Hammerhead sharks are represented by four species in India's marine fishery – Sphyrna lewini, mokarran, zygaena and Eusphyra blochii. This paper describes the hammerhead shark India during 2007–2018 summarizes observations on biology of S. lewini exploited along Indian coast. caught trawl nets, gillnets, seines line gear, mostly as bycatch. Annual average landing 2007–18 was 639 t, with a low 2...

The aim of this study was to purify and identify peptides with antioxidant properties from protein hydrolysate of scalloped hammerhead (Sphyrna lewini) cartilage. Cartilaginous proteins of the scalloped hammerhead were extracted by guanidine hydrochloride, and three antioxidant peptides, named enzymolysis peptide of scalloped hammerhead cartilage A (SCPE-A), SCPE-B and SCPE-C, were subsequently...

Metabolic and activity rates determined from free-ranging juvenile scalloped hammerhead shark pups (Sphyrna lewini) in Kāne’ohe Bay, Ō’ahu, HI, were used to develop a simplified energy budget for this population. Five shark pups were tracked using a specially designed acoustic tail beat transmitter. Previous laboratory experiments determined that tail beat frequency (TBF) and water temperature ...
