Abstract A simple method to estimate the parameters of the Ricker stock-recruitment model is described. The method is based on the Beverton and Holt yield per recruit model, as a function of fishing mortality, which can be used to describe the stock-recruitment relationship of an exploited stock even when the data are limited to 1 year of estimates ...

Abstract Yield per recruit and spawning stock biomass per recruit models were developed to study the interaction between the Taiwanese longline and South African baitboat fisheries for South Atlantic albacore. The Taiwanese longline fleet was found to have a logistically-distributed selectivity pattern with many age classes contributing significantly

Size-Structured Yield-per-Recruit Simulation for the Florida Gill-Net Fishery for Spanish Mackerel
Transactions of the American Fisheries Society, 1988Abstract We estimated the effects of gill-net mesh size regulations on the yield per recruit of Spanish mackerel Scomberomorus maculatus in Florida. Yield per recruit was calculated with a simulation model that incorporated seasonal fishing rates by sectors (recreational and commercial) and size-varying availabilities of fish to the gear and retention ...

Analysis of Potential Yield per Recruit for Striped Bass Produced in Chesapeake Bay
North American Journal of Fisheries Management, 1984Abstract The yield of striped bass (Morone saxatilis) in biomass and numbers was estimated for constant recruitment of young fish into the population on the basis of vital statistics of the Maryland stock. Separate computations were performed for males, females, and sexes combined.

Abstract We evaluated the effect on yield per recruit of mortality from catch and release of fish smaller than a legal minimum length. Catch-and-release mortality reduces the potential effectiveness of minimum size limits for increasing yield per recruit by an amount that depends on the fishing mortality coefficient, the minimum size limit, and the ...

Estimation of yield per recruit when growth and fishing mortality oscillate seasonally [PDF]
ICLARM Fishbyte, 1991 A general form of the yield equation is presented. This is used to investigate the effects of seasonal growth oscillations on estimation of yield per recruit. The results show that these effects will be strongest in short-lived organisms such as penaeid shrimps.

Yield per recruit of the Tambaqui, Colossoma macropomum Cuvier, in the Amazonas State, Brazil
Journal of Fish Biology, 1983The tambaqui, Colossoma macropomum, is the most important fish landed at Manaus by the fishery in the Amazonas State, Brazil. Population parameters have been estimated for this stock, which are: L∞= 107·3 cm (t.l.), W∞=32 kg, AT=0·227 year‐1, M=0·45 year‐1.
