MATEUS, L. A. de F. and ESTUPINAN, G. M.B.. Fish stock assessment of piraputanga Brycon microlepis in the Cuiabá River basin, Pantanal of Mato Grosso, Brazil. Braz. J. Biol. [online]. 2002, vol.62, n.1, pp. 165-170. ISSN 1519-6984. http://dx.doi.org/10.1590/S1519-69842002000100018.
Fork length measurements of individuals of Brycon microlepis landed and commercialized at the Porto Market in Cuiabá, MT, from May-October 1996 to May-October 1997 were used to estimate growth and mortality parameters for this species. The average estimated populational parameters were: L¥ = 705 mm, k = 0.275 year¾1, C = 0.775, WP = 0.465, Lc = 164 mm, M = 0.585 year¾1, Z = 0.822 year¾1, with F = 0.237 year¾1. Yield per recruit analysis suggests that the stock is not yet overexploited.
