BELLY DEPTH STUDIES FOR SHRIMP TRAWLS-PART III

Abstract

Earlier investigations with 13.69 m ( 45') four seam shrimp
trawl indicated the optimum depth of belly to be 70 meshes.
Present communication details further experiments on similar lines
with a bigger shrimp trawl of size 17.07 m (56') without overhang.
The resu]ts obtained have not only given corroborating
evidence in support of the earlier findings but also helped in
arriving at a relationship that for a given stretched width of belly
'L' the stretched depth of beUy could be either 2L/5 or 40% of
•L' with an allowance of ± 2 meshes.
