this fish
Dear Randy
Thank you for writing in – although im not an expert !! that’s what I thought -
Chrysichthys nigrodigitalis - what the French
and ivorians were doing well at breaking the hatchery cycle and grow out in Cote D
Ivoire in 1990s – 120 MT in one year late 90s from one farm unfortunately this stopped
during the later troubles – If it is this fish they are found widely in the commercial
tilapia cage nets on Lake Volta entering when smaller with the tilapia and then
growing to significant sizes 1.5 – 2.0kg in just 6-8months from the feed dropping down
through the cage – They are highly valued in Ghana (3 X kg price compared to Clarias
and tilapia) whilst still not grown commercially to any scale – to my knowledge? -
But surely have potential as a commercial species – look out for French published papers
on the Machiron as they call it from 1990s …… Perhaps my French and francophone
colleagues can write in and tell us more details?
Best wishes will
Cher Randy
- Bien que je ne sois pas un expert !! C’est ce que je pensais - Chrysichthys
nigrodigitalis - ce que les Français et les Ivoiriens
faisaient bien pour briser le cycle des écloseries et se développer en Côte D Ivoire dans
les années 1990 - 120 MT en une année à la fin des années 90 d’une ferme,
malheureusement, cela s’est arrêté au cours des derniers troubles - Si c’est ce poisson
qu’ils trouvent en abondance dans les filets commerciaux de cages à tilapia du lac Volta
qui entrent plus petits avec le tilapia et atteignent ensuite des tailles significatives
de 1,5 à 2,0 kg en seulement 6 à 8 mois, à la suite de la chute des aliments à
travers la valeur au Ghana (3 X kg prix comparé à Clarias et tilapia) sans grandir
commercialement à une échelle - à ma connaissance? - Mais il y a sûrement du potentiel en
tant qu'espèce commerciale - recherchez les articles publiés en français sur le
Machiron,
comme ils l'appellent depuis les années 1990…
Peut-être que mes collègues français et francophones pourraient nous écrire et nous donner
plus de details?
Amicalement Will

This one is a chrysichthys species. Where was it caught?
