The Population Dynamics of the Mudskipper, Periophthalmus barbarus (LINNEAUS 1766) (TELEOSTEI, GOBIIDAE) and the Implication for Conservation and Management in the Mangrove Swamp of Iko River Estuary, Southeastern Nigeria | Chapter 05 | Recent Advances in Biological Research Vol. 3
The population dynamics of Periophthalmus barbarus in the mangrove swamp of Iko River estuary, southeast of Nigeria were obtained from a twenty four month length composition data ranging 4.6 – 14.5 cm total length (TL) (mean 9.1841± 1.6346: n = 2,876) corresponding to 1.16 – 50.6 g total weight (TW) (mean = 9.9626 ± 5.4796) the growth was exponential. The asymptotic length (L∞) of the Powell-Wetheral plot (L∞ = 15.03 cm) was seeded into FSAT II (FAO-ICLARM Stock Assessment Tools II) software to obtain best estimates of von Bertalanfy growth parameters as L∞ = 16.22 cm TL, growth coefficient (K) = 1.2 year-1, age of fish at zero length, to = 0.071, longevity, tmax = 2.5 years. The estimated growth performance index, φ' = 2.449. Other FISAT II growth parameters were the amplitude of growth oscillation, C = 0.6 and the winter point, WP = 0.6, Rn = 0.3127. Mortality parameters were total mortality, Z = 479 year-1, natural mortality, M = 2.39 year-1 and fishing mortality, F was 2.40 ...
