Abstract

The body shape, body yields and morphometric ratios are important for species characterization and evaluation of their productive potential. The aim of this study was to determine the morphometric reasons, the body yields and correlations for male and female suruvi, Steindachneridion scriptum. It was analyzed 30 males and 30 females, and length and weight measurements were made. Carcass yields and morphometric relationships were calculated. The design was complete randomized. Data were subjected to analysis of normality; variance and means were compared by t test and Mann Whitney test. The average total weight of males was 1,583.50 ± 263.79 g, while the total weight of females was 1,606.66 ± 185.34 g. The total lengths were 53.42 ± 2.64 cm for males and 53.35 ± 1.98 cm for females. Average total weight and total lengths were similar between the sexes (P>0.05). Dress out yields of 65.54 ± 1.36% (males) and 65.71 ± 1.20% (females) and those of edible portions of 41.99 ± 1.66% (males) and 41.93 ± 2.05% (females) did not differ significantly between the sexes (P>0.05). The percentage of head relative to the total weight was significantly higher in males (17.67 ± 1.24%) than in females (16.90 ± 0.85%). The weight of the viscera such as the percentage relative to the total weight were significantly higher in females. The species has no body yields and morphometric characteristics limitations for commercial production.
