Description: 

Deep-se crustacean reproduction (CRUSREP)
The ocean covers more than two-thirds of our planet’s surface and occupies a vast three-dimensional volume, much of which is still unexplored, in particularly the deep sea. It is rich in resources and provides us with food. However, 90 percent of the global fish population is maximally exploited or has already been overfished.
Despite high abundance and biomass levels, the species life cycle and reproduction of decapods dwelling below 200 m is largely unknown. Deep-sea decapod species are or could be potential food resources or have an important ecological role as key components of the marine food web. Even in species highly exploited in the North Western Mediterranean sea as the shrimp Aristeus antennatus the knowledge of its life cycle is still incomplete. Accurate information on reproduction is mandatory to develop adequate fishing management plans.
The present offer want to fulfil this gap. The student will study the reproduction of deep-sea decapods present in our collection of trawling or plankton surveys. The tasks will consists in 1) identifying larvae and adult decapod crustaceans morphologically and/or genetically; 2) Describing secondary sexual characters under binocular and/or using scanning electronic microscope; 3) studying the ovarian maturation cycle by optical and/or transmission electron microscope.
