Abstract A generalized method to accurately estimate the spawning fraction (S) of multiple batch spawning fish considering the duration of histological spawning markers over a wide range of ambient temperature, spawning time frequency distribution of the population, and sampling time was developed.

Female Japanese chub mackerel, Scomber japonicus, were collected in 1993 from April to June (36 days), in the water around Izu Islands, Japan, which is one of the primary spawning areas. Spawning time, spawning frequency and batch fecundity were determined by histological methods.

Spawning frequency of brood dams and sires in a marine fish stock‐enhancement hatchery
Journal of Fish Biology, 2010Parentage analysis, employing five hypervariable microsatellite markers, was used to follow spawning patterns of red drum Sciaenops ocellatus broodfish in two spawning tanks through most of a calendar year in a marine fish hatchery dedicated to stock enhancement. Five of six dams and all four sires spawned at least once during the year.

Summary Silver pomfret, Pampus argenteus, were collected by fishing with drift gillnets on one spawning ground in Kuwait waters during 1998–2000. Fish size frequency, sex ratio, maturation cycle, spawning frequency, fecundity and egg weight were assessed. The length–weight relationship differed between sexes whereby females were significantly bigger

Abstract Spawning frequency (SF) is a parameter that represents the number of spawning events per time unit, used to estimate the reproductive potential of many fish populations. We analyzed the relationship between SF and size and age of Argentine hake females from the Patagonian stock.

How does spawning frequency scale with body size in marine fishes?
Fish and Fisheries, 2021AbstractHow does fecundity scale with female size? Female size not only affects the number and size of offspring released in any one reproductive bout (i.e. batch fecundity) but also affects frequency of bouts that occur within a given spawning season (i.e. spawning frequency).

Spawning frequency and fecundity of the Antarctic krill Euphausia superba
Marine Biology, 1983The spawning frequency of Euphausia superba was estimated from observations of egg production by live individual females in captivity on board ship. The females were collected during the austral summer of 1982 near the South Shetland Islands and Elephant Island, Antarctica.

Fecundity and Spawning Frequency of the Fathead Minnow—A Fractional Spawner
Transactions of the American Fisheries Society, 1982Abstract Six pairs of fathead minnows Pimephales promelas were isolated in 0.3 × 1.5-m spawning (wading) pools partially submerged in an outdoor swimming pool from May 20 through October 20, 1980. Five pairs of fish that survived the experiment produced from 16 to 26 clutches of eggs each between May 22 and August 22.
