Age determination of archer fishes (Toxotes jaculatrix and Toxotes chatareus) inhabiting Malaysian estuaries

In this study the most common bony structure (scales) and method was investigated for age determination of archer fishes. A total of 85 specimens of archer fishes (Toxotes chatareus and Toxotes jaculatrix) from the estuaries of South Johore, Malaysia were examined for age. Scale length is linearly p...
