The species distribution of commercially exploitable fish has been mapped to 1/4 scale ICES Rectangle unit as a value catch per unit effort calculated from the Irish Groundfish Survey haul observations catch numbers.

]]>Spawning area, spawning grounds and spawning beds are considered the locations where commercially important species of fish leave their eggs for fertilisation. Spawn consists of the reproductive cells (gametes) of fish, some of which will become fertilised and produce offspring. The process of spawning typically involves females releasing ova (unfertilized eggs) into the water, often in large quantities, while males simultaneously or sequentially release spermatozoa (milt) to fertilise the eggs. Spawning grounds help understand the species distribution of a particular commerically important fish.

]]>Marine nursery areas are habitats that promote the survival of young commercially important fish species. Many of these creatures are important to humans in fisheries and seafood. These habitats are essential for the reproduction and understanding of the geographical species distribution. Take them away or degrade them, and the production of commercially harvested species will decline or cease altogether.

]]>The primary goal of the Irish Groundfish Survey is to develop estimates of juvenile abundance for important fish species. Measurements of the abundance of juvenile fish are a critical measure of the health of a stock, serving as an annual indication of recruitment (the number of newly spawned fish which enter the population each year) success or failure. Most importantly, they allow forecasting of future commercial abundance. In addition, the Irish Groundfish Survey provides data on the distribution and biology of commercial and non-commercial species of ecological interest, as well as hydrographic and environmental observations. When these data are combined with annual recruitment indices they can help identify the possible causes driving year-class success or failure, and allow us to see long-term changes in populations that may have been caused by fishing, pollution, or climate change. This spatial dataset comprises the haul station location from the trawl survey. The Irish Groundfish Survey feeds into the International Bottom Trawl Survey e.g. IBTS for international reporting.
