Shrimp farmers have reported mass mortality of white shrimp (Litopenaeus vannamei), reaching 2-3 kg/day in Gerongan Village, Kraton District, Pasuruan Regency mid-2021. Preliminary analysis suggests that was caused by bacterial diseases. Thus, to find out the main pathogen causing mortality, present study investigated microbial composition rearing media vannamei) infected feces disease (WFD) an...

The development of shrimp aquaculture in Mexican coasts of the Gulf of Mexico began to be explored using the Pacific white shrimp Litopenaeus vannamei in the mid 90's. Many concerns over the risk of disease transmission to the economically important native penaeids, have been the main deterrent for the aquaculture of L. vannamei in the region. Concurrently, more than 10 years of research experi...

Vannamei shrimp (Litopenaeus vannamei) is a type of that often cultivated. This study aims to identify ectoparasites and their prevalence in vannamei the village Pantai Gading, Kec. Secanggang Kab. Langkat. research method survey method, where observed ponds are 3 ponds, samples taken as much 5% stocking density biota. Samples were randomly then examined at Laboratory Faculty Agriculture, Unive...

Mating behavior has been described for very few species of penaeoid shrimps. We describe some of the environmental conditions under which mating of Litopenaeus vannamei took place in the ocean, as inferred by the presence of attached spermatophores on the thelycum of females, combined with the presence of mature males with empty ampulla terminalis, both evidence of recent copulation. Out of a t...

Vannamei shrimp (Litopenaeus vannamei) production continues to decline due parasitic attacks on ponds in North Gorontalo Regency. Ectoparasites are one of the factors that can cause failure cultivation vannamei shrimp. This study aims determine type ectoparasites, intensity, and prevalence cultured traditional The sampling research was carried out at five stations. this taken random 5 plots tot...

Vibrio parahaemolyticus is a causative agent of human serious seafood-borne gastroenteritis disease and even death. Shrimps, often eaten raw or undercooked, are an important reservoir of the bacterium. In this study, we isolated and characterized a total of 400 V. parahaemolyticus strains from commonly consumed fresh shrimps (Litopenaeus vannamei, Macrobrachium rosenbergii, Penaeus monodon, and...

Hemocyanin (HMC) has been shown to participate in multiple roles of immune defence. In this study, we investigated the antiproliferative effect and underpinning mechanism of HMC from Litopenaeus vannamei in vitro. Sulforhodamine B (SRB) assay indicated that HMC could dramatically inhibit the growth of HeLa cells, but not 293T cells under the same conditions. Moreover, typical morphological feat...
