Identification of Fishes: To identify species of a fish following tools are used.  Morphometric - measurements relative to length  Meristic - counts  Anatomical traits - shape, presence/absence  Color patterns

Meristic: (Counting) 1. Scale counts: Lateral line scale count Scales above lateral line Scales below lateral line Scales before dorsal fin

2. Fin (Ray and Spines) count:  Spines: Single‐shafted, entire composition, designated by roman numerals.  Soft rays: Bilaterally paired, segmented, branched, flexible, designated by Arabic numerals.  Fin formulae: Counting of each fin ( number of Spines and Rays)  A fin may contain them both.  Example: D XIII 12, A III 15, P 6, V I 6, C 9  (D dorsal, A – anal, P – pectoral, v – ventral or pelvic, C – caudal).

Morphometric: (Measurement)  Standard length (From snout to base of caudal fin)  Head length ( Snout to Operculum)  Snout length (Diatance between eye orbit and mouth tip)  Dorsal Fin Length  Pelvic fin length  Pectoral fin length  Caudal fin length  Anal fin length

Eye orbit Length Upper jaw length Body depth  Pointed dividers or dial‐reading calipers are used. Measurements are recorded in% of Standard length.

Procedure:  Take sample fish, Take more then one fish as sample.  Collect Required Standard data bout fish in published form.  Take observation of Morphometric and meristic.  Tele your observations with standard readings.
