Steps urged to prevent fish mortality in rainy season
In the rainy season every year when the weather remains overcast and the sun rarely shines, dissolved oxygen in fish farms decreases to a lethal level which may cause mass scale fish mortality leading to huge financial losses due to collapse of the fish crop. Director General, Fisheries Punjab Dr Muhammad Ayub told APP here on Sunday that in such circumstances, fish farmers are advised to reduce manuring and feeding to half, especially during the peak rainy season, and to maintain water level up to five feet at least, according to a press release.
