| Summary, etc |
Fisheries research is aimed at developing strategies for managing the resources for sustainability. Stock assessment is the tool employed in the determination of resources/ stock health status based on which management strategies are decided. Information on age of fishes is used in fish stock assessment models for the estimation of recruitment, growth and mortality parameters, which plays a fundamental role in the assessment of commercial marine fish resources. The conventional techniques used for estimating age of fishes involve tracing of modal progressions of length groups in the population through time. Age and related estimates for the same species by different workers with the help of the length frequency method has been found to be highly subjective. This necessitated validation of age estimates obtained by conventional means using a robust and dependable method. Findings on the formation of marks on the animal’s hard parts (calcified structures) on a regular and sometimes annual basis, formed the basis for the use of these structures for precise age determination in fishes. Recently, age information derived from calcified structures are in use for validating the age estimate obtained from other methods. The number of age validation studies has increased over the last several years following standardization and simplification of hard parts based ageing process. Considering the importance of this technique the process involved were compiled in this book for the benefit of researchers. |
