A review on the recent advances and application of vaccines against fish pathogens in aquaculture.

Aquac Int 2022 May 2:1-30. Epub 2022 May 2.

Centre for Nanobiotechnology, Vellore Institute of Technology (VIT), Vellore, Tamil Nadu India.

Globally, aquaculture has faced serious economic problems due to bacterial, viral, and various other infectious diseases of different origins. Even though such diseases are being detected and simultaneously treated with several therapeutic and prophylactic methods, the broad-spectrum activity of vaccines plays a vital role as a preventive measure in aquaculture. However, treatments like use of antibiotics and probiotics seem to be less effective when new mutant strains develop and disease causing pathogens become resistant to commonly used antibiotics.

Cyprinid herpesvirus 2 (CyHV-2) is the etiological agent of herpesviral hematopoietic necrosis disease (HVHND), which causes severe mortality in ornamental goldfish (), crucian carp (), and gibel/prussian carp (). Quick and hassle-free point-of-care detection of CyHV-2 is vital for the maintenance of ornamental fish health. In this manuscript, we describe the development of a rapid and sensitive RPA (recombinase polymerase amplification) assay, coupled with lateral flow dipsticks (LFD), that can achieve sensitive diagnosis of CyHV-2 in goldfish within 20 min at 36 °C with the satisfactory detection limit of 10 gene copies per reaction.

Lectin protein families are diverse and multi-functional in crustaceans. The carbohydrate-binding domains (CRDs) of lectins recognize the molecular patterns associated with pathogens and orchestrate important roles in crustacean defense. In this study, two lectin homologs, a single CRD containing C-type lectin (CTL) and an L-type lectin (LTL) domain containing endoplasmic reticulum Golgi intermediate compartment 53 kDa protein (ERGIC-53) were identified from the freshwater prawn, .

Intelligent fish farm-the future of aquaculture.

Aquac Int 2021 13;29(6):2681-2711. Epub 2021 Sep 13.

National Innovation Center for Digital Fishery, China Agricultural University, Beijing, China.

With the continuous expansion of aquaculture scale and density, contemporary aquaculture methods have been forced to overproduce resulting in the accelerated imbalance rate of water environment, the frequent occurrence of fish diseases, and the decline of aquatic product quality. Moreover, due to the fact that the average age profile of agricultural workers in many parts of the world are on the higher side, fishery production will face the dilemma of shortage of labor, and aquaculture methods are in urgent need of change. Modern information technology has gradually penetrated into various fields of agriculture, and the concept of intelligent fish farm has also begun to take shape. Read More

Fishery Machinery and Instrument Research Institute of Chinese Academy of Fishery Sciences, Shanghai, 200092 The People's Republic of China.

Seafood has important health benefits, and the growing demand for aquatic products has stimulated rapid trade development. Using 2000-2018 data from the UN Comtrade Database, this study first introduced the export scale, product structure, and market distribution of China's aquatic products. Then, using an extended constant market share model, we investigated the factors affecting fluctuations in China's aquatic product exports to the USA, Japan, South Korea, the Association of Southeast Asian Nations (ASEAN), and the European Union (EU).

A recent study related to aquaponics has shown that hydroponic lettuce grown in aquaculture-derived supplemented water grew significantly better than lettuce grown in a conventional hydroponic system. The principal objective of this study was to verify this finding in a larger setup. Even though the aquaculture water that was added to the aquaculture-based hydroponic system contained relatively high amounts of sodium, we were still able to observe an enhanced growth performance of the lettuce in that system compared to the lettuce grown in the conventional hydroponic nutrient solution.
