Based on otolith microchemistry Nursery grounds supplying spawning locations
the populations e.g. 1) How many populations? 2) Spatial and temporal distributions 3) Mixing hypothesis, e.g. diffusion/overlap 4) Biological characteristics (SRR, growth rate, natural mortality, fecundity, …) 5) Current status, virgin biomass, BMSY, etc… 6) Variability in the above, trends/random/stationarity/non-stationarity and the fisheries e.g. 1) Temporal and spatial overlap with stocks 2) Selectivity by age 3) Management measures
1. No. Populations - 4 2. Spatial distributions of stocks
