In 1959, statewide salmon harvests were about 25 million salmon a year. In 1999 (forty years later) Alaska's commercial wild salmon catch was 214 million fish, the second largest in the state's history.
Interval Basics. Swim times vary according to age and ability. In general, average lap swimmers in a 100 m pool comfortably complete a 100 m swim in two minutes. A swimmer who has an easy interval time of two minutes would consider a 100 m time of one minute 30 seconds very good.
On my Master's swim team, the slow lane (where I swim) does about 1000 yds per half hour if we're swimming freestyle (fewer yds for other strokes per half hour). The fastest lane does 1000 yds in 20 minutes or less. So my lane aims for 4,000 yds in 2 hrs, while the fast lane aims for 5,000+.
