The invention discloses an Odontobutis obscura factory culture method using a bottom framework and a laying net to realize the bottom isolation technology, thus isolating the Odontobutis obscura living quarter from night soils, effectively ensuring culture water quality, and reducing diseases; the Odontobutis obscura is small in activity scope, enjoys cave inhabitation, and preys in an assault mode; the method uses a baffle to replace the water plant function, thus ensuring the Odontobutis obscura quantity per unit area, so the Odontobutis obscura can more conveniently rest, move and prey; in addition, the bait source is strictly controlled in a culture process, and fresh baits are regularly fed in the whole process, thus ensuring the bait fish quantity per unit area, and preventing Odontobutis obscura from killing each other under food shortage. The Odontobutis obscura factory culture method is a whole new production mode under the best artificially created conditions; compared with a conventional method, the Odontobutis obscura factory culture method is small in land occupation, high in unit yield, short in culture period, thus reducing culture cost, and improving production efficiency.
