Abstract. This study was carried out to determine morphometric and meristic characteristics of two populations (wild and cultured) of Cichlasoma festae and to establish whether populations could be discriminated based on morphometric variability. Twenty-two morphometric and four meristic characters were used to test the hypothesis differentiation. Univariate analysis of variance (ANOVA) from 100 adult specimens showed significant differences (p <  0.05) for 21 standardized morphometric measurements out of 26 characters among the means of the wild and cultured Cichlasoma festae populations tested. Cross correlation amongst certain morphometric variables (i.e. body weight, total length, standard length, pre-ventral length, AC1, LC1 and P1) were medium-strong (r ≥  0.5), while the remaining were weakly correlated (r <  0.5). The length–weight relationship parameter b and condition factor (K) values were respectively 2.21 and 1.97 (indicating allometric growth) for cultured fish groups and 2.86 and 4.07 (p <  0.05) for wild fish groups. The condition factor values were significantly different from each other and showed that feeding of cultured fish should be improved. Both groups were accurately separated (>  80 % success rate) by linear discriminant functions that included only four morphometric measures.

Length-weight relationship (LWR), condition factor, sex ratio, gonadosomatic index (GSI) hepatosomatic index (HSI) of the smooth blaasop puffer fish Lagocephalus inermis (Temminck and Schlegel, 1850), an emerging fishery resource along south-eastern Arabian Sea were studied from 1,722 samples collected during August 2017-May 2019 from Mangalore Fishing Harbour, Karnataka, India. LWR indicated negative allometric growth [W = 0.034805L2.76 (males); W = 0.033574L2.78 (females), W = 0.033979L2.77 (pooled)] and significant difference was observed in the b value of the fishes. Sex ratio was 1:1.08. The ratio was unusually high during post-monsoon and Chi-square test revealed that the monthly sex ratio did not vary significantly throughout the year except for December and January (p<0.01). Condition factor (K) and relative condition factor (Kn ) also were not significantly different between sexes. Two peak spawning seasons were identified - NovemberFebruary and August. The GSI was highest in August (female = 8.08 and male = 5.82) and lowest in May (female = 3.32 and male = 3.49). The HSI value was found to be inversely related to GSI and was highest in May (5.21) and lowest in August (3.99). These parameters are essential pre-requisites for stock assessment and sustainable management of the fishery resource.

This is the first thorough taxonomic study on the identification and description of mullets based on their morphometric and meristic characters distributed in the coastal waters of Pakistan. The samples were collected monthly for two years from different localities of Pakistan. Forty eight parameters including thirty nine morphometric and nine meristic characters were determined. In this study 13 species belongs to seven genera are briefly described including one new record and taxonomic key for these species is developed.

A study was conducted to analyze morphological characteristics of a Schizothoracid species: Schizothorax esocinus collected from three sites of river Jhelum in Kashmir. S. esocinus is locally known as “Churru” and forms an important food element of the local population., Schizothorax esocinus is one of the most important species in the genus Schizothorax and it has continued to contribute immensely to the nutritional needs, economic growth and development of the Kashmir valley. Furthermore, this fish is very sensitive to any environmental changes so it acts as bioindicator of aquatic pollution. A total of 180 samples were taken for the study of the morphometric and meristic characters utilzing ethnic fishing gears. Thirteen conventional morphometric characters examined in the present study, showed high co-efficient of determination (R2) values ranging from 0.55 to 0.91 for district Srinagar from 0.56 to 0.92 for district Anantnag, and 0.56 to 0.98 for district Baramulla signifying that the traits were highly correlated to each other. Out of six meristic characters examined, two characters were not remarkably different (p>0.05). The fin formula of S. esocinus was devised as D, I + 5-10, P, I + 7-11, C, I + 15-23, A, I + 3-7, LL, 55-170. This study is purely aimed at studying the morphology and meristics of S. esocinus and not at estimating the length-weight relationship or condition factor.
