Number of poorly fed individuals was high in both the species. These species breed throughout the year. The male : female ratio of H. bleekeri
for 1989-’05 and of A. imbricatus for 1997-‘05 were 1:0.98 and 1:1.36 respectively. The length-weight relationship was: Log W= -8.7298 +2.7297 Log L for H. bleekeri and Log W = - 6.4691 +2.3119 Log L for A. imbricatus.
