Sampling was from March 2009 to February 2010. A total of 61 males and 71 females were measured (total length) and weighed, with data on reproductive biometry also taken. Growth parameters were determined in addition to weight–length relationships: W (t) = 0.012TL3.42, R2 = 0.96 for females and W (t) = 0.0101TL3.38, R2 = 0.94 for males. A. ginaonis females showed an asymptotic total length (TL∞) of 53.03 mm; the growth coefficient, K (year−1) 0.15, t0 (year) 1.01; and natural mortality coefficient M (year−1) 0.62. In males the value for TL∞ was 48.83 mm; for K (year−1) 0.2, t0 (year) 0.44; and M (year−1) 0.49. The relationship between absolute fecundity and fish size (total length, body weight or age) showed a strong correlation to body weight. The A. ginaonis population is threatened with extinction – and a co-management in cooperation with the local population for strong protection measures is urgently needed.
