Against this backdrop, a trial of larval production by artificial incubation of Oreochromis niloticus eggs was carried out in the Parc de la Lékédi. A total of 60 broodstock, including 15 males and 45 females, were collected in the wild and seeded into 3 x 5 m2 breeding tanks. Individual weights ranged from 150 to 350 g, with an average of 224 g. Total lengths ranged from 20 to 26 cm. These broodstock were fed a 3 mm floating pelleted complete feed, once a day each morning. After an adaptation period of 2 weeks, egg collection from the mouths of the females began and lasted 4 months. The eggs were incubated in 1.5 l plastic bottles with a conical shape towards the beak, after being disinfected in a 30% formaldehyde solution. The physico-chemical parameters of the water were not controlled throughout the trial. As a result, egg development was possible under these conditions, but the survival rate was less than 1%.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786206238645\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9786206238645","offer_id":46896153723205,"sku":"9786206238645","price":39.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/d9e8c8c4-ba9c-4951-8a5e-da2784c6e67f.jpg?v=1747811628","url":"https:\/\/shop.autorenwelt.de\/products\/tilapia-egg-incubation-trial-at-sodepal-von-serda-zita-milendzikapi-brice-kumulungui-und-ference-matumuini","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
