These minerals can be either macro or micro minerals that are supplied to the fish body through diets or absorbed from their surrounding environment via skins, gills or alimentary tract. However, the bioavailability of these minerals to the fish body is influenced by several factors, including the intake level of the nutrient, interactions with other minerals or nutrients and cultured fish species. To enhance effective bioavailability to the farmed fish, sustainable, healthy and well-mineral-balanced diets must be adopted to achieve better fish growth performance, and a high survival rate for high production and productivity while ensuring the resilience of the cultured environment. In this review, the quantitative mineral composition of different mineral sources was reviewed and reported. In addition, mineral requirements in several cultured fish both freshwater and marine water fish species for five macro minerals (calcium, phosphorus, sodium, potassium and magnesium) and seven micro minerals (zinc, iron, copper, manganese, iodine, chromium and selenium) were compiled and reported. Nile tilapia is dominating freshwater cultured species in Tanzania, followed by catfish and rainbow trout, while milkfish is dominating cultured marine species practiced along the coastline from the Northern Tanga region to the Southern Mtwara region. Moreover, this review also covers information on the relationship between minerals and farmed fish, the mechanism of mineral absorption in fish and implications associated with bioavailability of minerals in both aquatic animal body and their surrounding environment, as well as mineral research in future perspectives in the aquaculture industry development. Therefore, the review comprises all this information on the importance of minerals and their bioavailability in farmed fish for sustainable aquaculture production and productivity.</p>","PeriodicalId":100114,"journal":{"name":"Aquaculture, Fish and Fisheries","volume":"5 3","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aff2.70067","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, recirculating aquaculture systems are heavily dependent on beneficial bacterial communities for waste product removal and water quality maintenance, with opportunistic pathogens constituting an inherent component of these microbial communities.

Hop acids are important components of SBY, which differentiate it from other yeast derivatives and often limit their application due to bitter taste. The present study examined the relationship between SBY and its associated hop acid when incorporated into an aquafeed. The effect of SBY on the growth, lysozyme activity, colour and nutritional composition of Nile tilapia (<i>Oreochromis niloticus</i>) over a 10-week nutritional trial was assessed. Four treatment feeds were formulated: a control feed (CTRL) with no SBY or hop acids, a feed with 300 mg hop acids/kg (HA), a 12% SBY-supplemented feed (SBY) and a 12% SBY-supplemented feed with 300 mg hop acids/kg (SBY+HA). One hundred and forty-four fish were distributed into 12 tanks, with each tank randomly assigned one of the treatment diets. Key metrics such as weight gain, specific growth rate, feed conversion ratio, viscerosomatic index, hepatosomatic index, conditioning factor and fillet yield were assessed. Additionally, deboned fillets were evaluated for lightness, a and b(LAB) colour and proximate composition. The SBY-supplemented feed without hop acids (SBY) resulted in lower growth, compared to the control (CTRL). However, the HA feed showed improved growth, compared to the control. Small differences were noted in fillet colour, but no significant differences were found in proximate composition across treatments. This study suggests that SBY, enriched with hop acids, could be a valuable protein supplement in aquafeed, providing production benefits without affecting final fillet quality.</p>","PeriodicalId":100114,"journal":{"name":"Aquaculture, Fish and Fisheries","volume":"5 2","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aff2.70065","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143852721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optimisation of feeding in next-generation precision fish farming requires developing models for decision support and process control. Black box ML and AI models are often very efficient but have drawbacks, such as requiring large amount of training data and reduced performance in novel situations where no data are available. Thus, developing realistic process models of fish appetite, feeding decisions, feed intake, energetics and growth is necessary. Such models are essential for predicting fish performance, for example, feed intake, waste from uneaten feed and faeces, growth, in novel ‘what if’ scenario testing. We have built a conceptual model based on a review of major neurophysiological mechanisms and feedback loops controlling appetite and food intake in fish. Building on this, we have developed the FishMet model: a new extensible stochastic simulation framework that represents the basic feedback loops controlling appetite, feeding decisions, energy budget and growth in salmonid fish. The appetite and feeding decision model in FishMet is the novel advance, while the bioenergetic part follows the established theory. The model is supported by server-based components and open API for data assimilation and on-demand model execution that allows to use FishMet as a digital twin. We demonstrate relatively good prediction of stomach and gut digesta transit and food intake in the rainbow trout <i>Oncorhynchus mykiss</i>. The digital twin also demonstrated good prediction of growth and feeding efficiency in a pilot scale experiment on the Atlantic salmon <i>Salmo salar</i>.
