Harmful Effects on Toxin Dinoflagellates in Shrimp Culture Ponds

If vannamei pond affected In vibriosis (antenna cut)50% , and the pond water colour is red brown,how to control vibriosis &how to change water colour? immediately

02.03.2015 Dear Mr. Prakash Chandra Behera Kindly throw some more light on the followings; What are the most commonest toxin producing dinoflagellates found in shrimp ponds (Peneus monodon & P.vennamei) in India? Do you often experience toxin producing dinoflagellate blooms? What are the luminescence dinoflagellates in shrimp ponds? We here in Sri Lanka, some times experience luminescence dinoflagellates with dips in production performances but not toxin producing dianoflagellatrtes. More than the mechanical injuries by the the cell wall processes of the diatom Chaetocerus which are brown algae, usually bloom in shrimp ponds at higher salinities, it is the organic matter that begins to decay after an algal crash that causes problems.

Namaste sir. How much ferrous sulfate apply in pond.

Sir, What is the best method to control dark green colour water during culture period. About 80-90doc

In my pond prawns are converted colour to red and 2 or 3 days after they becomes dead what can i do water depth is 3½ feet and mud is ½ feet pond is 5 acrs and prawns are max 3 to 4 lks i experts

In one of my pond water color is full of blackish brown ? Even pH fluctuation in a day in almost 0.8-1. I had applied zeolite products,liming but too it's not changing . And weekly 40cm water exchange is going on and with that within week 10-15hours flow through . Daily around 12hrs sludge removing . But too water color is not changing . Why? What can I do for this ? Any solutions ?

Is there any possibility of frequent dinoflagellate blooms causing low survival rates and retarded growth in the shrimp ponds?. Can the toxic effect the of dinoflagellates can cause disproper functioning of hepatpancreas in shrimp juveniles or adults. Do diniflagettates have any role in the slow growth syndrome nowadays commonly seen during the culture of P. Monodon .
