Human disturbances, such as overfishing, may disrupt predator-prey interactions and modify food webs. Underwater surveys were carried out at six shallow-water reef barrens in temperate waters of northern-central Chile from October to December 2010 to describe the effects of predation, habitat complexity (low, medium and high) and refuge availability on the abundance and population structure of ...

Reducing small shrimps in the Gulf of Maine pink shrimp fishery with a new size-sorting grid system Pingguo He, Institute for the Study of Earth, Oceans and Space and NH Sea Grant University of New Hampshire, Durham, NH. (603) 862-3154, [email protected] Vincent Balzano, F/V “North Star”, Saco, Maine, USA INTRODUCTION Since the implementation of the Nordmore Grid in the Gulf of Maine pink shri...

There is an increasing need to predict the effects of global climate change on ecologically important marine organisms and a demand for proactive solutions to reduce CO2 emissions. CO2 sequestration is one such method. While this offers a practical solution, recognition should be given to the potential for considerable localised effects on marine organisms in the event of leakage. This laborato...

A systematic investigation was conducted in Lake Taihu in autumn of 2013 and 2014, in order to understand the environmental fate of microcystins (MCs) and evaluate the health risk from MCs. Samples of water, algal cells, macrophytes, shrimps and fish were taken to detect MCs by HPLC-MS/MS after solid phase extraction. Widespread MC contamination in water, algal cells, macrophytes, shrimps and f...

Lactic acid alone and its combined application with nisin were evaluated for reducing population of naturally occurring microorganisms on chilled shrimp. Fresh shrimps were dipped in 0, 1.0% and 2.0% (v/v) lactic acid alone and their combined application with 0.04 (g/L/kg) nisin solution for 10 min. Total plate counts of aerobic bacteria (TPCs), Psychrotrophic counts, population of Pseudomonas ...

The pink shrimp Farfantepenaeus duorarum may acquire pollutants, helminths and symbionts from their environment. Statistical associations were studied between the symbionts and helminths of F. duorarum and pollutants in sediments, water and shrimps in Campeche Sound, Mexico. The study area spatially overlapped between offshore oil platforms and natural shrimp mating grounds. Spatial autocorrela...

A procedure is proposed by which recruit numbers and parental biomass of shrimps stocks can be derived, given a series of catch-per-effort data and estimates of a few ancillary variables. In the Gulf of Thailand, shrimp recruitment decreased with decreasing egg production, but increased with decreasing total (mainly fish) standing stock. The net result of these counteracting effects was an over...

This study was carried out for the molecular level identification of recombinant protein vaccine efficacy, by oral feeding against white spot syndrome virus infection, with the comparison of viral mRNA transcriptional levels in shrimp cells. For the determination of WSSV dilution ratio for the vaccination experiment by oral feeding, in vivo virus titration was carried out using different virus ...

This article presents the nutritional value of shrimp on the strength of its nutrient composition and daily value (DV%). With its relatively lower lipid content (~ 1%), the DV (%) of 100 g shrimp for an adult human is 75%, 70% and 35% for eicosapentanoic acid + docosahexanoic acid, essential amino acids (methionine, tryptophan and lysine) and protein respectively. The lower atherogenic (0.36) a...

the survival, growth, reproductive and life span characteristics of phallocryptus spinosa were studied at different temperatures in the laboratory. three replicates of 200 newly hatched nauplii were transferred to culture containers at 15, 20, 25 and 30˚c. the larvae were fed with unicellular algae dunaliella tertiolecta and chemically treated yeast known as lansy pz. survival and growth rate o...
