Aquaculture is one of the most resource-efficient and sustainable ways to produce animal protein. The Food and Agriculture Organization predicts that cultivated aquatic species will provide around 53% of the world's seafood supply by 2030. Further growth of intensive farmed aquatic species may be limited by a shortage of feed resources. The aquaculture sector therefore needs to intensify its search

The flavour of aquatic animal products is distinct from terrestrial foods, facilitating a competitive marketing advantage. However, the flavour of aquatic animals can also be highly variable. Importantly, differences are reported in the flavour of animals from aquaculture and wild-capture systems. These differences can erode consumer acceptance of aquaculture products and reduce financial returns to

Decapod iridescent virus 1 (DIV1) is an emerging viral pathogen that seriously threatens crustacean farming and has caused enormous economic losses in recent years. This virus was originally isolated and identified from diseased crayfish Cherax quadricarinatus and shrimp Litopenaeus vannamei in Fujian and Zhejiang, China, in 2014 by two research groups. In 2019, the Executive Committee of the International

Edwardsiella ictaluri, a non-zoonotic Gram-negative bacterium, has been known to science for more than 4 decades. It was reported for the first time in 1979 in Ictalurus punctatus in the USA and later in Pangasianodon hypophthalmus and Pelteobagrus fulvidraco in Asia. Even though catfish species are more susceptible to E. ictaluri, other fish species are also affected, and up to 44 fish species in

The global increase in seafood demand has resulted in significant growth in aquaculture production in a wide range of aquatic species. Consequently, this has led to an industry-wide need to find sustainable feed ingredients that would meet the nutritional requirements used in aquafeeds. The associated dependency on plant by-products as the major alternatives has brought concerns to aquaculture through

A wide range of fish species, as well as crustacean species, have been cultured in either fresh and/or marine water, and these cultured species may differ in different countries or different regions in the world. But these cultured species are consistently subjected to the threat of common, or their own specific, diseases caused by various pathogens during the process of aquaculture, including parasites

In the aquatic environment, fish are subject to different pollutants and environmental variations that favour stress on animals, making them vulnerable to pathogens. Fish parasites are excellent biological indicators of environmental quality, as their parasitic population may increase or decrease in response to changes in water parameters and/or the presence of pollutants. Ectoparasites are considered

Chinese mitten crab (Eriocheir sinensis) culture in rice paddy fields is a representative model of integrated agriculture-aquaculture systems developed in China over the last 30 years. The economic and ecological benefits of rice-crab coculture are significantly improved compared to those of rice monoculture. Under coculture conditions, rice provides shelter for crabs and improves the aquatic environment

The present work employed a systematic review and meta-analysis to quantify the overall effects of various types of insect meal on special growth rate (SGR), feed conversion ratio (FCR) and protein efficiency ratio (PER) of aquatic animals. A total of 107 studies published from 1990 to 2021, targeting 23 freshwater and 17 marine fish species, employing 17 insect species as a replacement for fishmeal

Feed restriction in fish and crustaceans is gaining interest due to its unusual acceleration of growth after a feed deprivation period. This phenomenon, known as compensatory growth, allows deprived organisms to reach the weight of never-stressed counterpart organisms. Since feed is the major economic and ecological burden of fish and crustaceans farming, succeeding to reduce its quantity without loss

Seaweeds are macroscopic forms of phylogenetically diverse assemblage of marine algae that grow in oceans, thriving among profoundly harsh environmental conditions. They are cultivated in many maritime nations primarily for edible applications; besides hydrocolloid extraction is the second largest domain of utility for this renewable biomass. The farming practices have been traditionally evolved in

The abundance of nitrogen compounds, phosphorous compounds and organic matter in biofloc technology (BFT) aquaculture systems creates an ideal medium for increasing microbial communities and load. The abundance of microbial DNA found in BFT aquaculture systems is hypothesised to be among the greatest in current aquaculture systems. Several factors mediate the bacterial diversity, relative abundance

Pen shells hold some potential for cultivation, but information on aquaculture activities is fragmentary, and no sustained or commercial production of any such species is currently in place. We reviewed information available worldwide on reproductive cycles, wild juvenile collection, spat production in hatcheries and cultivation systems for 45 pen shell species. We found information on the topics of

Giant freshwater prawn (GFP), Macrobrachium rosenbergii, is a tropical species widely cultured in several countries across the world. It has high market demand accompanied by attractive prices. The global farmed production of this species in 2018 was 237,124 tonnes (t) valued over 1.93 billion USD.

The species is distributed in many countries in South Asia to South-East Asia. The current production of the species is largely contributed from the capture fisheries as there are several inherent problems associated with its farming. The major

The emergence and prevalence of bacterial pathogens in freshwater aquaculture systems is a growing concern as the economic losses associated with diseases are mounting and impacting the fishery sector. One way of controlling fish mortality and morbidity is using bacteriocin-secreting probiotics, which are generally considered safe without any adverse effects that usually accompany other treatment strategies

One of the bottlenecks for commercial implementation of integrated multi-trophic aquaculture (IMTA) is the difficulty in quantifying its environmental performance. We reviewed a large body of literature to determine the variability in nutrient dynamics within different IMTA systems (open sea-cages, land-based flow-through and recirculating aquaculture systems), with the aim to provide a generic framework

With the rapid development of aquaculture and the gradual decrease in fishery resources, aquatic animal welfare (AAW) has received increasing attention from animal protection organisations, government departments, biologists, fish culturists and consumers. Although environmental enrichment (EE) can potentially benefit AAW, the relevant results are sharply mixed, and the drivers for these discrepancies

For more than three decades, infectious diseases have been one of the major causes of economic losses in the global shrimp industry. One of the deadliest of the shrimp pathogens is white spot syndrome virus (WSSV), which causes mass mortality in farmed shrimp. Various aspects of WSSV pathogenicity have been studied, but in this review, we will focus only on one of them, namely metabolic reprogramming

To maximise productivity, a better understanding of the underlying causes of subfertility that lead to inferior offspring and high mortality is imperative. In decapod crustaceans, most research has focused on female reproductive performance, with little attention given to male fertility. Paternal genetic contribution is critical to both successful embryonic and post-embryonic development. Assessment
