28-pound striper "landed" at Lake Powell
Wayne Gustaveson with the Wayne's Words Lake Powell Fishing page and Lake Powell Project Leader for the Utah Division of Wildlife Resources sent in this fun story about a big striper "landed" at the massive reservoir.
Early Saturday morning, June 14, a call came stating a big striper had just been caught at the mouth of Warm Creek. It took about 20 minutes to get there but we soon found a boat at the corner of Warm Creek and the main channel. Adam Jones and Deborah Williams were right there and when we got in range Adam held up a huge striper. We got out of the wind and headed to shore where we could get the full story.<
Adam and Deborah were out at dawn fishing along Warm Creek Wall when they noticed a surface disturbance. As they got closer it proved to be a giant striper thrashing on top. They got close enough to net the fish and then tried to resuscitate the fish and release it. But it was to no avail, the big fish succumbed within minutes of capture. They measured the fish using hand widths and came up with 45 inches. That's when I showed up and began discussing options.
Adam would like to have the fish mounted as it was the biggest fish he ever "caught". But it is entirely possible to make a fiberglass mount by just supplying dimensions and a picture to the taxidermist. It was determined that I would take the fish, determine exact measurements, and perform a necropsy to determine cause of death. I put the big fish on ice and headed back to the lab.
This fish was 44 inches long and weighed 28.75 pounds (certified scales) with a girth of 25.5 inches.
Most striped bass of this length exceed 30 pounds but this one had an empty stomach except for 3 carp spines. It had been eating recently but the mostly empty stomach, which was 14 inches long, did not add an extra pound or two which is common when the stomach is full. That also explains why the girth was 2 inches smaller than other stripers of this length.
The cause of death was likely spawning stress. The 10-inch long ovaries were spent suggesting this fish had just completed spawning. Full ripe ovaries can weigh 2-3 pounds which would add more weight and girth to this fish.
Striped bass are a marine fish that are adapted to life in the ocean. As they mature they seek water temperature in the mid 60s. Juvenile stripers can survive well in warmer water. This genetic change with age, separates large and small stripers and protects small fish from predation by larger ones.
In fresh water the opposite is true. When adult stripers mature and are forced into deeper, cooler water it is adult fish that struggle. Shad live in warm water where juvenile stripers reside. When adults are forced to leave the warm zone their food choices become limited leaving juvenile stripers on top with shad and the competitive advantage. If adult stripers are not large enough to eat 1-pound carp and catfish then they become malnourished. This explains why there are so many large, lean fish in certain years.
But this trophy fish was healthy and well nourished. Striped bass are surface spawners so they must abide the warm water during spawning. If they stay in 75+ degree water for an extended time, lactic acid builds up in the muscles beyond the capacity of the fish to recover. This is the cause of death of most trophy fish that are found dead on the surface.
