Variability in swimming behavior among broods of blue crab (Callinectes sapidus) zoeae

Journal of Experimental Marine Biology and Ecology, 2019
Abstract Blue crabs (Callinectes sapidus) support economically important fisheries across the eastern United States, which have exhibited historical variability in recruitment. Blue crab zoeae develop in surface waters over the continental shelf, where they need to constantly swim upward in order to stay within surface currents to successfully ...

Crushing and Cutting: Shape Variation and Morphological Integration Between the Claws of Two Swimming Crab Species (Brachyura: Portunidae)

Acta Zoologica, EarlyView.
ABSTRACT This study investigated shape variations and morphological integration between the components of crusher and cutter claws in two species of swimming crabs, Callinectes danae and Callinectes ornatus. The propodi and dactyli of the claws were analysed in males and females of both species, using geometric morphometric techniques to identify ...

Geometric Morphometrics Reveal Body Shape Variation in Freshwater Shrimps of the Genus Macrobrachium Lacking a Mandibular Palp (Formerly Pseudopalaemon Sollaud, 1911) (Decapoda: Palaemonidae)

Acta Zoologica, EarlyView.
ABSTRACT Shape variation in the cephalothorax of Macrobrachium species without mandibular palp using geometric morphometrics was used as a tool to support species differentiation and propose new diagnostic characters for taxonomic identification.

Evaluation of toxicity effect of Datura innoxia root extract to Clarias gariepinus fingerlings [PDF]

, 2003
Clarias gariepinus fingerlings were exposed 96 hours under laboratory conditions using static bioassays with continuous aeration to determine acute toxicity of Datura innoxia root extract. The LC sub(50) of the exposed fingerlings was 128.83 mg/L.

Male‐territory‐visiting polygamy in the sand‐dwelling goby Fusigobius inframaculatus (Gobiidae) inhabiting reef caves

Journal of Fish Biology, EarlyView.
Abstract We conducted an observational field survey of the innerspotted sandgoby Fusigobius inframaculatus on reefs of Kuchierabu‐jima Island, southern Japan, to investigate its mating system. Individuals of the goby maintained home ranges on sandy bottoms within rocky caves or beneath overhangs that served as shelters. Of 34 identified individuals, 32%

IDENTIFICATION AND PREVALENCE OF ECTOPARASITES IN BLUE SWIMMING CRAB (Portunus pelagicus Linnaeus, 1758) ON THE NORTH COAST OF JAVA

Jurnal Teknologi Perikanan dan Kelautan
Besides overfishing, other factors that influence the decline in blue swimming crab (Portunus pelagicus) production are diseases caused by parasites. Poor environmental conditions could trigger parasite infestation on their host.
