Changes in lake sturgeon spawning periodicity is associated with prior reproductive effort.

ABSTRACT: Long-lived iteroparous organisms vary resource expenditures toward migration and reproduction in response to individual physical factors and conspecific interactions, which can affect future reproductive timing and interval. Reproductive actions can lead to trade-offs associated with allocations to current vs. future reproduction, including longer reproductive interval, require additional study. The objective of this study was to evaluate associations between physical stream characteristics, individual behaviors, and breeding demographics and spawning periodicity in lake sturgeon (Acipenser fulvescens). We used Radio Frequency Identification tags to monitor spawning migration by male (N = 1931) and female (N = 683) adults over seven consecutive years (2016 through 2022) in the Black River,
