Mantis shrimps (Crustacea: Stomatopoda) are potential aquaculture species as they are constantly fished from the wild to satisfy demands of the seafood industry. Breeding capacity of mantis shrimps in captivity is scarce and implies a gap in this area to achieve successful aquaculture practices for this species. A preliminary observation was conducted with locally obtained mantis shrimps Miyake...

Suppression subtractive hybridization of Penaeus monodon hemocytes challenged with white spot syndrome virus (WSSV) has identified the viral responsive gene, PmVRP15, as the highest up-regulated gene ever reported in shrimps. Expression analysis by quantitative real time RT-PCR revealed 9410-fold up-regulated level at 48 h post WSSV injection. Tissue distribution analysis showed that PmVRP15 tr...

The effect of the number of spawnings on several biochemical components of ovary, hepatopancreas, and haemolymph was investigated. Shrimps of two origins were compared; wild-caught and pond-reared spawners. Individually tagged females were sampled at the end of a production period in a commercial hatchery. Females with multiple spawnings had a higher Ž . gonadosomatic index GSI , increased leve...

We rated some reproductive characteristics of white shrimp Litopenaeus vannamei (Boone, 1931) males using 46 farmed individuals (weighing 21.42±0.56 g) and 40 wild individuals (weighing 36.10±0.72 g). In farmed shrimps, spermatophore mean weight was 8.94±0.51 mg; total mean sperm count was 3.90±0.27 x 106 in each spermatophore; and mean percentage of normal sperm was 86.9±0.37 %. In wild indivi...

Rimicaris exoculata dominates the megafauna of several Mid-Atlantic Ridge hydrothermal sites. Its gut is full of sulphides and iron-oxide particles and harbours microbial communities. Although a trophic symbiosis has been suggested, their role remains unclear. In vivo starvation experiments in pressurized vessels were performed on shrimps from Rainbow and Trans-Atlantic Geotraverse sites in ord...

Symbiotic relationships between shrimps and other invertebrates are a very common phenomenon in tropical environments. Although the caridean shrimp-ascidian association has been known for many years, the nature of this relationship is still unclear. The current study investigated the association between the caridean shrimp Odontonia sibogae (Bruce, 1972) and solitary ascidians. A combination of...

Background: Sea foods contain high level of unsaturated fatty acids. The aim of this study is comparison of ώ3 and ώ6 levels in wild and farmed green tiger shrimp (P.semisulcatus). Materials and Methods: in this study 120 shrimps (wild=60 and farmed=60) selected. Analysis of Fatty acids was performed by Gas Chromatography. Two-factor variance difference analysis used for demonstration the effec...

Several rare or uncommon, mostly infaunal decapod crustaceans are reported from intertidal and shallow subtidal habitats of Lombok, Indonesia. The alpheid shrimps Alpheus angustilineatus Nomura & Anker, 2005, Athanas shawnsmithi Anker, 2011, Jengalpheops rufus Anker & Dworschak, 2007, Salmoneus alpheophilus Anker & Marin, 2006, Salmoneus colinorum De Grave, 2004, and the laomediid mud-shrimp Na...

Tritium accumulations in each organism as organic bound form are expressed as the R value which is defined as the ratio of tritium specific activity in lyophilized organisms (ƒÊCi/gH) to that in water (ƒÊCi/gH). The maximum R values were 0.5 in diatoms, Chaetoceros gracilis, 0.5 in brine shrimps, Artamia salina, and 0.32 in Japanese killifish, Oryzias latipes under the growing condition where t...
