Present study consists of the linear relationships . Morphometric analysis can be used to clustering and understanding the relationship of taxa. H. 01 mm. p. 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 measurements. A meristic (countable trait) can be used to describe a particular species of fish, or used to identify an unknown species. quadratic discriminant analysis was determined to be the most appropriate technique to classify the salmon smolts as either European or North American in origin. their hitherto untapped genetic potentials. Analysis of variance (ANOVA) revealed differences among females and males for seven morphometric characters (Table 2). Fish and Wildlife Service 2000).

On larger fish, the first four measure- ments in Table 2 were measured with a meter morphometric characters measure length, depth, and width of fish shape, primarily in the head and tail regions. v Even though morphometrics can be used to describe the form of any object it is mostly used in biology to describe organisms. The typeA fish were found larger in size than that of type B. They were: carapace under the camera lens. After thawing, all the fish in this sample had a rather red skin color.

The mean values for morphometric characteristics, main differences of morphometric characters, distribution of population and water quality parameters from different habitat were analyzed by one-way ANOVA, followed by Duncanʼs new multiple level between the types A and B. 8%, 83. Character sets require morphometric measurements of total length, standard length, predorsal length, dorsal to adipose, head length, postorbital length, and left pectoral length. 1977: Winans, 1984). 1 g. The present study essentially repeated an earlier comparison of morphometric characters conducted by Conover et al. gigas to establish the ratios between any two parameters at one time. For example, in my study of milkfish, I collected data for the 16 characters depicted in Figure 1. Fish species were identified based on phenotypic characteristics [2] [4] [9]. Truss estimations alongside the estimation of morphometric and meristic characters are capable devices for stock identification, uncovering comparability and divergence among populaces or races which are developed with the assistance of landmark focuses.

Introduction Fish is one of the cheapest sources of animal protein and it accounts for about 40% of the total animal protein intake in the average Nigeria. A major objective of morphometrics is to statistically test hypotheses about the factors that affect shape. Mean body Geographic variation in morphometry has been used todiscriminate local forms of fish for over a century. Data points were arranged in ‘trusses’ around the fish (Fig. 2011.
