An evaluation of recent changes in the population dynamics of Southern Gulf herring / by G.H. Winters and J.A. Moores.: Fs70-8/79-28E-PDF

"Landings from this stock complex decreased from peak levels of 300,000 m tons in 1970 to a low of 37,200 m tons in 1974. Research studies (Winters and Hodder 1975) have revealed that the precipitous decline in abundance during the 1970's was due to a combination of moderate growth overfishing and successively poor recruitment to both spawning components (spring and fall) following two very large but apparently anomalous year-classes produced in the late 1950's. More recent studies (Winters et al. 1977, Winters 1978) have indicated divergent recruitment patterns in the two spawning components during the last decade, resulting in a shift in predominance towards spring-spawners"--Introduction.
