Infectious diseases reported in warm‐water marine fish cage culture in East and Southeast Asia—A systematic review

Abstract

According to the latest report of the Food and Agriculture Organization of the United Nations (FAO), global aquatic animal production grew on average 5.3% per year between 2001 and 2018. As of 2018, production was at 82.1 million tonnes (valued at USD 250.1 billion), and of this tonnage, around 9% (with a value of USD 35.4 billion) was reported to be from marine finfish production, which is predominantly in Asia, and mostly in East and Southeast Asia (De Silva & Phillips, 2007; FAO, 2020a).The most common form of marine fish farming in Asia is cage culture, and the most commonly farmed species include amberjack (Seriola spp.), cobia (Rachycentron canadum), pompano (Trachinotus ovatus) and different types of groupers (Epinephelus spp.) and snappers (Lutjanus spp.) (De Silva & Phillips, 2007). This type of aquaculture has been growing in Asia over the last decade due to an increasing demand for live fish in the restaurant trade in the People's Republic of China (PR China

Applying genetic technologies to combat infectious diseases in aquaculture

“…Aquaculture, currently the fastest growing food production industry, plays a key role in producing and supplying fish, shellfish and algae. However, the mass culture of animals in any environment carries with it a high risk of contracting, propagating and spreading infectious disease 2,3 . Some diseases affecting fish and shellfish can lead to 100% mortality or necessitate complete destocking.…”

Disease prevention and treatment are necessary, but current options are often costly, ineffective and can negatively impact animal welfare, local ecosystems and product quality.…”

Editorial: Beneficial effects of functional ingredients in feed on immunity improvement and growth promotion of aquaculture animals

“…Consequently, the poor feed palatability, decreased food intake, reduced health and growth performance of farmed animal induced by receiving low-fishmeal diets have recently gained increasing attention (Lazzarotto et al, 2018;Niu et al, 2019;Wattanakul et al, 2019). On the other hand, Due to the rapid expansion of farming scale, the increased rearing densities and deteriorated aquatic environment leads to an outbreak in disease frequency (Li et al, 2020;Jahangiri et al, 2022). Given the use of antibiotics is being restricted, it is particularly important to develop safe and effective ingredients to improve both the growth and health of aquaculture animals.…”

Given the use of antibiotics is being restricted, it is particularly important to develop safe and effective ingredients to improve both the growth and health of aquaculture animals.Here, we inspire a Research Topic including 10 papers on dietary ingredients influencing the growth performance, meat quality, ovarian development, intestinal histology, antioxidant activity and immunity of economic aquatic animals, aiming to highlight the strategies and fundamental mechanisms for promoting the sustainable development of aquaculture based on both the experiments and theory.To alleviate growth reduction and enteritis caused by low fish meal diets, Yao et al evaluate the different inclusion level of Schizochytrium limacinum in diets, and demonstrated that 0.6% S. Limacinum supplementation can improve the growth performance, promote hepatopancreas lipid metabolism, reduce apoptosis, promoteFrontiers in Marine Science frontiersin.org 01…”

The Effect of Short-Term Artificial Feed Domestication on the Expression of Oxidative-Stress-Related Genes and Antioxidant Capacity in the Liver and Gill Tissues of Mandarin Fish (Siniperca chuatsi)

“…With the development of large-scale and intensive aquaculture, excessive aquaculture density and poor water quality and environment have led to an increase in stress factors in the environment, resulting in oxidative stress in farmed animals [13]. Oxidative stress is a common bodily response mechanism that occurs after being affected by harmful factors and is related to the occurrence of many diseases [14].…”
