This document provides a summary of a minor project on the classification of fish. The project was presented by Rakesh Das for his 4th semester studies in the Department of Food Processing Technology at Falakata Polytechnic under the guidance of Mr. Dibyalok Raha. The presentation classifies fish based on their location, life cycle, and metabolism. It discusses pelagic and demersal fish classified by location, and anadromous, catadromous, amphidromous, potamodromous, and oceanodromous fish classified by their life cycle patterns. It continues with classifications based on fish metabolism but does not provide examples.

Example:-

4.  Classification based on life cycle of fish:-
 Anadromous fish:-
Example:- Salmon, American shad,
Smelt, Hickory shad, striped bass,
Lamprey, Gulf sturgeon.
 Catadromous fish:-
Example:- American eel,
European eel, Shortfin eel, Inanga,
Longfin eel.
 Amphidromous fish:-
Example:- : River goby,
Mountain mullet, Dolly Varden,
Sirajo goby, Bigmounth sleeper.

5.  Potamodromous fish:-
Example:- Sciklefin redhorse, Laka
sturgeon, Robust redhorse, flathead
catfisn.
 Oceanodromous fish:-
Example:- Black grouper, Mutton snapper,
Goliath grouper.
