Length-weight relationships, condition factor and growth parameters of Periophthalmus chrysospilos (Bleeker, 1852) (Gobiiformes: Gobiidae) in Bayan Bay, Penang, Malaysia

This study reports the length-weight relationships (LWR), body condition factor (Kn) and growth parameters of Periophthalmus chrysospilos in Bayan Bay of Penang, Malaysia. The values of exponent b for all categories of fish were higher than 3 indicating a positive allometric growth. The mean conditi...
