CHAPTER 6 I. Introduction Observer programs provide an excellent way to collect biological specimen information for use by fisheries biologists and stock assessment analysts. Observers in the WCGOP are asked to collect fish lengths, weights, sexes, otoliths, viabilities, tags, and scales in an effort to improve understanding of various fish stocks. Fish lengths, sexes and otoliths are used to determine the relative abundance of fish year classes and the occurrence of the various year classes in commercial fishing landings. These specimen collections are also used to estimate the sexual composition of fish year classes, determine differential growth rates between sexes, and to provide length to age ratios for use in stock assessments. Pacific halibut viabilities (injury data) are used to assess the mortality rate of Pacific halibut due to commercial fishing. The injury data collected by Observers are analyzed by staff from the International Pacific Halibut Commission (IPHC) and used to estimate yearly mortality rates. Information from tagged fish and crabs are used by a variety of educational institutions, state agencies, and federal agencies. Fish are tagged to study fish migration, stock separation, fishing related mortality, and population dynamics. Data from tagged fish is vital to the success of these studies. Scales are collected from salmon to verify species identification. Salmon are often extremely difficult to identify when caught either because of damage incurred during gear retrieval or strange coloration due to the proximity of spawning. 6-2 1/30/2004
CHAPTER 6 II. Data Collection Priorities Due to potential data collection time constraints, Observers are asked to prioritize the collection of biological specimen information by species and information taken. In addition, biological sampling should only be undertaken after collecting comprehensive catch and species composition information. Biological Specimens are taken from DISCARD only. Biospecimen data collection in order of priority: 1. Tagged Fish • Collect length, weight, sex, and tag. • Collect otoliths if appropriate (see details below). 2. Salmon • Collect length and sex. • Collect snout if adipose fin is missing (tagged salmon). • If possible, collect weight. • Collect scales if appropriate (see details below). 3. High Priority Rockfish Species and Lingcod • Collect length and sex. • If possible, collect weight and otoliths. 4. Pacific Halibut • Collect length and viability. • If possible, collect weight. 1/30/2004 6-3
