis, respectively). Results No differences were observed among the treatments for all the considered growth performance parameters. The viscero and hepato-somatic indexes showed significant differences among the treatments, with the highest values observed in the BSF15 group. No differences were recorded in terms of fillet’s physical characteristics, dry matter (DM), crude protein (CP) and ether extract (EE) contents. Total saturated and monounsaturated FA increased, while polyunsaturated FA (particularly n-3 FA) decreased while increasing the HI meal inclusion in the diet. Histopathology of liver and gut was not affected, whereas, in posterior gut, villi were higher in BSF6 and BSF9 compared to BSF3 fish. The apparent digestibility of DM, CP, EE and gross energy did not vary among the treatments. Conclusions These results suggest that a partially defatted BSF meal could be included up to 15% in low fishmeal-based diets for rainbow trout with no adverse effects on growth performance, fillet’s physical characteristics, gut and liver health, and diet digestibility. On the contrary, the fillet FA composition worsened while increasing the level of BSF meal in the diet.

“…SCP has found wide applications as sources of bioactive peptides, plant growth stimulants, animal feeds, food additives, cosmeceuticals, drugs, and as probiotics in aquaculture. SCP can also replace expensive soy meal and fishmeal in animal and aquaculture feeds (Sharma and Sharma, 2017;Caporgno and Mathys, 2018;Smárason et al, 2019). Cultivation of microalgae in wastewater offered the highest atmospheric carbon fixation rate (1.83 kg CO 2 /kg biomass) and rapid biomass productivity-−40-50% higher than terrestrial crops (Shahid et al, 2020).…”

The seafood industry generates large volumes of waste. These include processing discards consisting of shell, head, bones intestine, fin, skin, voluminous amounts of wastewater discharged as effluents, and low-value under-utilized fish, which are caught as by-catch of commercial fishing operations. The discards, effluents, and by-catch are rich in nutrients including proteins, amino acids, lipids containing good proportions of polyunsaturated fatty acids (PUFA), carotenoids, and minerals. The seafood waste is, therefore, responsible for loss of nutrients and serious environmental hazards. It is important that the waste is subjected to secondary processing and valorization to address the problems. Although chemical processes are available for waste treatment, most of these processes have inherent weaknesses. Biological treatments, however, are environmentally friendly, safe, and cost-effective. Biological treatments are based on bioconversion processes, which help with the recovery of valuable ingredients from by-catch, processing discards, and effluents, without losing their inherent bioactivities. Major bioconversion processes make use of microbial fermentations or actions of exogenously added enzymes on the waste components. Recent developments in algal biotechnology offer novel processes for biotransformation of nutrients as single cell proteins, which can be used as feedstock for the recovery of valuable ingredients and also biofuel. Bioconversion options in conjunction with a bio-refinery approach have potential for eco-friendly and economical management of seafood waste that can support sustainable seafood production.

“…The forage fish used in fish feeds have also reached the upper limits; therefore, it would be beneficial to provide different resources to achieve a sustainable ecosystem (Cottrell et al, 2020). In this regard, novel protein sources such as singlecell proteins including yeast, bacteria, algae and filamentous fungi (Glencross et al, 2020;Smárason et al, 2019) and aquatic weeds including Azolla sp. (Brouwer et al, 2019), Spirodela sp., Lemna 100 g/kg (R10) and 150 g/kg (R15) for 90 days.…”

The present study aimed to investigate the effects of partial replacement of fishmeal with Rapana venosa meal in diets for rainbow trout (Oncorhynchus mykiss) broodstock.The results were analysed on reproductive performance, egg fatty acid composition, serum biochemistry, antioxidant enzymes and histopathological and histomorphological changes of the experimental fish. For the trial, rainbow trout (331.04 ± 11.72 g) were fed diets incorporated with R. venosa (whelk) meal at 0 g/kg (CD), 50 g/kg (R5), How to cite this article: Sahin T, Yılmaz S, Gürkan M, Ergün S.Effects of Rapana venosa meal-supplemented diets on reproduction, histopathology and some blood parameters of rainbow trout (Oncorhynchus mykiss) broodstock.
