Conversely, commercial samples are collected throughout the fishing season, but may be more geographically limited due to the concentration of fishing effort in the most productive habitat.Īs proposed at the 19th Session of the IPHC Scientific Review Board (SRB019) ( Webster 2021), our approach is to combine data from the commercial sampling with that from the FISS sampling in order to estimate length-net weight relationships that are as broadly applicable as possible. While the FISS data are typically collected in a spatially comprehensive manner within each IPHC Regulatory Area, they are temporally restricted to the May-September summer period. The current IPHC commercial Pacific halibut sampling program and the IPHC Fishery-Independent Setline Survey (FISS) weight sampling provide us with two independent data sources to use in estimating contemporary length-net weight relationships.
