The Influence of Climatic Conditions of the North Atlantic on Recruitment to the Icelandic Cod Stock
The economy of Iceland depends heavily on the fishing industry, which provides more than 60% of export earnings and employs 8% of the work force. The economy, therefore, remains sensitive to declining fish stocks. In the mid-1980s, a complete collapse of the Icelandic cod stock appeared imminent and it has remained at historically low levels since. During the last three decades, the weather con...
متن کاملRecruitment Variability in North Atlantic Cod and Match-Mismatch Dynamics
BACKGROUND Fisheries exploitation, habitat destruction, and climate are important drivers of variability in recruitment success. Understanding variability in recruitment can reveal mechanisms behind widespread decline in the abundance of key species in marine and terrestrial ecosystems. For fish populations, the match-mismatch theory hypothesizes that successful recruitment is a function of the...
متن کاملCod and climate: effect of the North Atlantic Oscillation on recruitment in the North Atlantic
The impact of the environment on interannual variability in fish recruitment has proven difficult to establish empirically, and environment-recruitment correlations have often been found to break down when more data become available. This may suggest that the statistical models have failed to capture the essential explanatory variables, or that environment-recruitment relationships are non-stat...
متن کاملSpawning stock and recruitment in North Sea cod shaped by food and climate
In order to provide better fisheries management and conservation decisions, there is a need to discern the underlying relationship between the spawning stock and recruitment of marine fishes, a relationship which is influenced by the environmental conditions. Here, we demonstrate how the environmental conditions (temperature and the food availability for fish larvae) influence the stock-recruit...
متن کاملan evaluation of molecular and morphological traits of parents and their superior progeny genotypes from control cross between seeded and seedless grapevines for determination of parent-progeny relationships
grapevine is among some of the most important horticultural crops in the world and as well in iran. since last century attempts have been made throughout the world to improve grapes. research in grape breeding for the purpose of improving table grape as well as raisin traits has started since 1996 in iran with crossing some selected seedless (askary, yaghoti, bidane sefid (sultana) and bidane g...
