A relationship between antimicrobial peptide gene expression and capacity of a selected shrimp line to survive a Vibrio infection ArchiMer
De Lorgeril, Julien; Gueguen, Yannick; Goarant, Cyrille; Goyard, Emmanuel; Mugnier, Chantal; Fievet, Julie; Piquemal, D; Bachere, Evelyne.
Understanding of antimicrobial defence mechanisms of penaeid shrimp should help in the design of efficient strategies for the management and disease control in aquaculture. In this study, we have specifically analysed the expression in circulating hemocytes of antimicrobial peptides (AMPs) encoding genes, such as PEN2 and PEN3, ALF, crustin, lysozyme and a putative cysteine-rich peptide. We evidenced a relationship between the level of expression of some AMPs and the successful response of the shrimp, Litopenaeus stylirostris, to circumvent a pathogenic Vibrio penaeicida infection. Additionally, significant differences in some AMP transcript amounts are evidenced between control, non-selected shrimp line and the third generation breeding of shrimp selected...

Aménagement des pêcheries côtières de Nord-Bretagne, algues-crustacés ArchiMer
Arzel, Pierre.
Today, the seaweed industry's main products are the alginates and carraghenanes. The industrial network faces many problems. However, it remains prosperous since it ranks fifth in the world for alginate production and third for caraghenanes'. This stability which seems safe on a middle term standpoint must not conceal the crisis which previously hit Fucus' exploitation. Rightly so, being harvested until approximately 1950 for soil amendment purposes, coastal kelp (i.e. Fucus), was replaced by chemical fertilizers. Brittany's production which was reaching 180 000 cubic metre in the twenties, close to 200 000 tons of fresh kelp, would have become non existent if it had not been converted into seaweed meal for livestock feed. The market demand was then...

Description of ten additional ossicles in the foregut of the freshwater crabs Sylviocarcinus pictus and Valdivia serrata (Decapoda: Trichodactylidae). Repositório Alice
LIMA-GOMES, R. C.; LIMA, J. de F.; MAGALHÃES, C..
The morphology of stomach ossicles of decapod crustaceans provides valuable information on their phylogeny and biology. We herein described ten new ossicles in the foreguts of two trichodactylid crabs, Sylviocarcinus pictus (H. Milne-Edwards, 1853) and Valdivia serrata White, 1847, in addition to previously described 38 ossicles, which are also recognized and listed. Five specimens each of S. pictus and V. serrata were selected for morphological analysis of gastric ossicles. The stomachs were obtained after removing the carapace, and they were fixed in 10% formalin for 24 hours. After this procedure, the stomachs were immersed in a solution of 10% Potassium Hydroxide (KOH) and heated to 100 °C during 60 minutes for tissue maceration. At this point, the...

Litopenaeus vannamei stylicins are constitutively produced by hemocytes and intestinal cells and are differentially modulated upon infections ArchiMer
Farias, Natanael Dantas; Falchetti, Marcelo; Matos, Gabriel Machado; Schmitt, Paulina; Barreto, Cairé; Argenta, Nicolas; Rolland, Jean-luc; Bachère, Evelyne; Perazzolo, Luciane Maria; Rosa, Rafael Diego.
Stylicins are anionic antimicrobial host defense peptides (AAMPs) composed of a proline-rich N-terminal region and a C-terminal portion containing 13 conserved cysteine residues. Here, we have increased our knowledge about these unexplored crustacean AAMPs by the characterization of novel stylicin members in the most cultivated penaeid shrimp, Litopenaeus vannamei. We showed that the L. vannamei stylicin family is composed of two members (Lvan-Stylicin1 and Lvan-Stylicin2) encoded by different loci which vary in gene copy number. Unlike the other three gene-encoded antimicrobial peptide families from penaeid shrimp, the expression of Lvan-Stylicins is not restricted to hemocytes. Indeed, they are also produced by the columnar epithelial cells lining the...

Manuel des protocoles de campagne halieutique. Campagnes de surveillance de la pêche côtière des crustacés du site de Flamanville CRUSTAFLAM ArchiMer
Schlaich, Ivan; Miossec, Dominique.
Fishery and ecological studies have been carried out by Ifremer as part of the environnement monitoring of the nuclear power plant of Flamanville ( programme supported by "Electricité de France"). Their aim is to follow the natural fluctuations of the major species in the previous years and evaluate the impact of the power plant on the local fishery from the moment it has begun to operate. This paper presents the data collected between 1977 and 2002 and the creation of a naturel reserve which induced a modification of the relative index calculation and the introduction of a precise lobster numbering in the reserve. These points are described here with the sampling methodology and the tagging technique used. The associated data base specification is given...

Massive Gene Expansion and Sequence Diversification Is Associated with Diverse Tissue Distribution, Regulation and Antimicrobial Properties of Anti-Lipopolysaccharide Factors in Shrimp ArchiMer
Matos, Gabriel Machado; Schmitt, Paulina; Barreto, Caire; Farias, Natanael Dantas; Toledo-silva, Guilherme; Guzman, Fanny; Destoumieux-garzon, Delphine; Perazzolo, Luciane Maria; Rosa, Rafael Diego.
Anti-lipopolysaccharide factors (ALFs) are antimicrobial peptides with a central β-hairpin structure able to bind to microbial components. Mining sequence databases for ALFs allowed us to show the remarkable diversity of ALF sequences in shrimp. We found at least seven members of the ALF family (Groups A to G), including two novel Groups (F and G), all of which are encoded by different loci with conserved gene organization. Phylogenetic analyses revealed that gene expansion and subsequent diversification of the ALF family occurred in crustaceans before shrimp speciation occurred. The transcriptional profile of ALFs was compared in terms of tissue distribution, response to two pathogens and during shrimp development in Litopenaeus vannamei, the most...

Metal and metalloid bioaccumulation in the Pacific blue shrimp Litopenaeus stylirostris (Stimpson) from New Caledonia: Laboratory and field studies ArchiMer
Metian, Marc; Hedouin, Laetitia; Eltayeb, Mohamed M.; Lacoue-labarthe, Thomas; Teyssie, Jean-louis; Mugnier, Chantal; Bustamante, Paco; Warnau, Michel.
The present work aimed at better understanding metal and metalloid bioaccumulation in the edible Pacific blue shrimp Litopenaeus stylirostris, using both laboratory and field approaches. In the laboratory, the bioaccumulation kinetics of Ag, Cd, Co, Cr, and Zn have been investigated in shrimp exposed via seawater and food, using the corresponding gamma-emitting radiotracers (Ag-110m, Cd-109, Co-57, Cr-51, and Zn-65) and highly sensitive nuclear detection techniques. Results showed that hepatopancreas and intestine concentrated the metals to the highest extent among the blue shrimp organs and tissues. Moulting was found to play a non negligible detoxification role for Co, Cr and, to a lesser extent, Zn. Metal retention by L stylirostris widely varied (from...

New hosts and distribution records of Braga patagonica, a parasite cymothoidae of fishes from the Amazon. Repositório Alice
TAVARES-DIAS, M; ARAÚJO, C. S. O.; BARROS, M. S.; VIANA, G. M..
Specimens of Braga patagonica Schiödte & Meinert, 1884 (Isopoda: Cymothoidae) from freshwater fishes deposited in Ichthyological Collection of Amazon National Research Institute (INPA), in central Amazon and from fishes from eastern Amazon (Brazil) were investigated. Prevalence, infection intensity and body measures of B. patagonica for different populations of this cymothoid in wild fishes species from Amazon were carried out. Four species of Serrasalmidae, one Characidae, one Cichlidae, one Cynodontidae, one Curimatidae, one Acestrorhynchidae and one Sciaenidae were recorded as new hosts for B. patagonica in the Amazon. This study indicates a low intensity and low parasitic specificity of B. patagonica, and also recorded the first parasitism by this...

Osmoregulation pattern and salinity tolerance of the white shrimp Litopenaeus vannamei (Boone, 1931) during post-embryonic development ArchiMer
Chong-robles, Jennyfers; Charmantier, Guy; Boulo, Viviane; Lizarraga-valdez, Joel; Enriquez-paredes, Luis M.; Giffard-mena, Ivone.
The euryhaline white shrimp Litopenaeus vannamei lives in both coastal and oceanic areas through ontogeny. Its osmoregulation pattern and variations in its tolerance to salinity are partially known from several studies under different experimental conditions (developmental stages, salinities and acclimation procedures). Although L. vannamei is recognized as one of the most euryhaline penaeid species, with adults and juveniles exhibiting an hyper-hypo-osmoregulatory pattern and being able to tolerate a wide salinity range, little is known on larval and early postlarval strategies to cope with salinity fluctuations. In order to establish their euryhalinity range and to fully understand the ontogenetic changes in L. vannamei osmoregulatory pattern, we...

Unilateral eyestalk ablation improves molting frequency and reproduction in Macrobrachium amazonicum females. Repositório Alice
BASTOS, A. M.; LIMA, J. de F.; TAVARES-DIAS, M..
This study has investigated the influence of unilateral eyestalk ablation on the survival, molting frequency, fecundity, reproductive output, and fertility of M. amazonicum females. We divided 96 females into with ablation and without ablation groups with six replicates. Water quality, growth, survival rate, intermolt period, molts number, and ovigerous females over a 90-day period were monitored. Unilateral eyestalk ablation reduced intermolt period by 30% and increased molts number, ovigerous females, and reproductive output. Our findings indicate that unilateral eyestalk ablation positively influences reproduction in M. amazonicum and is appropriate for females of this species having a body length of greater than or equal to 70 mm.

Volcanism and arthropods: a review Ecología austral
Elizalde,Luciana.
Volcanic eruptions are natural disturbances that impose multiple changes in ecosystems. Arthropods are among the most diverse organisms on the planet and play key functional roles in all ecosystems. Existing information on the effects of volcanic disturbances on arthropods is scattered. The aim of this review is to fnd generalities in the responses of arthropods from terrestrial and aquatic environments to volcanism. Mainly (1) what effects do volcanic disturbances have on arthropods?, (2) what characteristics make certain species more or less susceptible to volcanic disturbances?, and (3) how do arthropod communities reassemble after a volcanic disturbance? Terrestrial and aquatic arthropods show similar responses to volcanic disturbances. Volcanism can...
