Cartographic characterization of the littoral camps of dunes

This work ls based on a atudy about tbe Dunes Camp of Maspalomas (fígure 1), in Gran Canaria Island (Spaln). Their sedimentary processes are detached and represented separately in order to delimit the diferent sedimentary and eolian sub-unit to get an "spectral" analysls. The developed analytic serie permit us to construct a sequence of thematic maps Later, the cartographlc puzzle is integrated, once the pbyslcal varieties of tbe sedimentary dynamycs that intervene in lbe terrltory 1s well konwn and clearly understood. Tbe cartography of integration or the general vision about the processes of both transport and sedimentary deposits contains yet enough information, inside a physical perspective ( based on the dune biotope ), to decide in relatlon to the arrangement, planning and management of the territory.

Obtención en cautividad de puestas naturales del pez de limon(Seriola dumerili), en la isla de Gran Canaria (España).

[EN]In the present study, natural spawning of a broodstock group of greater amberjack (Seriola dumerili) is described with regards to: date, number of spawns, and total number of eggs produced per spawn. Fish werecaught in 2011 in the Canary Islands, Gran Canaria (Canary Islands, Spain), and kept in captivity. At the end of May 2014, the broodstock group was formed by two females with a weight 9.81±1.08 kg, size 90.0±2.82cm, with oovocites > 800μ, and five males 9.46±2.04 kg, 86.75±5.43 cm, all fluent with sperm. Between the 1stof June and 18thof October 2014, a total of 25.60 million eggs were obtained in 23 spawns.
