The present study examines the correlations between fifteen morphometric and ten meristic characters and total length (TL) of males, females, and combined sexes of Alepes vari (Cuvier, 1833) collected from Karachi fish harbor, West Wharf of Karachi Coast. Statistical analyses of linear regression relationships show mostly strong correlations (r[greater than or equal to]0.70; p0.05) with total length (TL). Hence, according to our present results, there is a direct relationship between the total length of fish and all morphometric characters, which were found to be the best indicators of positive allometric pattern growth in fish. Moreover, analysis of the 2-sample t-test revealed (t-test; p>0.05) that no sexual dimorphism was reported in Alepes vari. Thus, our present study could be valuable in systematic classification, sexual dimorphism, and management of this species on the Karachi coast. Keywords: morphometric, meristic characters, linear regression relationships, Alepes vari. O presente estudo examina as correlacoes entre 15 caracteres morfometricos e 10 caracteres meristicos e comprimento total (CT) de machos, femeas e sexos combinados de Alepes vari (Cuvier, 1833), coletados do porto de Karachi, West Wharf, na costa de Karachi. As analises estatisticas das relacoes de regressao linear mostraram, principalmente, correlacoes fortes (r [greater than or equal to] 0,70; p < 0,05) entre o CT e a maioria dos caracteres morfometricos em machos, femeas e sexos combinados, exceto a altura da nadadeira peitoral e o comprimento da base da nadadeira pelvica, enquanto os caracteres meristicos foram constantes, indicando correlacoes fracas ou negativas (r [less than or equal to] 0,50; p > 0,05) com o CT. Portanto, de acordo com nossos resultados, existe uma relacao direta entre o CT dos peixes e todos os caracteres morfometricos, que foram considerados os melhores indicadores de crescimento do padrao alometrico positivo em peixes. Alem disso, a analise do teste t de duas amostras revelou (teste t; p > 0,05) que nenhum dimorfismo sexual foi relatado em A. vari. Assim, o presente estudo pode ser valioso na classificacao sistematica, dimorfismo sexual e ma
