Abstract
XX Iberian Symposium on Marine Biology Studies (SIEBM XX) , Braga, Portugal, 9 Sep - 12 Sep, 2019.
Highlights
To test the hypothesis that the prevalence of this pea crab in subtidal mussels depends on the degree of exposure/shallowness of their habitats and of the coexistence of hosts of all crab demographic categories in a reduced area, in this study we assess the prevalence and demographic structure of A. monodi in the subtidal mussels attached to the submerged chains of the navigational buoys of the Port Authority located along the navigable channel of the bay of Cadiz
Mussels were collected by hand from the submerged chains of five of the buoys used as lateral marks of the navigable channel of the Bay of Cadiz
Results of χ2 tests indicated that these inter-buoy differences in the annual pea crab prevalence were statistically significant (p < 0.01) among the three inner buoys (B12, B10 and B8) and the two outer buoys (B4 and buoys number 2 (B2)), as well as among the two inner buoys (B12, B10) and the intermediate buoy (B8; Figure 1)
Summary
As many other Pinnotherid crabs, the African pea crab Afropinnotheres monodi live in association with the mantle cavity of different bivalve species. This pea crab causes a significant reduction of the condition index of the mussel Mytilus galloprovincialis. To test the hypothesis that the prevalence of this pea crab in subtidal mussels depends on the degree of exposure/shallowness of their habitats and of the coexistence of hosts of all crab demographic categories in a reduced area, in this study we assess the prevalence and demographic structure of A. monodi in the subtidal mussels attached to the submerged chains of the navigational buoys (lateral marks) of the Port Authority located along the navigable channel of the bay of Cadiz
