| The french Guyana sh rimp fishery has grown from the sixties, following the development of US a nd Japanese fleets. The EEZ delimitation in 1977 and the french policy towards promotion of french vessels allowed, since 1980, the emergence of french ship-owners. The paper analyses the recent economie evolution of the enterprises and underlines first the importance of this activity within regional economy, and second its dependance on imported inputs. The french policy leads to an incrcase of the share of the net added value that remains in the depanment, but it also come to a poor financial status of the french ship-owners. The data collected and given in this paper will be used to feed a bio-economic model o f the shrimp fishery. |

| This study describes a polymerase chain reaction using restriction fragment length polymorphism (PCR-RFLP) assay based on the 16S rRNA mitochondrial gene to identify commercial food products of wide range of Penaeidae and Pandalidae shrimp species commercialised in the Tunisian market. Phylogenetic analyses on 16S rRNA mitochondrial gene were used to study the relationships among the considered species. Penaeidae shrimp species was easily differentiated and confirmed by direct sequencing, showing a genetic distance of 0.34 with respect to Pandalidae species. A rapid and reliable PCR method using restriction fragment length polymorphism (RFLP) with three restriction enzymes (HpyCH4III/ MboI / AluI) was optimized for unambiguous differentiation of shrimp... |

| For several years the fishermen of the West Indies have directed their activities towards new fishing grounds, notably the bathyales zones adjacent to island plateaux up to approximately 1000 metres in depth. Explorations earned out since 1989 have shown that diverse crustacean populations could be exploited. However, populations and exploitable stocks arc not well known. The use of crustaceans traps as a fishing technique permits the capture of shellfish, shrimps and prawns of which at least six species could have commercial interest. The main objective of this work is do draw up an inventory of the principal commercial species as well as the accompanying species belonging to the subordres Decapoda macrura, anomura, brachyura, and to the orders Isopoda... |

| in this study we evaluated the effects of the probiotic Pediococcus acidilactici MA18/5M on shrimp, Litopenaeus stylirostris (also called Penaeus stylirostris), first on antioxidant defences and secondly on the oxidative stress status in the shrimps' haemolymph and digestive gland. We conducted two experiments with the same protocol in which shrimps were fed two diets for three weeks: a control diet and a probiotic diet containing 1 g of live P. acidilactici MA18/5M kg(-1). In the first experiment, the shrimps were found to be healthy over the trial period; no mortalities and non-detectable signs of infection were recorded. These resulted in high final survival rates (above 90% in both treatments). On the other hand, during the second trial, carried out at... |

| The availability of Indian specimens of Plesionika persica (Kemp, 1925) and P. reflexa Chace, 1985 provided more information on the taxonomy around these two species. Moreover, it is the first record of P. persica to India. Although P. taiwanica Chan and Yu, 2000 is superficially rather similar to P. persica, there are many differences between them and probably it is inappropriate to establish a species group for these two species. It is likely that all previous records of P. ensis (A. Milne-Edwards, 1881) from India actually represent P. reflexa Chace, 1985. Nevertheless, the present Indian specimens of P. reflexa have more than 10% COI sequence divergence from the topotypic materials of both P. ensis and P. reflexa, and the epipods at the pereiopods III... |

| This study compares the antioxidant and antimicrobial transcriptional expression of blue shrimps reared according to two different systems, BioFloc Technology (BFT) and Clear sea Water (CW) and their differential responses when facing an experimental sublethal hydrogen peroxide stress. After 30 days of rearing, juvenile shrimps were exposed to H2O2 stress at a concentration of 30 ppm during 6 hours. The oxidative stress caused by H2O2 was examined in the digestive glands of the shrimp, in which antioxidant enzyme (AOE) and antimicrobial peptide (AMP) gene expression were analysed by quantitative real-time PCR. Results showed that rearing conditions did not affect the expression of genes encoding AOEs or AMPs. However, H2O2 stress induced a differential... |

| Fourteen species of shrimps belonging to four genera of the family Atyidae are reported from the Fiji Islands. Three genera are represented by only one species each: Antecaridina lauensis (Edmondson, 1935), Atyoida pilipes (Newport, 1847) and Atyopsis spinipes (Newport, 1847) while the fourth, Caridina is represented by eleven species (including one new, Caridina devaneyi spec. nov. which is described and illustrated). Keys are provided to separate the genera and species. Two species, Caridina japonica De Man, 1892 and C. longirostris H. Milne Edwards, 1837 are recorded from Fiji for the first time. C. devaneyi spec, nov., C. fijiana Choy, 1983 and C. nudirostris Choy, 1984 are so far known only from Fiji and may be endemic to the island of Viti Levu. All... |
