Description Drift gillnets landed on an average 117.8 t of sharks forming 6.9% of the total catch by drift gillnets and the peak period of abundance is during
June - August. Larodon mucmrhinrrs constituted 36.5% followed by Carcharhinus sorrah (26.1%). Scoliodon 1aticaudu.s (I 5.8%). Rhisoprionodon acutus (10.3%). Sphyrna zygaena. (1.8%), Chiloscylliom griseum, (1.6%), other Carcharhinus spp. (l~2. 7%), and other sharks (5.1%). The L =,
K and to the dominant species Carcharhinus sorrah have been estimated to be 1459 mm, 0.3993 (annual basis) and 0.0740 yr for males and
1658 mm, 0.3309 (annual basis) and -0.0901 yr for females respectively. The total mortality rate (2) is estimated to be 3.35 and 2.82 during
1991- 92 and 1992-93 respectively for males and 5.82 and 4.01 for females respectively. The natural mortality rate (M) is estimated to be 0.63
for males and 0.54 for females. The exploitation rate indicates that females are exposed to more severely to higher fishing pressure than the
males.
