![]() They were responsible for the highest abundance peaks of shrimps occurring in the pools. elegans, generally entered the pools in spring and formed a high proportion of the population between April and August. New-recruits of the most abundant species, P. Lower mean sizes of all shrimp were registered in the beginning of spring, most often in April or May, and gradually increased until winter. Rare and exotic species were present mostly in spring-summer. elegans was present in all pools, throughout most of the year. Shrimp populations varied seasonally and among pools, with peak numbers in spring and summer. The shrimp population comprised 8 species: the European rock shrimp, Palaemon elegans, the common prawn, Palaemon serratus, the Atlantic ditch shrimp, Palaemon varians, the Baltic prawn, Palaemon adspersus, the Oriental shrimp, Palaemon macrodactylus and the relatively rare shrimps Eualus sollaudi, Eualus drachi and Caridion gordoni. Species diversity was much higher than that found in previous studies, in other parts of the world. Shrimps were sampled monthly from six tidal pools for one year, in the west Portuguese coast. ![]() This study aims to investigate the habitat use and dynamics of the shrimp species that occur in tidal pools of a North-eastern Atlantic coast, the Portuguese coast, in particular species composition, abundance, seasonality and size structure. Rocky shores are among the most-intensively studied ecosystems, however, tidal pools remain relatively understudied.
