NOAA Fisheries conducts research on shark habitats, migratory patterns, and population change in order to understand how to best protect and maintain a stable shark population The Dragon Behind the Glass: A True Story of Power, Obsession, and the World's Most Coveted Fish Northern Red Snapper — A red-tinted fish that is very popular for commercial fishing Sharks of New England download epub The head, tail, fins and claspers (organs used to transfer sperm from the male to the female shark during mating) are now held in the fish collection of the Australian Museum.

As well as target fishing, they also form a huge 'by-catch' in other fisheries. Additionally, there is a large recreational fishery and in many cases, those sharks caught are killed, weighed and ‘scored’, and then wastefully dumped at sea. Coastal development is reducing shark ‘nursery areas’, and environmental threats such as pollution, and bio-amplification of organ compounds and heavy metals, directly or indirectly impact on sharks just as they do on all marine species , source: Fishwatchers Guide to West Atlantic Coral Reefs: With Coral Identification Plate, Waterproof edition

Sharks reach maturity at the age of 13 – 15. The fertility in sharks ranges from 2 to 100 young per reproductive cycle. Mating is an uncommon phenomenon in these species. Most sharks are ovoviviparous in that the eggs are hatched in the oviduct in the mother’s body. The period of gestation lasts for about 18 – 24 months. Some the shark species are highly sociable. These are mainly found in the Gulf of California In Pursuit of Giants: One read for free Elsewhere the species may reach a lager adult size (to 195 cm in the eastern North Pacific) and have a larger size of maturity.

Some of these fishes get very large, such as the Tinfoil Barb and the Bala Shark Chance Is the Providence of Adventurers Anglers and spearfishers catch around 140 tons of leopard sharks per year in California. There's also a small commercial fishery in California that brings in an additional 30 tons per year.
