Sea Lamprey

lukeake4144 — 2024-11-08 16:24:30 UTC

Could sea lamprey cause the trout population to decrease?

2024-11-08 16:24:34 UTC

During the dissection, the female lamprey had a BUNCH of eggs. It was probably at least 10,000 so if they produce that much baby lamprey they could be the main cause of the trout population decreasing.

Conclusion: What is causing the trout population to go down?
