1.2. Proximate composition
Unit 1- Principles of Fish Preservation
1.2. Proximate compositionWhat is proximate composition?
- Relationship of the major chemical constituents in terms of proportion to the whole weight expressed in percentage
What are all the parameters affecting the proximate composition of fish?
- Body part
- Species
- Age
- Sex
- Size
- Sexual maturity
- Habitat
- Fishing season
- Note: Protein content shows less difference in different fishes, whereas lipid content shows wide variations.
- Fat content decreases from tail towards head and from ventral towards dorsal portion.
- Fin fishes differ from terrestrial animals by the presence of dark muscle. Dark muscle contains more fat than white meat in some fatty fishes
