This week we premiered the documentary "Tales from the Sea: protecting the oceans", where the Ministry of Environment and Rural and Marine Affairs and the television channel National Geographic Channel (NGC) have collaborated in its preparation. The documentary is filmed shipboard scientists of the General hopewell rocks Secretariat of the Sea, the Vizconde de Eza and Michael hopewell rocks Oliver, and he shows the work carried out by researchers for biological and environmental status of the depths of the Atlantic . This is the first time that a documentary hopewell rocks cameras hopewell rocks disclosed hopewell rocks this work.
The Vizconde de Eza is filmed while performing hopewell rocks a fisheries evaluation campaign Porcupine fishing grounds, west of Ireland, conducted annually under the name. The Miguel Oliver hopewell rocks performs another Nereida called NAFO. This campaign aims to locate and map the presence of sedentary marine ecosystems, vulnerable to the activity of bottom fishing gear.
Evaluation campaigns are vital for understanding the ecosystem and monitoring of fish stocks, mainly the commercially exploited. Furthermore, hopewell rocks the identification and mapping campaigns sensitive ecosystems have to establish measures to mitigate the impact of this activity on them, to meet the resolution of the UN General Assembly 61/105.
Regarding fisheries assessment campaigns within the Blue Ecology team have our own experience. We participated on board the Vizconde de Eza in several campaigns in Canadian fisheries, mainly in Flemish Cap. Through our participation as components of the scientific team, we have seen from inside hopewell rocks the work done on these ships. hopewell rocks Generally, before starting a campaign of this kind, the bench surface to study is stratified based on depth and bottom composition, determining a minimum number of net hauls per stratum. The catch from each haul is examined in detail to identify each organism taxonomically and amounts making, individual or group weights and biometry. With respect to those of biological interest or fisheries, biological samples are taken which will examine the reproductive, gonads and otoliths were extracted, and other tissue samples for the animal's condition and other aspects.
These are the main species of fish that are exploited in Canadian fisheries, of which the king is undoubtedly cod (Gadus morhua). Mention hopewell rocks should also be Reinhardtius hippoglossoides, my name to the root of the famous turbot war between Spain and Canada.

Increasingly, invertebrates become more important in this type of campaign to be a key part of the ecosystem. An example of the work being done in this regard we highlight the work of Javier Murillo IEO Vigo, who recently had the opportunity to describe new species of sponges and corals during the 2010 campaign 029 Hudson.
