Dietary Cholesterol Requirements of Large Red Swamp Crayfish (Procambarus clarkii)

Aquaculture Nutrition, Volume 2023, Issue 1, 2023., 2023
To investigate the dietary cholesterol requirements of large red swamp crayfish (Procambarus clarkii), crayfish (initial body weight: 13.49 ± 0.22 g) were hand‐fed six diets containing 2.47 (C0), 4.27 (C1), 6.80 (C2), 8.77 (C3), 11.74 (C4), and 14.24 (C5) g/kg cholesterol.

Turbine Sound May Influence the Metamorphosis Behaviour of Estuarine Crab Megalopae

PLoS ONE, 2012
It is now widely accepted that a shift towards renewable energy production is needed in order to avoid further anthropogenically induced climate change. The ocean provides a largely untapped source of renewable energy. As a result, harvesting electrical power from the wind and tides has sparked immense government and commercial interest but with ...

Macrogenetics Approach Reveals Spatial Trends and Drivers of Mitochondrial Genetic Diversity at Different Biological Organization Levels in Tropical Western Atlantic Decapods. [PDF]

Ecol Evol
There is a knowledge gap concerning the genetic diversity distribution across marine invertebrates, and whether the latitudinal genetic diversity gradient results from congruent intraspecific trends. Our results indicate higher genetic diversity in lower latitudes is correlated to productivity and oxygen levels, but does not represent the accumulation ...

Impaired larval development at low salinities could limit the spread of the non-native crab Hemigrapsus takanoi in the Baltic Sea

Aquatic Biology, 2021
The Asian shore crab Hemigrapsus takanoi, native to the northwest Pacific Ocean, was recently discovered in Kiel Fjord (southwestern Baltic Sea). In laboratory experiments, we tested the salinity tolerance of H.

Leg disposition in the brachyuran megalopa when swimming [PDF]

Journal of the Marine Biological Association of the United Kingdom, 1954
SummaryMany brachyuran megalopae swim with the legs disposed in a curious manner. The chelipeds and first two pairs of walking legs are folded tightly beneath the body, while the two posterior pairs are wrapped over the dorsum, the third pair being stretched out anteriorly, the dactylus, according to its length, touching or being looped round the eye ...

The larval development of Pilumnoides hassleri (Decapoda: Brachyura: Pilumnoididae) reared in the laboratory, with a review of pilumnoidid systematics using larval characters

Scientia Marina, 2010
The genus Pilumnoides is an interesting taxon because its systematic position, based on adult characters, remains unclear. These xanthoid crabs have been related to the Carpiliidae, Goneplacidae and Eriphioidea. P. hassleri A.

Integrative transcriptomic and metabolomic analysis reveals the effects of a sudden drop in salinity on osmoregulation, metabolism, anti-oxidation, and immunity in Eriocheir sinensis megalopa and juvenile stages

Aquaculture Reports, 2023
Eriocheir sinensis has a special habit of migrating from marine to freshwater during its larval developmental stage. Salinity is an important environmental factor affecting the survival rate and growth performance of its larvae.

Induction of settlement in crab megalopae by ambient underwater reef sound [PDF]

Behavioral Ecology, 2009
The larvae of a number of crab species have been found to orientate and swim toward ambient underwater sound emanating from coastal settlement habitats. This current study examined whether ambient underwater sound also has the potential to trigger settlement responses in crab larvae.
