For FISH, multiple eggs were combined per preparation.
This finding suggests that our strategy to use a backcross design and test fish multiple times improved our ability to detect QTL.
We tested fish multiple times in two assays that test different aspects of schooling tendency: 1) the model school assay, which presents fish with a school of eight model sticklebacks; and 2) the choice assay, in which fish are given a choice between the model school and a stationary artificial plant.
In fish, multiple adaptive mechanisms can mediate survival at low temperatures, such as the synthesis of antifreeze proteins in Antarctic fish, endothermy in salmon sharks, the presence of a heater organ in swordfish and the enhancement of oxidative capacity in the striped bass and crucian carp (for a review, see Hochachka and Somero, 2002).
Wound repair events and TUNEL-positive cells for each treatment were counted in fields derived from multiple fish, and from multiple locations on the embryos.
I was attracted to the wood-carved little fish with multiple hooks dangling from them.
Exceptional Value and other special-protection waters typically have Class A or B wild trout status, too, which connotes a high density of fish in multiple year classes, and ensures a waterway the strictest environmental safeguards.
He'll travel to local fish markets multiple times a week to seek out fresh bonito from the Tsukiji fish market in Japan or local abalone and sea urchin from Santa Barbara. .
The genomes of teleost fish contain multiple copies of many genes compared to mammals.
On the other hand, archival tags provide the capacity to track fish over multiple years [5], [10], which can reveal subtle changes and ontogenety in movement patterns.
In any case these findings raise the interesting question of why fish possess multiple perforin paralogs.
