摘要

在波罗的海，鲑鱼缺乏硫胺素(维生素B1)是由富含脂肪的鱼类饮食引起的，因此，多不饱和脂肪酸丰富，被称为M74综合征。由于其在鱼类养殖中对野生大西洋鲑鱼(Salmo salar)种群和子代产量的有害影响，建立了一个模型，从未受精卵的游离硫胺素浓度中得出卵黄囊鱼苗(YSFM)的年度雌性特异性死亡率。在M74高发年份，硫胺素缺乏的女性比非M74女性体型更大，条件因子(CF)也更大。除此之外，M74雌虫一般体型较小。M74雌虫的平均CF在大多数年份高于非M74雌虫。所编制的模型能够在不需要孵卵和孵化的卵囊苗几个月的情况下，对单个雌性鲑鱼的YSFM进行经济有效的估计，从而有利于鲑鱼种群的管理和有效利用。图形抽象

Model for estimating thiamine deficiency-related mortality of Atlantic salmon (Salmo salar) offspring and variation in the Baltic salmon M74 syndrome

ABSTRACT Thiamine (vitamin B1) deficiency of salmonines, caused by an abundant lipid-rich fish diet and consequently, the abundance of polyunsaturated fatty acids, is called the M74 syndrome in the Baltic Sea. Because of its deleterious effects on wild Atlantic salmon (Salmo salar) stocks and progeny production in fish cultivation, a model was developed to derive the annual female-specific mortality percentages of yolk-sac fry (YSFM) from the free thiamine concentrations of unfertilized eggs. In years with a high M74 incidence, thiamine-deficient females were larger, with a larger condition factor (CF) than non-M74 females. Otherwise, M74 females were generally smaller. The mean CF of M74 females was in most years higher than that of non-M74 females. The model compiled enables the cost-effective estimation of YSFM of individual female salmon, without the incubation of eggs and hatched yolk-sac fry for several months, thus benefitting the management of salmon stocks and their efficient utilization.

期刊介绍： Marine and Freshwater Behaviour and Physiology is devoted to the publication of papers covering field and laboratory research into all aspects of the behaviour and physiology of all marine and freshwater animals within the contexts of ecology, evolution and conservation. As the living resources of the world’s oceans, rivers and lakes are attracting increasing attention as food sources for humans and for their role in global ecology, the journal will also publish the results of research in the areas of fisheries biology and technology where the behaviour and physiology described have clear links to the contexts mentioned above. The journal will accept for publication Research Articles, Reviews, Rapid Communications and Technical Notes (see Instructions for authors for details). In addition, Editorials, Opinions and Book Reviews (invited and suggested) will also occasionally be published. Suggestions to the Editor-In-Chief for Special Issues are encouraged and will be considered on an ad hoc basis. With the goal of supporting early career researchers, the journal particularly invites submissions from graduate students and post-doctoral researchers. In addition to recognising the time constraints and logistical limitations their research often faces, and their particular need for a prompt review process, accepted articles by such researchers will be given prominence within the journal (see Instructions for authors for details).
