[cool][#0000ff]The guys from DWR stated that the Bear Lake Cutts in Bear Lake seem to live to the age of 11 or 12 years. At this point, they are only estimating that those same cutts in Strawberry will not live as long. It has something to do with "faster living and faster growth" accelerating the biological clock. Just like humans. Live hard, die young.[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]Those that die after spawning are merely succumbing to the ravages of age and stress. Many species of fish eat little and sacrifice body nutrients to their eggs or milt during spawning. The older the fish, the less they are able to survive the shock to the system...especially if they have to battle for spawning areas. Most of the stronger cutts should live to spawn several years before they go to that big pond in the sky.[/#0000ff]

[#0000ff]The kokanee, on the other hand, are the "landlocked" variety of the sockeye salmon, of the Pacific northwest. They are true salmon, living several years before spawning and then spawning only once and dying.[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]The rainbows in Strawberry are "triploids", genetically altered to make them unable to spawn successfully. However, that trait also enables them to grow big and fast, if they get enough groceries. For those who wonder why they do not want the rainbows to spawn, it is because they want to avoid hybridizing with the pure strain cutts. Cuttbows are not nearly as efficient in eating chubs as pure strain Bear Lake Cutts.[/#0000ff]
