Fecundity and Spawning Frequency of Caged Bluntnose Minnows–Fractional Spawners
Transactions of the American Fisheries Society, 1983Abstract Eleven pairs of bluntnose minnows Pimephales notatus produced from 7 to 19 clutches of eggs between May 27 and August 28. Clutches ranged in size from 5 to 547 eggs. Average clutch size ranged from 93 to 239. The total number of eggs spawned per pair ranged from 1,112 to 4,195 (mean = 2,396).

Optimum escapement computed using Ricker's spawner-recruit curve
Fisheries Research, 1994Abstract The principal use of Ricker's curve is to predict the optimum number of fish allowed to escape the fishery and spawn. I suggest that the error-structure for Ricker's curve is often approximate lognormal recruitment, multiplicative normal measurement error for escapement, and additive normal measurement error for yield. Fitting Ricker's curve
