Abstract Morphometric and meristic characters are very important for the identification of any fish specimen. The present study aims to describe the morphometric and meristic characters of the indigenous fish Crossocheilus diplochilus (Heckel) from Dal Lake. This fish is commonly known as Kashmir latia and is called tether locally. In the present study, the material analyzed was 70 specimens ranging in size from 6.9–13 cm (TL) with a mean length of 10.8 cm and a weight range of 3.2–24.0 g with a mean weight of 10.1 g. The parameters with the highest correlations with total length were standard length and fork length at 0.983 and 0.989, respectively. Correlation analysis showed that all morphometric characters changed proportionally as total length increased. The meristic counts analyzed in the present study remained constant in fish of different sizes indicating that they are independent of body size. The study of morphometric characters is very important to determine the growth rate of these fish, which, in turn, is required to properly manage its populations.

Abstract Schizothorax labiatus (McClelland) is considered to be one of the most economically important fish species among Schizothorax spp. A total of twenty-four morphometric and five meristic characters were examined; 18 of the morphometric characters as percentages of total length and four characters as percentages of head length were studied. It was found that the characters of standard length, fork length, pre pelvic length, pre anal length, and pre dorsal length had the highest correlations with total length, whereas dorsal fin height followed by caudal fin height had the lowest correlations. In percentages of head length post orbital length had the highest correlation whereas snout length had the lowest correlation. Overall, the results revealed that all the morphometric characters exhibited linear relationships and depicted significantly (P < 0.05) high degree of correlation, while the meristic characters counted were constant in all sizes of S. labiatus, indicating that they were independent of body size. The study provided basic information that will be useful for fish biologists and researchers in the future management and conservation of this fish species.

The present study analysed the morphometric and meristic characters of Otolithoides pama (Hamilton, 1822) collected from the Hooghly-Matlah estuarine system of West Bengal, India. A total of 618 specimens (298 males and 320 female) were collected during the period of 18 months from November 2016 to April 2018 with length ranging from 100-384 mm and weight 7.29-470.71 g, respectively. The analysis of 14 morphometric characters revealed that standard length has the fastest growth rate when compared to total length, while eye diameter has the lowest growth rate when compared with head length. A high degree of significant positive correlation with the ‘r’ values ranging from 0.978 to 0.997 was observed among different morphometric characters of O. pama. Among nine of the meristic counts, the coefficient of variation was found to be highest in anal fin rays (6.31%) and minimum in dorsal fin rays (1.12%). Based on the meristic counts, the fin formula of O. pama from the present study can be described as B. 7 , D. 9-10/1/44-45, P. i/16-17, V. 1/5 , A. 2/7-8, C. 19-21, L. 48-52. The number of gill rakers on the first left gill arch ranged from 19-21.

AbstractThe aim of this study was to determine the growth features of European perch (Perca fluviatilis L., 1758) inhabiting Lake Ladik. A total of 858 individuals were caught. The total length and weight ranged from 8.2 to 27.5 cm and from 7.16 to 365.20 g, respectively. The age of the females ranged between 1 and 7 years and the age of the males ranged from 1 to 5 years. The female to male ratio was 1:0.19. The von Bertalanffy growth equation parameters were determined as L∞=41.27 cm, W∞=1251.40 g, K=0.10 (year−1), t0 (year)=−1.98 for all samples. Length-weight relationship was calculated as W=0.0047TL3.358 for all specimens. Length-length relationships (total length-standard length, total length-fork length, standard length-fork length) were highly significant (r2>0.98). The mean condition factor value was obtained as 1.28 for all fish. Condition factor showed statistically significant increase according to length classes.

Intraspecific Crossing

Intraspecific crossing of giant gouramy was done to get better hybrid population. This study was conducted to evaluate the hybrid vigour or heterotic value of the hybrids line, especially for growth rate character. Besides that, we want to know the effect of hybridization on performance of phenotypic variability. Two days post hatching age larvae of four populations i.e. Bastar and Blue-saphire strain, F-1 hybrid and F-1 hybrid reciprocal, were used in this experiment. All fish were reared in aquaria for 30 days period in indoor hatchery. The fish were fed with live food such as Moina and Daphnia for the first ten days, followed by Tubifex for the second ten days and finally, commercial feed were given until the end of the study. The collected data were total length, standard length, and body weight of each population. The results showed that the phenotypic variability of the hybrid population was higher than that of inbred population. Hybrid population from female of Bastar and male of Blue-saphire has better growth than both of its parents. Heterotic values of total length, standard length, and body weight of the hybrid population was 9.5%, 2.9%, and 15.6% respectively. Maternal effect was detected in hybrid population.

Morphometric characters and meristic count of a fish, Tor tor (Hamilton Buchanan) have been studied from river Ujh, a tributary of river Ravi in District Kathua, (J&K). Collection of samples on monthly basis was conducted for the study of morphological characters of Tor tor. Present study shows some deviations with respect to few morphometric characters and meristic counts that have been aptly discussed in the following discussion. The positive correlation has been observed between total length and external body parts. The highly strong correlated body parameter in relation to total length is standard length (r = 0.98) and least correlated with eye diameter (r = 0.32) and the highly correlated external body part in relation to standard length is caudal length (r = 0.96) and least correlated part is eye diameter (r = 0.35) and also strong correlation was observed between head length and maximum body depth (r = 0.93) and least correlation between head length and eye diameter (r = 0.23). The correlation analysis shows that all the morphometric characters change proportionally with increase in the total length. These results act as baseline data on morphometry of Tor tor which helps in easy identification and will be beneficial for the development of conservational strategies of the natural stocks of Tor tor in river Ujh, Kathua (J&K).

Twenty-two morphometric and nine meristic characters of 280 Gudusia chapra (Total length 30-210mm) and 264 Gonialosa manmina (Total length 40-150 mm), the two important clupeids from the Kaptai lake, were studied during 1996-1997 to detect the plastic and non-plastic characters. Wide and medium range characters are plastic characters and hence are controlled by the environment while the narrow range characters are genetically controlled and non-plastic and hence can be used for differentiation of stock or sub-species. Three different categories of morphometric characters of the two species were recognised, viz., wide range, medium range and narrow range. Wide range morphometric characters varied within the range of 21.47% to 140.62% in the case of G. chapra and 24.04% to 87.19% in the case of G. manmina while the medium range characters varied within the range of 11.76% to 13.75% in the case of G. chapra and 11.55% to 18.92% in the case of G. manmina and less than 10% range characters were designated as narrow range. The relationships between the different morphometric characters (both dependent and independent variables) were found to be linear and in all the cases the relationships were found to be highly significant (P< 0.001).

Morphometric and meristic analysis of ladyfish, Elops machnata, were used to discriminate stocks along the Southeast and Southwest coast estuaries of India. Morphometric and meristic analyses showed a similar pattern of differentiation between E. machnata stocks and revealed a clear discreteness of two groups, an East coast (Marakanam, Parangipettai and Muthupettai) population and a West coast (Cochin) population. Higher total length (TL) (28.00 ± 7.043 cm), fork length (FL) (89.27 ± 2.201% TL) and standard length (SL) (81.77 ± 2.582% TL) were recorded in Cochin population and they were significantly different from the other three populations. Meristic counts were relatively homogenous in all the studied populations. No significant variation was found in counts of dorsal fin ray (DFR), anal fin ray (AFR), pectoral fin ray (PFR) and pelvic fin ray (PLFR). The first and second components (PCA analysis) accounted for about 92.2% of variation in all the morphometric characters. Among them, pre pectoral length (PPL) and pre dorsal length (PDL) showed high loading values in PC1 in all four populations. The overall random assignment of individuals to their original group was higher in morphometric than in meristic analysis. Such a presumption could be authenticated henceforth with molecular markers. Hence, further studies, using molecular markers are still required to precisely evaluate the genetic structure of E. machnata along the Indian coast.
