REPRODUCTIVE BIOLOGY OF RIVER SWIMMING CRAB VARUNA LITTERATA

open access: yesIRAQI JOURNAL OF AGRICULTURAL SCIENCES
This study aims to obtain information on the reproductive biology of these species, especially on sex ratio, fecundity, ovarian development, and breeding season. The study was conducted from August 2022 to July 2023 on every full moon with the highest tide in the estuary of Bengawan Solo River, East Java, Indonesia.

Will Climate Change Alter the Swimming Behavior of Larval Stone Crabs?: A Guided-Inquiry Lesson

open access: yesCurrent: The Journal of Marine Education
The ocean has absorbed ~one third of the excess atmospheric carbon dioxide (CO2) released since the Industrial Revolution. When the ocean absorbs excess CO2, a series of chemical reactions occur that result in a reduction in seawater pH, a process called

Ghost fishing efficiency in swimming crab (Portunus trituberculatus) pot fishery

open access: yesMarine Pollution Bulletin
Abandoned, lost, or otherwise discarded fishing gear (ALDFG) is a global challenge that negatively affects marine environment through plastic pollution and continued capture of marine animals, so-called "ghost fishing". In different pot fisheries, ghost fishing related to ALDFG is of concern, including pot fishery targeting swimming crab (Portunus ...

Accumulation, detoxification, and toxicity of dibutyl phthalate in the swimming crab

Chemosphere, 2022
Dibutyl 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.

Motoneuronal commands during swimming behaviour in the shore crab

Brain Research, 1990
Neurograms 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 ...

Reproductive dynamics of a swimming crab (Monomia haanii) in the world’s crab basket

Fisheries Research, 2021
Abstract 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, 2014
Aquatic 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.
