Aspects of the fishery biology of the lady crab (Ovalipes ocellatus) in New York waters, 8 p.
The effect of reduced salinity on osmoregulation and oxygen consumption in the lady crab, Ovalipes ocellatus (Herbst).
During a 1991-94 monthly otter trawl survey in the Hudson-Raritan Estuary between New York and New Jersey, blue and lady crabs were collected in warmer months and Atlantic rock crabs in colder months.
Trophic overlap was lowest between lady crabs and Atlantic rock crabs, mainly because of frequent consumption of the dwarf surfclam (Mulinia lateralis) by the former and the blue mussel (Mytilus edulis) by the latter.
In lady crabs from the New York coast, nearly all males are mature at [greater than or equal to] 6 cm, and females at about 5 cm (Briggs and Grahn (3)).
For graphic representation of ontogenetic differences in diet, blue and rock crabs were grouped for convenience into 20-mm CW classes, and lady crabs were grouped in 10-mm CW classes because of their smaller size range.
Abundances of female blue and lady crabs in the study area were greater than those of the males.
The maximum relative abundance of blue and lady crabs occurred during the warm months each year, whereas rock crabs were abundant only in the cold months (Fig.
Very few molting or postmolt blue or lady crabs were caught.
Lady crabs were widely distributed and were caught throughout the study area, including the outer strata close to the ocean.
The diets of lady crabs and rock crabs were significantly different in two taxa: M.
Lady crabs of both sexes had the narrowest temporal niches (3.
The spatial niche breadths of lady crabs were largest (7.
