Feeding ecology of the American crab Rhithropanopeus harrisii (Crustacea, Decapoda) in the coastal waters of the Baltic Sea

Abstract: Cyanobacteria, otherwise known as blue-green algae, are oxygenic, photosynthetic prokaryotes. They occur naturally in many fresh, marine and brackish waters worldwide and play an important role in global carbon and nitrogen cycles. In their long history, cyanobacteria have developed structures and mechanisms that enable them to survive and proliferate under different environmental conditions. In the Baltic Sea, the mass development of cyanobacteria is compounded by a high level of eutrophication. The dominant … Show more

“…Dietary proportions are expressed as the median and 95 % Bayesian credible intervals for each of the two water exchange regimes with lagoons entered as categorical covariates. Selection of possible prey items used in the mixing model, for the non-native species was based on: stomach content analysis performed in a parallel study for the non-native shrimp P. macrodactylus and the native shrimp P. varians (Moghaddam 2012), the non-native fishes Fundulus heteroclitus heteroclitus Linnaeus and Gambusia affinis Baird & Girard (Deamer-John 2012), and the literature for the non-native corixid Trichocorixa verticalis Fieber and the non-native crab Rhithropanopeus harrisii Gould (Kelts 1979;Hegele-Drywa and Normant 2009;Simonis 2012). Important prey items for other fish species were selected using Fishbase (2012).…”

“…In its invasive range mud crabs occur from exposed hard bottoms to sheltered soft bottoms that are either unvegetated or vegetated 18 . Within these habitats the mud crab has a very broad diet potentially including macroalgae and benthic invertebrates 21 , either sessile and mobile species 22 , and the diet composition is largely driven by prey availability 23 . Currently, the Baltic Sea provides R .…”

“…In addition, estuarine intertidal crabs feeding in different parts of an estuary could face not only distinct tidal patterns but also different predation pressures and food resources. Therefore, variations in feeding activity and diet are expected (Ryer ; Heguele‐Drywa & Normant ). Feeding of intertidal crabs, active at low tide, or moving in shallow clear coastal waters, can be directly seen in natural conditions (Wolfrath ; Cannicci et al .…”
