8921 Fathead Minnow Pdf Spawn Biology Fathead minnows begin their spawning season in late spring and continue through early fall, from may to september. water temperature serves as the primary environmental trigger for spawning, with optimal conditions ranging from approximately 60°f (16°c) to 86°f (30°c). Fathead minnows are fractional spawners, meaning they begin spawning when water temperatures approach 18 °c (64 °f) and continue until they drop below that temperature in late summer.
Fathead Minnow Fishbio Fisheries Consultants Fecundity w is reported to be an intermittent, multiple spawning species. hasler et aj. (1946) and radcliff(1931) stated that this species has a lo g breeding season, possibly spawning intermittently all summer. one pair of fathead minnows produced 4,144 fingerli. > fathead minnows spawn between may and september when water temperature is 16 30°c, and usually at night. females spawn multiple times, up to 16 26 times, per season and generally release about 400 eggs for each spawning event. Water temperatures higher than 64f trigger spawning. females spawn at frequent intervals, up to several times a week. once the water warms to 84f or higher, spawning stops. fathead minnow eggs are small (1.2 to 1.6 mm). srac publication no. 120, common farm raised baitfish. This document provides information about culturing and testing the fathead minnow (pimephales promelas). it describes the appearance and life cycle of fathead minnows, and outlines procedures for obtaining, breeding, and caring for them in the laboratory.

Reproduction in fathead minnows typically occurs in late spring through early fall. these fish are fractional spawners. instead of releasing all their eggs at once, females will spawn several times during the year, producing a smaller number of eggs each time. Fathead minnow fortresses are specifically designed as a fathead minnow spawning structure, allowing a single male to claim each tube as "his" area for the season. Nearly all of a population goes through spawning in early may when water temperatures are appropriate. however, after that first spawning, females release eggs intermittently throughout the summer, with less and less frequency until mid august. Fathead minnows prefer woody structure. spawning begins when water temperatures reach 50º – 55ºf and repeats monthly until waters cool. they lay 200 to 500 eggs per spawn. stocking rate of 2 4 gallons per acre. assume 1800 – 2000 minnows per gallon. game fish illustrations courtesy of u.s. fish & wildlife service.
