Sibling cannibalism in dorada under experimental conditions. I. Ontogeny, dynamics, bioenergetics of cannibalism and prey size selectivity

Cannibalism among embryos and larvae of Brycon moorei (Characidae) occurs during daytime and night-time, and persists under permanent darkness. Embryos and larvae of dorada provisioned with formulated feed over the first week of exogenous feeding did not survive, except for those exerting cannibalism. When oered alternative fish prey [embryos of Prochilodus magdalenae (0·5–0·8 mg) and Oreochromis niloticus (9·10 mg)], 1-day-old embryos of dorada preferred preying on these, thereby reducing early cannibalism. However, this promoted depensatory growth and more intense cannibalism later in the larval stage. Dorada provisioned with Artemia nauplii in excess showed more homogeneous growth and higher survival, most cannibalistic acts being restricted to the first 24 h of exogenous feeding, just after oral teeth were fully developed (21 h after hatching). Provisioning dorada with Artemia nauplii a few hours before their oral teeth were fully developed reduced early cannibalism from 41 to 15%. High proportions of deformed fish caused higher mortality, both directly and indirectly, as they promoted early cannibalism, depensatory growth and more intense cannibalism among larvae. The initial sorting of embryos, based on their occupation of the water column improved survival significantly during the first week of exogenous feeding, up to 52% in progenies containing -1, in the first and second weeks, respectively. These results indicate that cannibalism in dorada can be mitigated eciently through appropriate rearing procedures, and open promising perspectives for the intensive culture of this fast-growing tropical species

Les artisans semenciers, les haricots et leurs agents pathogènes

En se saisissant du cas d'une association d'artisans semenciers, les Croqueurs de carottes, cet article a pour objectif d’éclairer l'articulation entre gestion de la biodiversité cultivée et gouvernance de la santé des plantes par ces acteurs. Face à un règlement phytosanitaire européen interdisant la commercialisation de semences de haricot porteuses d’un « organisme de quarantaine », les artisans semenciers défendent leurs pratiques qui consistent à « vivre avec » les maladies en les considérant comme partie intégrante de leur système de production. Par leurs efforts pour faire reconnaître leurs modes d’attachement aux maladies des plantes, ils ne font pas seulement valoir leurs pratiques de gestion, mais construisent et défendent aussi leur identité professionnelle.By exploring the case of an association of artisanal seed producers, Les Croqueurs de Carottes, this paper sheds light on how these stakeholders interconnect management of crop biodiversity and governance of plant health. Faced with European phytosanitary regulations that prohibit the sale of bean seeds carrying “quarantine pests”, these artisanal seed producers defend their practices, which consist of “living with” diseases by regarding them as an integral part of the production process. Through their efforts to gain recognition for their methods and acceptance of plant diseases, they are not only promoting their management practices, but are also building and asserting their professional identity
