| description |
Distribution and abundance, reproductive biology, growth pattern and their
relationship to physicochemical parameters have been studied on long snouted catfish,
Plicofollis argyropleuron, locally known as Goh. This study was conducted in Merbok
estuary, Kedah. The fish samples were analysed from the catches of artisanal fishermen
collected from Jan-10 to Jan-11. Fish are most abundant and frequently occurred in Feb-10
and their relationship with physicochemical parameters were observed. Generally, rainfall
tends to be the main factor that influences their abundance and occurrence. Monthly
samples from 30 to 50 of Plicofollis argyropleuron were collected with the size varied
from 162 mm to 336 mm. The maturity stages of male and female were classified into five
different stages namely immature, maturing, mature, ripe and spent according to physical
appearances of the gonad and histological method. Their spawning season is Jan-10 and
Apr-10 ( in males) and Mar-10 and Aug-10 (in females) which suggested that this species
exhibit asynchronous reproductive behavior. Relative condition factor value, K for all
months is more than 1 indicates the level of fish health, environmental conditions and
nutrient supply are at the optimum level for this species reproduction in Merbok estuary.
The growth pattern of this species is concurrent with the tropical fish growth pattern. |
