Stocks' yield and size per recruit are widely used to provide fisheries management guidance. This study provides details for analyzing the composite (i.e. age-aggregated or stage-structured) yield per recruit (CYPR) model CYPR14, and proposes CYPR14 as a

Impact of the natural mortality (M) variability on the evaluation of the exploitable stock of sardine, Sardina pilchardus (Actinopterygii: Clupeiformes: Clupeidae) of the central region of the Algerian coast [PDF]
Background. The landings of sardine, Sardina pilchardus (Walbaum, 1792), captured by purse seiners in the central region of the Algerian coast, Mediterranean Sea have been decreasing over the last decade.

A comparison study of age- and length-structured yield-per-recruit models [PDF]
Les modeles de rendement par recrue sont communement utilises pour orienter la gestion et pour estimer les points de reference biologique, F 0.1 ou F MAX . Bien que ces modeles soient habituellement structures en âge, leurs parametres sont plus directement lies a la taille qu'a l'âge.

The influence of sample distribution on growth model output for a highly-exploited marine fish, the Gulf Corvina (Cynoscion othonopterus) [PDF]
Estimating the growth of fishes is critical to understanding their life history and conducting fisheries assessments. It is imperative to sufficiently sample each size and age class of fishes to construct models that accurately reflect biological growth ...

ABSTRACT Background Combined oral contraceptive (COC) use in obese adult women dramatically increases the relative risk of developing a pulmonary embolism (PE). The risk of a PE in obese adolescent females taking contraceptives is currently unknown. The purpose of this investigation was to determine the effect of body mass index (BMI) and contraceptive

ABSTRACT Background Type 1 plasminogen deficiency (PLGD‐1) is an ultra‐rare autosomal recessive disorder caused by variants in the PLG gene and affects approximately 1.6 individuals per million. The condition is characterized by decreased plasminogen levels and impaired function, resulting in fibrin‐rich lesions on mucous membranes throughout the body.

The effect of including length structure in yield-per-recruit estimates for northeast Arctic cod [PDF]
Abstract Kvamme, C., and Bogstad, B. 2007. The effect of including length structure in yield-per-recruit estimates for northeast Arctic cod. – ICES Journal of Marine Science, 64: 357–368. For northeast Arctic cod (Gadus morhua), traditional age-based estimates of yield per recruit (YPR) are compared with alternative, though comparable ...
