Women play a major role in the accession to food security because of their significant contribution to agriculture. However, very few data exists on women's contribution to the Cote d'Ivoire fish production. The objective of this study was to evaluate the ability of fish farms owned by women to contribute to the fish production in Cote d'Ivoire. A survey has been conducted on women fish farms characteristics and their production capacity. Only 5.98% of 301 farms belonged to women with a contribution to the total production of 2.89%. They are mostly farmers (44.44%) aged 30 to 60 years (88.89%), native of the regions (66.67%) where they had their farms. Tilapia and catfish are the main species produced with a semi-intensive (83.33%) farming system in pond. The area of production is less than 1 hectare (77.78%). Commercial or farms-made feeds are preferably used as fish feeds. Women-owned farms production is characterized by the tilapia commercial weigh over 300 g (66.67%) and a yield of 1000 kg/ha/year (77.78%). By their choice of production system, feeds and their production capacity, women can contribute to set up a sustainable production environment of farm fish in Cote d'Ivoire.

Un Aquathon a été organisé les 20 et 21 novembre 2019 à Abidjan (Côte d’Ivoire) sur le thème des déchets plastiques dans l’océan. Trente participants de 18 structures publiques et privées ont expérimenté les outils et méthodes collaboratifs de l’innovation ouverte pour proposer des solutions. Il en ressort que les déchets plastiques doivent être éliminés et peuvent être transformés et valorisés pour assainir l’environnement et protéger la vie et la biodiversité. Quatre prototypes de solutions ont été collégialement identifiés : i) un processus de réduction des rejets plastiques dans l’environnement, ii) la valorisation des déchets plastiques à partir de moyens locaux, iii) la création d’emplois par le tri des déchets plastiques, et iv) un outil de suivi de la qualité biogéochimique des eaux. Ces solutions devront être approfondies avec les industriels, les consommateurs et les laboratoires d’innovation pour aboutir à leur mise en œuvre.

Artemia salina, the main first-feeding protein source of the catfish Clarias gariepinus larvae is relatively scarce and very expensive in Côte d'Ivoire and it raises the cost of catfish fingerlings production. To reduce the feed cost, feeding trial was completed with five isonitrogenous (35%) diets formulated by substituting artemia protein in control diet by soya protein at 25% (SB25), 50% (SB50), 75% (SB75) and 100% (SB100) level. Clarias gariepinus larvae initial body weight 0.0064 ± 0.001 g were stocked at 1 larvae L -1 and fed with the experimental diets three times daily ad libitum for 49 days. At the end of the growth trial, diets SB25 and SB50 present similar growth with the control diet. The low growth recorded from fish fed SB75 and SB100 highly affected final biomass despite the best survival rate recorded. Best values of feed conversion ratio were recorded from larvae fed control diet followed by SB25, SB50. High levels of soya proteins in diets affect feed palatability and larvae growth, vigour, motility and reactivity. Compounded feeds SB25 and SB50 can be used us low cost Clarias gariepinus larvae diets without adverse effects on growth and survival compared of artemia control diet.
