In order to make decisions regarding when to harvest cultured shrimp, short-term forecasts of future growth must be compared with expected future costs and changes in the value of the shrimp harvested. As with most agricultural products, researchers and business professionals collect and maintain data on the various factors that influence growth. Though many general fixed relationships between,...

A study was carried out to evaluate polymerase chain reaction (PCR) for the detection of white spot syndrome virus (WSSV) in postlarvae and broodstock of Penaeus monodon and in potential crustacean carriers from India. Primer pairs designed for WSSV affecting Penaeus japonicus (WSSV PJ) and P. monodon (WSSV PM) were used. Both the primer pairs gave positive assay results for crustaceans showing...

This article proposes a dissolved oxygen prediction model for water quality about aquaculture to solve the problems like low accuracy and poor robustness of traditional prediction methods about water quality based on principal component analysis (PCA), fuzzy neural network(FNN), and differential evolution combined with BP algorithm (DEBP). This model can establish nonlinear dissolved oxygen pre...

Slow growth caused by viral diseases has become a major constraint in shrimp aquaculture. Laem-Singh virus (LSNV), a positive-sense single-stranded RNA (ssRNA) virus, has been identified in Penaeus monodon showing slow growth syndrome. To examine the host-range and transmission modes of the virus, 6 species of penaeid shrimp of varying life stages, sourced from the wild and from farms, as well ...

This study investigated the presence and antibiotic resistance of Salmonella spp. in a shrimp farming environment in Northeast Region of Brazil. Samples of water and sediments from two farms rearing freshwater-acclimated Litopenaeus vannamei were examined for the presence of Salmonella. Afterwards, Salmonella isolates were serotyped, the antimicrobial resistance was determined by a disk diffusi...

This study examined the current state of abandonment and conversion of shrimp ponds in several areas of Thailand and identified patterns in conversion activities. A semi-structured questionnaire was used to gather data from farmers, head villagers, and stakeholders in villages throughout Chanthaburi, Chachoengsao, and Samut Sakhon provinces. These areas were selected because they had experience...
