Statement: A mass mortality of shrimps in ponds on entire Andhra coast has recently been reported due to the presence of a virus.

Courses of Action:

1. The water of the ponds affected should immediately be treated for identifying the nature of the virus.

2. The catching of shrimps from the ponds should temporarily be stopped.

3. The fishermen should be asked to watch for the onset of such phenomenon in nature.

  • A.Only I follows
  • B.Only I and II follow
  • C.All follow
  • D.Only II and III follow
  • E.None of these

Answer: A

Correct answer: Only I follows

Identifying the virus is the necessary first step, since nothing sensible can be decided until it is known what is killing the shrimps and whether it is transmissible. II does not address the problem - the shrimps are dying in the ponds, and stopping the catch neither halts the deaths nor answers any question, though it might be justified later on food safety grounds once the virus is known. III is too vague to be a course of action; watching for a phenomenon nobody can yet describe achieves nothing.
