Abstract

Fortysix experiments were done with the electric seine in
24 tanks with A. C. and interrupted A. C. The source of electrical
energy was a 3 KW A. C. generator of water-cooled diesel
engine. A control seining without applying electricity was conducted
for every experiment with electric ''seine,. to have a comparison for
the efficiency of electric "seine'• over control ones. Electric seine
was found to have an increased catch over control seining both in
numbers and in weight. Electric seine with two electrodes was found
to have better effect over three electrodes. Benthic fishes like Cirrhina
mrigala, Notopterus notopterus, Cyprinus carpio, Glassogobius giuris,
Ophicephalus sp. and Mystus sp. were found to be more sensitive in
electric "seine". Increased catch of small fishes like C. mriga/a,
N. notopferus and Ophicephalus sp. has been observed in electrical
"seine" in addition to larger ones.
