Reproductive dynamics of a swimming crab (Monomia haanii) in the world’s crab basket
Fisheries Research, 2021Abstract Red swimming crab Monomia haanii is an important export fishery in southern China. M. haanii is mainly sold as lump crabmeat, generating an annual trade of tens of millions of US dollars over the last decade. For such a commercially important crab species, little attention has been paid to the sustainable use of the stocks and there remains ...

Swimming of the pea crab (Pinnotheres pisum)
Animal Biology, 2014Aquatic organisms have to deal with different hydrodynamic regimes, depending on their size and speed during locomotion. The pea crab swims by beating the third and fourth pereiopod on opposite sides as pairs. Using particle tracking velocimetry and high-speed video recording, we quantify the kinematics and vortices in the wake of the pea crab.

Motoneuronal commands during swimming behaviour in the shore crab
Brain Research, 1990Neurograms of proximal leg motor nerves were obtained during swimming in the shore crab. Whereas excitor motoneurones fire in bursts, the common inhibitor motoneurone discharges tonically with simultaneous spikes in all the motor nerves. The average firing frequency of the common inhibitor increases as the period of the swimming cycle decreases ...

Arthropod Structure & Development, 2020
Most brachyuran crabs use their pereiopods as walking legs, but there are also a number of species, in which the last (5th) pair of pereiopods (P5) are specialized to permit a unique mode of swimming. One of these P5-swimming crabs is Liocarcinus depurator, commonly found on European shores.

Accumulation, detoxification, and toxicity of dibutyl phthalate in the swimming crab
Chemosphere, 2022Dibutyl phthalate (DBP) is one of the most commonly used and toxic phthalate esters and has a variety of harmful effects on aquatic animals. However, there is still a lack of knowledge on the accumulation, detoxification, and toxicity of DBP in aquatic animals.

Polarised light-sensitive interneurones in a swimming crab
Nature, 1976THIS report shows that there are polarisation-sensitive inter-neurones in the crab visual system, contrary to recent speculations1. It also shows that polarised light information in crabs is elaborately processed.

Ribosomal DNA Intergenic Spacer of the Swimming Crab, Charybdis japonica
Journal of Molecular Evolution, 1999We have determined the full sequence of the ribosomal DNA intergenic spacer (IGS) of the swimming crab, Charybdis japonica, by long PCR for the first time in crustacean decapods. The IGS is 5376 bp long and contains two nonrepetitive regions separated by one long repetitive region, which is composed mainly of four subrepeats (subrepeats I, II, III, and

Swimming in the dromiid crab (Homola barbata)
Animal Behaviour, 1970Abstract Swimming was observed in specimens of the dromiid crab Homola barbota collected at Naples, and the swimming technique was studied by the analysis of cine film. The first, second and third walking legs beat in the frontal plane of the crab. The duration of the backward propulsive stroke is the same as that of the forward recovery stroke.

Bait Improvement For Swimming Crab Trap Fisheries
2011One of the most commonly cited problems regarding age determination in crustaceans is the absence of any calcified structures containing growth rings. The question addressed by this study is: do the zygocardic, prepyloric and pyloric ossicles of the gastric mill of decapod crustaceans contain any record of growth?

Dietary lysine requirement of juvenile swimming crab, Portunus trituberculatus
Aquaculture, 2015Abstract An 8-week feeding trial was conducted to determine the optimal dietary lysine requirement for juvenile swimming crab reared in cement pools. Six iso-nitrogenous and iso-lipidic experimental diets (49.5% crude protein and 7.0% crude lipid) were formulated to contain graded levels of lysine, which were 1.58%, 1.89%, 2.15%, 2.41%, 2.67% and 2 ...
