Description Taking advantage of published data on life-history traits and short-term information on fishery parameters from 3132 records for 644 fish stocks along the coast of India, we calculated
resilience (R) and vulnerability (V). Further, we developed an Index of Resilience and Vulnerability (IRV) for 133 species of tropical finfishes, crustaceans, and molluscs. Using 7
resilience and 6 vulnerability attributes, two-dimensional scatter plots of the resilience and
vulnerability scores were generated and the Euclidean distance and angle from the origin to
each point were calculated to determine IRV and the effect of fishing on fish species. By
ranking the species, the top 10 highly resilient, highly vulnerable, and high-risk species (low
IRV) were identified. While small-sized species with fast growth rate and low trophic level
were among the highly resilient species, large predatory species such as sharks and barracudas were among the highly vulnerable and high-risk species. More than 100 of the 133
species were resilient-yet-vulnerable, and most crustaceans showed high resilience. Differences in IRV scores among species within the same family were discernible, indicating the
differences in the biological characteristics and response to fishing. Sensitivity analysis indicated that an abridged IRV with 6 attributes works similar to 13 attributes and can be used in
data-deficient situations. Comparison of R and V of IRV with other assessments showed different results because of divergences in the objectives, number and types of attributes, and
thresholds used. These assessments do not convey the same information and therefore
great care must be taken for reproducing these frameworks to other fisheries. The results of
IRV analysis can be useful for stock assessments and in developing effective management
measures in combination with other complementary information.
