“…ALP activity is also affected by temperature; we found that with the increase of temperature, the ALP activity of crucian carp under different treatments first increased and then decreased. The change was relatively significant at 24 and 27 • C, with increases of 56.55% and 38.09%, respectively, compared to that at 17 • C, and ALP is known to have the highest activity at 24 • C and promoted the metabolism, bone formation, and fat synthesis of crucian carp [45]. At the same time, it also enhances the destructive resistance of crucian carp skin [46].…”

Fish is one of the important sources of energy and protein, and proper water temperature is key to successful fish breeding. The authors of this study evaluated crucian carp growth, mucus antibacterial properties, and immune indicators at 17, 21, 24, 27, and 31 °C. The results indicated that in the range of 17–31 °C, the resistance of epidermal mucus to Vibrio harveyi decreased with temperature rising. At 24 and 27 °C, the activities of lysozyme and catalase significantly increased; alkaline phosphatase activity, superoxide dismutase activity, and total protein concentration first increased and then decreased with rising temperature; the highest values were observed at 24 °C, with increases of 56.55%, 26.64%, and 44.52%, respectively, compared to those under the 17 °C treatment. When the treatment reached 27 °C, the temperature had an effect on the growth and antibacterial properties of crucian carp, and the activities of alkaline phosphatase and superoxide dismutase were significantly reduced. At temperatures of 17–24 °C, the survival rate of crucian carp could reach more than 93%, and at the temperature of 24 °C, the specific growth rate reached the highest value of 43.29%. Therefore, the most favorable temperature for the long-term breeding of crucian carp was found to be 24 °C. This study provides a favorable experimental basis for the establishment of intelligent aquaculture systems and the setting of water environment parameters.

“…However, there is increased evidence of the positive impact of dietary supplementation with SSF products. For example, dietary supplementation with a commercial SSF product (Synergen TM , Altech) increased lupin diet digestibility in rainbow trout [80] and DDGS-based diet in turbot [31]. Moreover, supplementing a plant feedstuff-based diet with an extract produced by SSF of brewer's spent grain increased the digestibility of dry matter, starch, cellulose, glucans, and energy in European seabass [37].…”

Aquaculture requires new, economical, and eco-friendly protein sources to replace traditional fisheries and plant ingredients. Using agriculture by-products as protein sources would reduce land-based feed production pressure and waste production, promoting a circular economy and sustainable aquaculture. Distiller’s dried grains with solubles (DDGS) is the main by-product of bioethanol production. Corn DDGS has a high protein level, but its high fiber content limits its use as a feed ingredient, particularly for carnivorous fish. Solid-state fermentation (SSF) uses lignocellulosic-rich substrates, such as DDGS, for microbial growth in the near absence of water, promoting enzyme production that degrades the lignocellulosic matrix, increasing free reducing sugars, protein, and antioxidant levels of the substrate. In the present work, the SSF of corn DDGS with Aspergillus carbonarius, A. ibericus, and A. uvarum was tested. Then, the digestibility of the most promising fermented DDGS (in terms of upgraded nutritional composition) was tested by including it in a reference diet (70% of a reference diet; 48% crude protein; 15% crude lipids) for European seabass (Dicentrarchus labrax) juveniles (171 g averaged weight; trial duration of 52 days). Among the fungi tested, Aspergillus ibericus led a generally higher upgrading of the DDGS nutritional composition, leading to a high amount of protein (from 42.7 to 49.7 g N/kg DM), phenolic compounds (1.49 to 4.86 mg/g caffeic acid equivalents), free sugars (9.5 to 31.9 mg/g), and enzyme production (45 U/g and 68 U/g of cellulase and xylanase, respectively), and a high reduction in acid detergent fiber and neutral detergent fiber content (up to 29 and 43%, respectively). Compared to the unfermented DDGS, fermented DDGS presented increased protein, lipids, starch, and energy digestibility, while phosphorous digestibility was similar. Compared to the reference diet, dietary inclusion of unfermented or fermented DDGS increased trypsin and chymotrypsin activities. The activity of digestive enzymes was not affected by the inclusion of fermented DDGS, except for amylase activity, which was lower with the fermented DDGS than with the unfermented DDGS diet. In conclusion, SSF of DDGS enhanced its nutritional value, increasing DDGS digestibility when included in diets for European seabass juveniles.

“…Sustainable and eco-friendly fish farming necessitates the finding of alternative protein and oil feed ingredients to fishmeal and oil that are highly digestible in farmed species (Morales et al 2018). Fish meal use in commercial salmonid diets has plummeted from almost 65% to as low as 15% over the last three decades thanks to the extensive scientific research conducted in Atlantic salmon (Salmo salar) and rainbow trout (Onchorhynchus mykiss) (Davies et al 2021). The biggest fishmeal replacer in commercial salmonid diets has been the full fat or defatted soybean meal and its by-products and, to a lesser, extent rape and sunflower seed meals and wheat and corn gluten meals have been utilized (Gatlin et al 2007;Kumar et al 2020;Davies et al 2021).…”

Aquaculture is the fastest growing animal production sector globally. However, its sustainability heavily relies on the development of nutritionally balanced cost-effective and environmentally friendly aqua feeds for fish and crustacean species that are already being farmed or the candidate species for intensive farming in the future around the world. Therefore, feeds produced for farmed aquatic species should be highly digestible in terms of nitrogen and phosphorous contents in order to avoid excessive release of these nutrients into the water column through solid and soluble discharge. Excessive nitrogen and phosphorous in the water are the main reason of eutrophication occurring causing severe depletion of oxygen and creating hypoxia for many aquatic organisms living inside water column. Strategies like formulating aqua feeds on required DP/DE (Digestible Protein/Digestible non-protein Energy) basis for farmed species and using synthetic enzymes as feed additives in order to make plant phosphorous bioavailable for fish are being utilized by the commercial aqua feed producers around the world. Fermenting plant protein ingredients with microorganisms and using prebiotics and probiotics as feed additives are also considered a viable option to reduce the nutrient load of aquafarms since these have been shown to increase the digestibility of feed ingredients via increased gut health maintaining the optimal composition and environmental conditions for gut microbiome. In this regard, this review is intended to emphasize the importance of the sustainability efforts of aquaculture production from the perspectives of environmentally friendly aqua feed formulations and improvements based on the recent knowledge gathered for the effects of dietary external enzyme supplementation and fermentation of plant ingredients on growth and wellbeing of rainbow trout (Oncorhynchus mykiss) throughout the world.
