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.
Freestyle Records. All of the fastest 50 m, 100 m, 200 m, 400 m and 800 m swimming records have been achieved in freestyle events, according to the world records posted at USAswimming.org. Cesar Cielo of Brazil holds the world record in 50 m freestyle with a time of 20.91 seconds, achieved in December 2009.
