Resumen

The objective of this research was to evaluate the nonspecific immune response and resistance of Litopenaeus vannamei fed with nucleotide, β–glucan, and protagen diets. Shrimp juveniles with an average weight of 5.39±0.56 g were reared in glass aquaria at a density of 15 shrimps/aquarium. Shrimps were fed three times a day for four weeks at a feeding rate of 3%/bw/day. Treatment diets consisted of A: basal diet (without immunostimulant), B: β–glucan, C: protagen, and D: nucleotide, each with three replicates. At the end of feeding period, the shrimps were intramuscularly injected with Vibrio h

Resumen

Shrimp farming is one profitable sector of aquaculture and the Pacific white shrimp (Litopenaeus vannamei) is the most cultivated species worldwide. Nutrition is considered as one of the greatest challenges in shrimp farming due to its dependence on fishmeal (FM) as an ingredient in the feed. The main goal of the present work was to analyse if the substitution of FM by yellow mealworm (Tenebrio molitor) meal (TM) influences digestive enzyme expression, haemolymph parameters or the intestinal microbiota of shrimp juveniles.

The sex ratio, size frequency distribution, and diet of shrimp caught in the water column differed markedly from shrimp caught during their stay on the bottom. Pelagic migrants were mostly males (75%), extending their planktonic foray into morning hours, whereas ovigerous (12%)

Resumen

Shrimp farming is an aquaculture business for the cultivation of marine shrimps or prawns for human consumption and is now considered as a major economic and food production sector as it is an increasingly important source of protein available for human consumption. Intensification of shrimp farming had led to the development of a number of diseases, which resulted in the excessive use of antimicrobial agents, which is finally responsible for many adverse effects. Currently, probiotics are chosen as the best alternatives to these antimicrobial agents and they act as natural immune enhancers, w

Resumen

Intensive shrimp culture has encountered many problems, such as declining water quality through disease caused by pathogenic microbes, which affected mortality. This study aimed to determine any potential probiotic from Bacillus sp. collected from mangrove in East Lampung, which could be used to improve the cultured shrimps' proteolytic and probiotic activity. This is a descriptive research with sampling and data collection of bacteria from many samples of mangrove. Result shows 128 isolates Bacillus from which then it has arrived at five potential probiotic Bacillus sp. The study five Bacillu

Resumen

Abstract Active promoters are urgently needed for shrimp cells which are hard to be immortalized. Translationally controlled tumor protein (TCTP) is a widely and abundantly expressed, growth-related protein. In this study we successfully isolated the promoter (Ptctp) and ORF (= open reading frame) of the TCTP gene from Litopenaeus vannamei and analysed the promoter activity of Ptctp and the growth-promoting effects of over-expressed TCTP protein in the primary Oka organ (lymphoid tissue) cells. It was found, that cytomegavirus (CMV) promoter, highly active in mammalian and fish cells, had a dr

The extracted polysaccharide consists of galactose, glucose, and mannose. Total polyphenolic compound and total flavonoids content in CRP were determined. In vitro CRP treatment did not alter cell viability of haemocytes and significantly activated phenoloxidase (PO) activity, superoxide anion production capacity, phagocytic rate, and index in haemocytes.

Resumen

Vibriosis is one of main diseases of the black tiger shrimp Penaeus monodon infected by pathogenic bioluminous bacterium Vibrio harveyi that can cause mass mortalities in shrimp culture. The bacteria can also trigger the disease white spot syndrome virus (WSSV). An effort to produce shrimp disease-resistant strains has been done through transgenesis technology with antiviral gene transfection. By this technology, it is expected an increase in the immune response of shrimp in a variety of diseasecausing pathogens.

Resumen

Medicinal plants have been screened for their biological activity using Brine Shrimp (Artemia salina leach). Brine shrimp lethality test was used to investigate the cytotoxic activity of plant extracts. After 24 hour of treatment, the larvicidal activity was assessed on the base of percentage of larval mortality. The bioactivity of hydroalcoholic extracts of different parts of medicinal plants, at different concentrations (1-5000 µg/mL), was evaluated with the shrimp lethality assay. Lethality concentration (LC50) was obtained using probit analysis. Out of the 17 plants tested, Veratrum album

Resumen

Little is known about the learning ability of crustaceans, especially with respect to their anti-predator responses to invasive species. In many vertebrates, anti-predator behaviour is influenced by experience during ontogeny. Here, predator-naïve glass shrimp (Paratya australiensisis) were exposed to a predatory, invasive fish species, Gambusia holbrooki, to determine whether shrimp could learn to: (1) avoid the scent of Gambusia via classical conditioning; and (2) restrict their activity patterns to the night to reduce predatory encounters. Conditioned shrimp were placed in containers in aqu

Resumen

Correct management of the feeding regime in shrimp aquaculture has been beneficial. Still, when looking for improvement in shrimp performance, the results have been contradictory, and the limits between better growth and independent growth as a function of the feeding regime are not clear. In this study, trypsin and α-amylase activity, as well as an interpretation of the energy utilized for enzyme production, were evaluated in shrimp weighing 1 g. Four feeding groups were set to feed one, two, four, or eight times per day over a month, after which trypsin and α-amylase activities were evaluate

Resumen

The pathogenic bacterial infection is one of the problems in the cultivation of vannamei shrimp (Litopenaeus vannamei), causing a high mortality rate of cultured shrimp. The use of antibiotics or chemicals with inappropriate concentrations can harm the aquatic environment, cause resistance, and endanger consumer health because the residues from the chemicals used will periodically accumulate in the body of shrimp. One way to control and prevent shrimp disease is to increase the shrimp immune system by using immunostimulants from seaweed. This study aims to analyze the immunostimulant activity

The effects of cell age, reaction temperature, pH value, and salts on the inhibitory activity of shrimp chitosan (98% deacetylated) against Escherichia coli were investigated. The age of a bacterial culture affected its susceptibility to chitosan, with cells in the late exponential phase being most sensitive to chitosan. Higher temperature (25 and 37°C) and acidic pH increased the bactericidal effects of chitosan. Sodium ions (100 mM Na+) might complex with chitosan and accordingly reduce chitosan's activity against E. coli. Divalent cations at concentrations of 10 and 25 mM reduced the antiba
