ALGAL BLOOMING
• Suspend feeding and manuring schedule when the water turns deep green.
EUGLENA BLOOM
• Scum out the bloom on daily basis using floating rope made out of straw or dried banana leaves.
DAWN DISSOLVED OXYGEN DEPLETION
As soon as dawn surfacing fish is noticed, try to agitate/splash the water by manual or mechanical means. It helps in increasing dissolved oxygen level. Recirculate the same water with the help of pump or add fresh water in case of nearby water source is available.
it is also wise to partially harvest the marketable size fish
suspend manuring for few days till the dawn surfacing stops
trim branches of marginal trees
rake the bottom
DISEASE OUTBREAK
net the pond and remove clinically diseased specimens if few in number
give dip treatment in potassium permanganate solution or salt solution before releasing them back
apply lime @ ½ kg/decimal 2 times a week
contact Thana Fisheries Officer for further advice

keep few bamboo traps along the pond margin to catch snakes
walk frequently around the pond to scare snakes/birds, etc.
put poison injected eggs along the pond margin to kill otters
