White spot disease (WSD) has posed a serious threat to the China and the global shrimp aquaculture. In order to diagnose (WSSV) early and prevent the spread and outbreak of WSD, it is necessary to establish a highly sensitive WSSV diagnosis method suitable for shrimp farming sites. In this study, a pre-amplification qPCR assay from the crude extract of samples heated lysis was established, which was further compared with the universal qPCR assay to verify the shrimp samples.

Neozoa are invasive species that enter faunal communities as new species. Not infrequently, they pose a threat to local ecosystems. Climate change could further promote these developments or favor neozoa. Read More

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, .

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

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).

Goldfish is one of the preferred ornamental fish which is highly susceptible to cyprinid herpesvirus-2 (CyHV-2) infection. The present study aimed to analyse immune gene expression in a co-culture of CyHV-2-sensitized goldfish peripheral blood leukocytes (PBLs) with CyHV-2-infected fantail goldfish fin cell lines (FtGF). Goldfish were sensitized with intraperitoneal TCID dose (10/mL) of CyHV-2. Read More

In recent decades, aquaculture has played a significant role in fulfilling the vast demand for animal protein requirements and consequently in food security. However, environmental contamination and disease prevalence are considered essential challenges for the sector. In this regard, new approaches have been paved in technology to deal effectively with such challenges. Read More

Acute hepatopancreatic necrosis disease (AHPND) is an emerging shrimp () disease caused by (VP) since 2013 in Bangladesh. The aim of this work was to evaluate a PCR and RT-PCR techniques as rapid methods for detecting AHPND-positive using genetic markers. Healthy and diseased shrimp () samples were collected from three monitoring stations. Read More

A unique strain of (designated as VP) causes acute hepatopancreatic necrosis disease (AHPND), a deadly bacterial disease associated with mass mortality in cultured shrimps since 2009. AHPND is responsible for severe economic losses worldwide, causing multimillion-dollar loss annually. Because of the rapid and high mortality rates in shrimps, substantial research has been carried out to develop rapid detection techniques. Read More

Acute hepatopancreatic necrosis disease (AHPND) or formerly known as early mortality syndrome (EMS) is an emerging disease that has caused significant economic losses to the aquaculture industry. The primary causative agent of AHPND is , a Gram-negative rod-shaped bacterium that has gained plasmids encoding the fatal binary toxins Pir A/Pir B that cause rapid death of the infected shrimp. In this review, the current research studies and information about AHPND in shrimps have been presented. Read More

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.
