Newly hatched cuttlefish attack particular prey, such as mysid shrimp
, with defined actions soon after hatching; therefore, hunting behavior via tentacular strike is considered innate (Wells, 1958, 1962).
Although we saw large numbers of small (<20 mm FL) bay anchovy in the shore zone during the day, larger individuals (mean: ~60 mm FL) were more dense in the shore zone at night, possibly as a response to both increased foraging opportunity on mysid shrimp
, a staple of their diet (Hartman et al., 2004), and because of reduced avian predation.
, which are 1 inch long or smaller, hang in the water anywhere from the surface to the seafloor - in concentrations 2 to 20 feet thick.
Louisiana sweet crude was more toxic to mysid shrimp
than the eight dispersants, when tested alone.
The diet of Bairdiella chrysoura showed the least amount of variation across habitat, with mysid shrimp
comprising nearly half the diet in both habitats.
devour microscopic animals, which many young fish in the Great Lakes also eat.
EDSTAC (1) and the consequent EDSP proposal (2) both recommend the use of crustacean life-cycle assays for higher tier testing, with daphnids or mysid shrimps
as the suggested test organisms.
The principal prey of summer flounder <60 mm TL were mysid shrimp
and copepods, whereas sand shrimp (Crangon septemspinosa), amphipods, and fish were the dominant prey of larger conspecifics.
That's because the coast's insistence on overcast skies this year deprived the nearshore ecosystem of sunlight, the necessary ingredient in kelp beds, upon which mysid shrimp
are known to feed.
The data points in the center of this graph indicate those prey that were more frequently found in the stomachs of Atlantic croaker than in the stomachs of the other 2 species: mysid shrimp
, various unidentified crustacean parts, and gammaridean amphipods.
She went diving to investigate and found large swarms of mysid shrimp
Despite the diversity of prey, nearly half of the diet comprised mysid shrimp
(Neomysis spp.) and bay anchovy (Anchoa mitchilli).
