Le secteur de la p\u00eache et de la vie aquatique repr\u00e9sente un pilier essentiel de la base d’approvisionnement du pays. Le poisson est l’un des principaux produits alimentaires arabes qui atteignent des niveaux \u00e9lev\u00e9s d’autosuffisance. Les ressources halieutiques rec\u00e8lent un potentiel \u00e9norme, car une grande partie d’entre elles n’est pas encore exploit\u00e9e. exploit\u00e9. Selon le chef du d\u00e9partement d’aquaculture de la Direction de la P\u00eache Marine et des Ressources Halieutiques, des exp\u00e9riences scientifiques ont prouv\u00e9 que la pratique de l’activit\u00e9 aquacole dans les \u00e9tangs d’irrigation conduit \u00e0 une fertilisation naturelle de l’eau, ce qui contribue \u00e0 l’abandon des engrais chimiques, ainsi qu’\u00e0 l’\u00e9levage. le rendement de production, en plus de la production de poissons qui peuvent \u00eatre \u00ab commercialis\u00e9s localement \u00bb comme les esp\u00e8ces de mulet, de carpe et de tilapia du Nil.<\/p>\n

Tous les organismes vivants ont besoin d’\u00e9nergie et de nourriture, qu’ils obtiennent de plusieurs sources diff\u00e9rentes. Cela est \u00e9vident dans les cha\u00eenes alimentaires, qui font r\u00e9f\u00e9rence aux diverses sources de nourriture dont les organismes vivants ont besoin pour survivre au sein de leurs \u00e9cosyst\u00e8mes. Les cha\u00eenes alimentaires commencent par les plantes qui fabriquent leur leur propre nourriture, c’est pourquoi ils sont appel\u00e9s producteurs, suivis des consommateurs, qui sont des organismes qui ne peuvent pas fabriquer leur propre nourriture.<\/p>\n

Il convient de noter que les cha\u00eenes alimentaires incluent la pr\u00e9sence de deux types fondamentaux d’organismes autotrophes : ou ce que l’on appelle des produits, qui sont :<\/p>\n
