Special Issue Information

Dear Colleagues,

The rapid growth in modern aquaculture reflects people's increasing demands for seafood. As the global population and consumption of aquatic food increase, innovative production systems are needed. Recirculating Aquaculture Systems (RASs) have many advantages over others, such as high yield and efficiency, water conservation, environmental protection, strong system controllability, and high product quality. It can provide a suitable, stable, and controllable environment for rearing aquatic animals, and is one of the important development directions in the modern aquaculture industry.

Improvements in RASs may contribute to achieving sustainable aquaculture, and understanding RASs and applying this knowledge to the latest RAS technology is crucial. Since the 1960s, research in the above-mentioned fields has made rapid progress in many aspects; therefore, it is necessary to integrate the latest information on the development of aquaculture.

This Special Issue aims to provide the latest information on fish farming in RASs to develop the technology and basic theory of RASs. Submissions may take the form of original research, full or mini-reviews, and perspectives on topics including, but not limited to, the following:

  • Recirculating aquaculture;
  • The regulatory function of mechanical factors in RAS;
  • The interaction between the RAS and the environment;
  • Analysis of the inherent species potential for culturing in RAS;
  • New technologies for RAS;
  • Welfare of the animals reared in RAS;
  • Development of urban aquaculture using RAS.

This study investigated the growth performance and physiological and intestinal histomorphometry of juvenile tambaqui Colossoma macropomum (51.68 ± 3.87 g), fed continuously or subjected to weekly cycles of feed restriction (one day of no feeding followed by six days of feeding) associated with feeding frequencies of two or three times a day, for 84 days, in a recirculating aquaculture system (RAS). Growth performance and blood parameters were determined after 42 and 84 days. Liver, adipose tissue and intestine were collected after 84 days to determine the somatic indices, liver lipid levels and intestinal histomorphometry. Restricted fish had greater feed intake compared to continuously fed after 42 days, as well as greater specific growth rate (SGR) and better feed conversion between 43 and 84 days. No significant differences were observed for restriction, feeding frequency or the interaction for blood parameters after 42 and 84 days, somatic indices and liver lipid levels after 84 days, with the exception of plasma glucose, which was higher for restricted fish after 84 days. The feed restriction promoted a greater intestinal villi perimeter and height compared to continuously fed fish, as did fish fed twice a day compared to those fed three times a day, with an interaction between factors. We concluded that six days of feeding per week and twice-daily feeding frequency can be used as a feeding protocol for tambaqui juveniles over an 84-day period in RAS and this management protocol can also help reduce feed and labor costs in the production of this species.

Abstract
Photoperiod serves as a significant environmental signal for organisms and plays a critical role in regulating their metabolic processes. This research aimed to investigate the lipid metabolism and nutritional quality of adults Litopenaeus vannamei (wet weight: 11.27 ± 0.73 g, body length: 12.45 [...] Read more.
Photoperiod serves as a significant environmental signal for organisms and plays a critical role in regulating their metabolic processes. This research aimed to investigate the lipid metabolism and nutritional quality of adults Litopenaeus vannamei (wet weight: 11.27 ± 0.73 g, body length: 12.45 ± 0.42 cm) under five photoperiods (0L:24D, 8L:16D, 12L:12D, 16L:8D, and 24L:0D) for 40 days in recirculating water systems (RASs). The 24L:0D group increased lipid metabolism, as indicated by increased lipid metabolism enzyme levels and related gene expression linked to lipogenesis. Additionally, shrimp in the 24L:0D exhibited the highest value of crude fat. The 0L:24D showed a significantly reduced content of crude fat compared with the 8L:16D and 12L:12D. In 24L:0D, the content of total essential amino acids (TEAAs), total hydrolyzed essential amino acids (THEAAs), and total non-essential amino acids (TNEAAs) increased significantly. Similarly, the content of polyunsaturated fatty acids (PUFAs) in 24L:0D was also higher than in other groups. Conversely, 0L:24D resulted in lower metabolic activity and a reduction in PUFA content. In conclusion, prolonging light could benefit shrimp cultivation. This study thoroughly examined the effects of varying photoperiods on muscle quality and lipid metabolism in L. vannamei, providing essential insights for the improvement of indoor aquaculture environments. Provision of light for 24 h improves production but has some adverse effects on animal welfare, so a 16 h light cycle is recommended. Full article
