Unlike the more celebrated Atlantic salmon, whose scarcity and moodiness in taking a fly has resulted in elegant but rigid traditions, fishing for silvers here along Prince William Sound has a far more relaxed feel.

Firstly, the vast majority of the collected GPGP objects were made of PE and PP rigid plastics and bundled fishing nets and ropes.
There is no electrical organ in the notopterids, however; the rigid body of these fishes may be correlated with the long gas-filled swim bladder that extends into the tail end of the body.
A Stabilizing controller, fish-tail mechanism, rigid body dynamics, and kinematics are incorporated to enable the fish robot to move in three dimensional space.
The food was mostly stuff that not even a boarding school could get away with now: a sad-looking salad with a single cherry tomato in the center, a fish fillet as rigid as tree bark.
Look for fish that are still stiff and rigid and in 'rigor mortis' – this will indicate that the fish has been out of the water for no more than a day or so.
In the natural world, however, bodies are more likely to be flexible, like a fish's, rather than rigid, like a car's.
In Madagascar, rigid taboos govern when people can fish and what gear they can use.
