Indigenous peoples of North America, Australia, and New Zealand have a long tradition of harvesting freshwater animals. Over generations of reliance and subsistence harvesting, Indigenous peoples have acquired a profound understanding of these freshwater animals and ecosystems that have become embedded within their cultural identity. We have identified trans-Pacific parallels in the cultural significance of several freshwater animal groups, such as eels, other finfish, bivalves, and crayfish, to Indigenous peoples and their understanding and respect for the freshwater ecosystems on which their community survival depends. In recognizing such cultural connections, we found that non-Indigenous peoples can appreciate the deep significance of freshwater animals...

Molecular approach indicates consumption of jellyfish by commercially important fish species in a coastal Mediterranean lagoon

Until recently, jellyfish have been ignored as an important source of food, due to their low nutritional value. Here, quantitative PCR was used to detect and quantify the DNA of the jellyfish Aurelia coerulea in the gut contents of commercially important fish species from the Thau Lagoon. Individuals from five fish species were collected during two different periods: the bloom period, when the pelagic stages of A. coerulea are abundant, and the post-bloom period, when only the benthic stage – polyps – is present in the lagoon. The DNA of A. coerulea was detected in the guts of 41.9% of the fish analysed, belonging to four different species. The eel Anguilla anguilla and the seabream Sparus aurata were important jellyfish consumers during the bloom and...

Effets létaux et sublétaux à long terme d'un nonylphénol polyéthoxyle, le NP 5 sur la civelle
Provedor de dados: 5
Autores: Bocquene, Gilles; Miossec, Laurence.
Studying different concentrations, we have determined LT 50 of a non-ionic surfactant on elver eel: the polyoxyethylated nonylphenol NP 5. Then we studied sorne sublethal effects on fish behaviour and histological effects on gills, during 21 days. We demonstrated primary effects on gills structure and we believe in an impairing of the central nervous system.

Utilisation de données concentrées au niveau des criées pour l'évaluation de la production des navires de pêche artisanale côtière
Provedor de dados: 5
Autores: Gondeaux, Evelyne; Durand, Jean-louis; Flores, Domingo.
L'évaluation des quantités débarquées en pêche artisanale a toujours constitué un problème important. L'élaboration d'une base de données fiable améliorerait grandement l'appréhension de ce secteur économique en grande partie informel.  Ce document est une contribution à la mise au point d'une méthode d'estimation des débarquements des navires de petite pêche. L'utilisation de données concentrées au niveau des criées à été privilégiée. Ce choix s'explique par deux raisons. D'une part il est ainsi possible de valoriser une quantité non négligeable des données archivées, et de faire un bilan de l'acquis. D'autre part, la méthode proposée permet de limiter l'utilisation de stratégies d'échantillonnage coûteuses aux fractions de la flottille qui n'utilisent...

Les prises accessoires de la pêcherie de civelles (Anguilla anguilla) dans l'estuaire de la Loire en 1987
Provedor de dados: 5
Autores: Guerault, Daniel; Desaunay, Yves; Bellois, Pierre; Grellier, Patrick; Robin, Jean-paul; Robineau, Brigitte.
A survey of the glass-eel fishery in the Loire estuary in 1987 (265 boats, 117 tons gasseel, 13733 fishing trips) showed that 16 fishery species constitute the by-catch (49,3 million individuals, mainly juveniles, among which 98 % consist in flounder, sprat and brown shrimp). The analysis of catches in space and time leads to proposaIs for Iimiting the impact during the last fishing weeks. Taking into account the naturai mortality rates of the concerned juveniles, an attempt is made to estimate the actuai impact of the glasseel fishery, after a delay. Only 10 % of the caught brown shrimps wouid have been recruited in the summer shrimp fishery. Up to 85,5 to 97,6 % of juvenile fishes would have disappeared during the following year by natural mortality.
