species of gerreids for the first time from the Jaffna lagoon, Sri Lanka.
Gerreids are economically important fish found along the coastal regions
of Sri Lanka. Seven species namely Gerres abbreviatus, Gerres
acinaces, Gerres filamentosus, Gerres lucidus, Gerres
oblongus, Gerres oyena and Pentaprion longimanus have
been recorded in Sri Lankan waters. However, only two species of gerreids,
Gerres abbreviatus and Gerres oblongus have been recorded
from the Jaffna lagoon, so far. During the present investigation samples
were collected from Pasaiyoor, Kurunagar, Kakkaiteevu and Ponnalai coastal
areas from commercial catches by siragu valai, hand nets, hook and line
and bottom trawling. The morphometric characters were observed, measured
and examined and three new species of gerreids were recorded. Those are
Gerres filamentosus, Gerresacinaces and Gerres
lucidus. The distinctive features to identify those species and a
key for identification discussed in detail in the present study. The record
of these species is an important contribution to ichthyofauna of Northern
Sri Lanka. The occurrence of these species in the Jaffna lagoon can be
explained that they may have migrated due to the environmental changes
from the Indian ocean.]]>Anonymous, 19951995Anonymous,20002000Fukuhara, T., A. Chakraborty and Y.
