The proportion associated with this problem is 

76%2Fx = 13%2F52,

where x is the unknown number of fish in the lake.


Solve it for x:  x = %2876%2A52%29%2F13 = 304.


It is your answer.


It is well known problem on proportions.


See the lesson
    - Using proportions to estimate the number of fish in a lake
in this site.

The language, wording and the way on how the problem is formulated in this post makes me scared.

These dates Jan.1 and Feb.1 are absolutely irrelevant.

It is not for the first time I see this formulation in the forum, so badly formulated.


Unfortunately . . .
