      For the meristic characters, pelvic fin ray (PVFR), caudal fin ray (CFR), anal spine (AS), pelvic spine (PVS), and total vertebrae (TV) were constant between the species and were excluded in the analyses.

In the present investigation, Intra-and inter-specific variations in morphometric indices of Mullus sermuletus and Mullus barbatus, from Mediterranean Sea at Alexandria, Egypt, were revealed.

Morphometric and meristic analyses are part of important rigorous tools used to differentiate closely related species of organism having huge similarity indices of various parameters [2].

Morphometric characters are not only essential to the understanding of the taxonomy but alsoFile Size: KB. Morphometric characters and meristic count of a fish, Garra gotyla gotyla (Gray) have been studied from Ranjit Sagar Wetland. Monthly sample collection of Garra gotyla gotyla was conducted for the study of morphometric characters and meristic Size: 1MB.

Six meristic and 16 morphometric characters were counted and measured. The results showed a significant difference between the studied species in all morphometric traits except the pectoral fin.

morphometric and meristic characteristics or DNA analysis. Morphometric characteristic is the character illustrating the body shape, while meristic character counted number, series or structure. Both morphometric and meristic characters are mostly used to File Size: KB. their hitherto untapped genetic potentials.

Morphometric and meristic characters of fish are the measurable or countable characters common to all fishes. Landmarks refer to some arbitrarily selected points on a fish’s body, and with the help of these points. Meristic and morphometric phenotypes of the spring-spawning stock of ciscoes (Coregonus artedii) from lac des Écorces were compared with those of fall-spawning stocks from the same drainage spring spawners show almost complete nonoverlap in gillrakers compared with fall spawners (averages of andrespectively).Cited by:   Multivariate discriminant function analyses were performed on 9 morphometric and 11 meristic characters of capelin (Mallotus villosus) samples at Île aux Coudres in the St.

Lawrence estuary; Sept Îles, Natashquan, and Grande Rivière in the Gulf of St. Lawrence; Southeast Shoal on the Grand Banks; and Herring Neck, Notre Dame Bay, Newfoundland.

Analyses of meristic characters Cited by: morphometric indices (relative to total length, TL) and meristic characters were estimated. The allometric coefficients of the raw morphometric characters and their relationships with fish size (TL) were estimated using power function equation and linear regression model respectively.

The type of. Multivariate analyses of 11 meristic and 33 morphometric characters were also evaluated, including the distance from the end of the mouth opening to the most anterior dorsal fin (), distance from the anal fin base to the anterior part of the caudal fin () and the base length of the dorsal fin () which contributed to the separation of by: Meristic traits are often described in a shorthand notation called a meristic formula.

Meristic characters are the countable structures occurring in series (e.g. myomeres, vertebrae, fin rays) in fish. These characters are among the characters most commonly used for differentiation of. Meristic and morphometric traits are used to identify fish A meristic is a countable trait, such as number of gill rakers or number of dorsal fin spines.

Morphometrics examines the size and shape using a measurable trait, such as standard length or wet weight, which can be gauged as a length, mass, angle or ratio of other g: book.

Meristics are often combined with details onanatomy and morphometrics. Meristic characteristics of a fish canbe compared to those listed in key reference books, descriptionsand in dichotomous keys to help us work out which species we arelooking at.A meristic study is an often difficult task, as counting the featuresof a fish is not easy.

collected regarding the morphometric and meristic characters. Due to the vastness of the population, we decided to select a sample from the population.

A total of 21 variables which comprises 5 meristic and 16 morphometric characters were analyzed. As we found that the counts for 3 variables namely dorsal fin (DF), anal fin (AF) and. The meristic characters like dorsal fin rays, anal fin rays, Lateral line scales, gill rakers on lower arm and scales in transversal line were counted.

No sexual dimorphism was found in Pomadasys maculatus. In the present study the average total length of females were mm TL and the average total length of males were mm by: 2.Twelve morphometric characters and body weights of the fish were measured to an accuracy of mm and g, respectively (Table 2).

In total, 9 meristic characters (dorsal, pectoral, pelvic, anal, and caudal fin rays, lateral line scales, scales above and below the lateral line, and vertebra counts) were analyzed. Eleven landmarksCited by: Morphometric and meristic characters have often been used in discrimination and classification studies by statistical techniques (Pope and Hall, ; Jahnson and Barnett, ; Agnew, and Avsar, ).

Considering the need of an investigation the present study was undertaken to compare the morphometric and meristic discrimination of Channa.
