This study showed that ferrite magnets induced behavioral responses in all the tested elasmobranchs
and that permanent magnets may be able to reduce elasmobranch
Basking sharks, like many other elasmobranchs
, have a slow growth rate and low fecundity (Holden, 1973).
In studies of elasmobranchs
by OTC-injection, sharks are measured, injected with OTC, tagged, and released.
It is important to recognize, however, that elasmobranchs
are not only targeted by certain fisheries, but also comprise a substantial component of the bycatch of commercial fisheries, such as those employing trawl nets, gillnets, and longlines (Stevens et al.
Although pelagic sharks are affected by fishing, they remain among the least studied elasmobranchs
because of their highly migratory nature and because the lack of information on these species poses particular difficulties for their management and conservation (Pikitch et al.
Mongolepis--a new Lower Silurian genus of elasmobranchs
Demersal fish species in Puget Sound are consumed by elasmobranchs
, such as Spiny Dogfish (Squalus acanthias) and Bluntnose Sixgill Shark (Hexanchus griseus), and marine mammals, such as the harbor seal (Phoca vitulina; Bromaghin et al.
Etymology: Based on the type locality, Ningaloo, the location of an important marine park rich in species of elasmobranchs
2000), creating prime nursery conditions for a variety of vertebrate and invertebrate taxa, including: crabs (Sanchez-Ortiz and Gomez-Gutierrez 1992), shrimps (Flores-Castanon 1980), bony fishes (Castro-Barrera 1975; Gutierrez-Sanchez 1997), elasmobranchs
(Guardado-France 1976; Villavicencio Garayzar 1995; Bizzarro et al.
In 1946, the Pajaro Valley Rod and Gun Club (PVRGC) initialed a late spring-early summer angling derby for elasmobranchs
in Elkhorn Slough.
An additional problem with the use of chemical marking techniques, such as with OTC, is that growth may be inhibited (Pfizer, (5) 1975; Monaghan, 1993); however, other researchers that have worked with elasmobranchs
have shown OTC to have little adverse effects on growth (Tanaka  for the Japanese Wobbegong [Orectolobus japonicus] and Gelsleichter et al.
