Claims: I claim:

1. A method of grading caged fish as to size, comprising the steps of providing first and second fish cages, at least said first cage containing large and small fish, each cage having walls which are free of any openings large enough to allow the escape of either the large or the small fish therein, moving said cages together while in the water, placing a barrier with graded openings between said cages, said openings being too small for the largest fish in said cages to pass through but small enough for the smallest fish in said cages to pass through, providing temporary access openings in the cage walls large enough and positioned so as to permit all of the fish in said cages to reach said barrier, and urging the fish in one of said cages towards said barrier and towards the other cage.

2. A method as in claim 1 including closing said access openings, removing said barrier, and separating said cages from one another when the fish have sufficiently separated into two groups, the large fish in one cage, and the small fish in the other cage.

3. A method as in claim 1 for harvesting said fish, said method comprising removing the larger fish from said one cage after being separated from the smaller fish in the cage.
