Behavioural and physiological studies of aggression in swimming crabs

Journal of Experimental Marine Biology and Ecology, 1995
Abstract This article reviews three studies of agonistic interactions in pairs of swimming crabs (Liocarcinus depurator and Necora puber) in which behavioural and physiological approaches were combined. In both species most fights were won by the larger crab.

Swimming in Spider Crabs of the Genus Macropodia

Nature, 1960
THE only adult Brachyura which have previously been recorded swimming are the Portunidae, which do so by rapid paddling of the last pair of peraeopods. These are adapted for swimming by having the distal segments flattened, with the edges densely fringed with hairs.

Rapid immunochromatographic test strip to detect swimming crab Portunus trituberculatus reovirus

Diseases of Aquatic Organisms, 2015
Swimming crab reovirus (SCRV) is the causative agent of a serious disease with high mortality in cultured Portunus trituberculatus. A rapid immunochromatographic assay (ICA) was developed in a competitive assay format and optimized for the detection of SCRV.

Energy response of swimming crab Portunus trituberculatus to thermal variation: Implication for crab transport method

Aquaculture, 2015
Abstract Temperature variation and air exposure are two predominant abiotic stressors during the transport and storage of Portunus trituberculatus . To understand the effects of these factors on P. trituberculatus , we examined the hemolymph (hemocyanin, glucose and lactate level) and muscle indicators (glycogen content, metabolic enzymes activity ...

Dietary protein requirements of the juvenile swimming crab, Portunus trituberculatus

Aquaculture, 2013
Abstract An 8-week feeding trial was conducted to determine the optimal dietary protein requirements for juvenile swimming crabs ( Portunus trituberculatus ) reared in cement pools. Six iso-energetic and iso-lipidic experimental diets were formulated to contain graded levels of protein, and these dietary protein levels were 31.6, 36.5, 41.7, 45.6, 50.

Surface Swarms of Swimming Crab Megalopae At Curaçao (Decapoda, Brachyura)

Crustaceana, 1982
[Vor der Kuste von Curacao traten im September 1970 und Oktober 1980 riesige, monospezifische Schwarme von Megalopa-Larven auf. Die Larven liesen sich als zur Unter-familie Portuninae gehorig identifizieren. Sie unterscheiden sich aber von allen bisher beschriebenen Megalopa-Larven und konnen deshalb nicht genauer bestimmt werden. Mogliche Mechanismen,
