A new nicothoid copepod parasitic on mysids
from northwestern North America.
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.
Larkin's 1946 thesis had investigated the ecology of mysids
in northwestern Canada, and he eagerly leveraged this knowledge into practical applications.
The sympod on the antennules of adult males was characterized development of soft sensory setae (see both species, after attaining size 6.0 mm, the immature males mysids
, less than 5 mm in size lacked the setae.
The EPA is considering using mysids
in its Endocrine Disruptor Screening Program as a model invertebrate species to test for the toxic effects of chemicals, Meiller said.
The diet of Bairdiella chrysoura was dominated by mysids
, decapod shrimp, and fish, with slight differences between habitats.
His current hypothesis is that the once--thriving mysids
need some time to recover before their chief predators can return.
integer was estimated from length measurements of 250 mysids
selected randomly from a sample on each sampling date in 1973 and 2005.
piscicida and Vibrio spp., have been reported in association with aggregation and mortalities of penaeid shrimp zoeae and mysids
in culture conditions [4, 6, 33].
and daphnids, like many other arthropods, have a specific hormone regulation for growth and reproduction, namely the ecdysteroid system (54).
Behind the scenes, a scientist checks on some giant red mysids
(MY-sids)- -a kind of shrimp.
