| सारांश: | A study on population dynamics and feeding biology of mudskipper,
periophthalmus chrysospilos was conducted in bayan bay coastal water, penang from
july 2013 to july 2014. This study comprised of three components: (i) length-weight
relationships (lwr) and fulton condition factor (k); (ii) growth, mortality, and
recruitment pattern, and (iii) stomach content analyses. The main objectives of this
study are: (i) to investigate the length-weight relationships of p. Chrysospilos in
different sexes and months, (ii) to elucidate the fulton condition factor and its relation
to the monthly variations and water physio-chemical parameters, (iii) to study the
growth parameters, mortality and recruitment pattern of p. Chrysospilos and finally
(iv) to determine the feeding activities and feeding guild of p. Chrysospilos according
to different sex, months and water tide. Results show the exponential values (zj) of the
lwr for all individuals (n = 714), male and female fish, and fish caught during dry
and rainy months were greater than 3, indicating of positive allometric growth. The
fulton’s condition factor (k) for all individuals, male, female, and fish caught in dry
and rainy months were 0.998 ± 0.121, 0.9907 ± 0.106, 1.008 ±0.138, 1.018 ± 0.115
and 0.998 ± 0.123, respectively. The b and k values for male and female fish were not
significantly different. The b value in dry months is significantly higher than in rainy
months.
