Description
The specific objectives of the campaign are: 1-To determine the abundance and spatial horizontal distribution of eggs and larvae of bluefin tuna in the Balearic Sea during the peak of spawning lay of the species in the area. 2-To determine the abundance and horizontal spatial distribution of potential predators of ABFT eggs, especially Pelagia noctiluca, and predators and potential preys of bluefin tuna larvae present in the surface layers above the thermocline, where the eggs and larvae of ABFT are distributed. 3-To characterize the hydrological scenario in the study period and area. 4- To determine the vertical distribution of eggs, larvae and postlarvae of bluefin tuna and Pelagia noctiluca along the daily cycle 5- To determine the daily mortality rates of larvae of ABFT in their different stages of development in the different environmental conditions prevailing in the study area 6- To get samples to study the trophic ecology of pre-juvenile and larval stages of bluefin tuna.
