Predicting Paddlefish Roe Yields Using an Extension of the Beverton–Holt Equilibrium Yield-per-Recruit Model

North American Journal of Fisheries Management, 2013
Abstract Equilibrium yield models predict the total biomass removed from an exploited stock; however, traditional yield models must be modified to simulate roe yields because a linear relationship between age (or length) and mature ovary weight does not typically exist. We extended the traditional Beverton–Holt equilibrium yield model to

Effects of ageing errors on estimates of growth, mortality and yield per recruit for walleye pollock (Theragra chalcogramma)

Fisheries Research, 1987
Abstract The effects of ageing errors on estimates of growth, mortality and yield per recruit for walleye pollock (Theragra chalcogramma) were investigated by using Monte Carlo simulation. At current levels of normally distributed ageing errors (between and within reader), the bias in the von Bertalanffy growth parameters, L∞ and K, and survival rate,

Yield per recruit of the Tambaqui, Colossoma macropomum Cuvier, in the Amazonas State, Brazil

Journal of Fish Biology, 1983
The 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.

Short-term hooking mortality of tailor (Pomatomus saltatrix) in Western Australia and the impact on yield per recruit

Fisheries Research, 2002
Abstract Recreational catches of tailor (Pomatomus saltatrix) in Western Australia are regulated by a size and daily catch limit. Short-term mortality rates of angler-caught tailor were investigated to determine the effectiveness of these management strategies in coastal and estuarine waters around Perth, WA.

[Estimation of biological parameters and yield per recruitment for Coilia nasustaihuensis in Dianshan Lake, Shanghai, China].

Ying yong sheng tai xue bao = The journal of applied ecology, 2015
Coilia nasustaihuensis is the most abundant species in Dianshan Lake and plays an important role in the lake ecosystem. From July 2010 to August 2011, a total of 3107 samples of C. nasustaihuensis were collected from Dianshan Lake. Based on length data of these samples, ELEFAN I technique was employed to estimate growth and mortality parameters, and ...

Growth, mortality and yield per recruit model of picarel (Spicara smaris L.) on the eastern Turkish Black Sea coast

Fisheries Research, 1995
Abstract The growth and mortality of the picarel, Spicara smaris (L., 1758), were determined from specimens collected on the eastern Turkish Black Sea coast during September and October 1991 and 1992. From the length-age data for both sexes and all areas combined, the following population parameters were estimated: length-weight relationship, W =
