We studied age, growth, and maturity of the oceanic whitetip shark Carcharhinus longimanus in the North Pacific, and the reproduction in the North and South Pacific, captured with tuna longline from Nov. 1967 to Oct. 1995. Vertebral rings were examined from 111 males (precaudal length: 54-172 cm) and 114 females (precaudal length: 50-195 cm). Minimum and maximum numbers of translucent rings were 0 and 11. Marginal increment analysis suggested annualus deposition occurs during spring. A growth…

Estimates of life history parameters of the oceanic whitetip shark, Carcharhinus longimanus, in the Western North Pacific Ocean
TLDR
The age, growth and reproduction of the oceanic whitetip shark, Carcharhinus longimanus, in the western North Pacific Ocean were estimated based on 188 specimens collected before the prohibition of retaining on board for commercial use by the Western and Central Pacific Fisheries Commission at the Nanfanao fish market in north-eastern Taiwan.
Age, growth and maturity of oceanic whitetip shark (Carcharhinus longimanus) from Papua New Guinea
TLDR
Oceanic whitetip sharks (Carcharhinus longimanus) in the Western Central Pacific have been overfished and require improved assessment and management to enable planning of recovery actions, highlighting increased vulnerability to fishing pressure in this region.
NOTES ON THE REPRODUCTION OF THE OCEANIC WHITETIP SHARK, CARCHARHINUS LONGIMANUS, IN THE SOUTHWESTERN EQUATORIAL ATLANTIC OCEAN
TLDR
Preliminary data suggest that size at first maturity is occurring from 160 to 196cm in males and from 181 to 203cm in females in this population of oceanic whitetip sharks for the southwestern equatorial region of the Atlantic Ocean.
AGE AND GROWTH OF THE BLUE SHARK, PRIONACE GLAUCA, IN THE NORTH ATLANTIC OCEAN
TLDR
The blue shark grows faster and has a shorter life span than previously reported in these waters and growth rates from tag-recaptures agreed with those derived from vertebral annuli for smaller sharks but appeared overestimated for larger sharks.
The Biology and Ecology of the Oceanic Whitetip Shark, Carcharhinus longimanus
TLDR
On the basis of its life-history characteristics, this species is presently considered by the World Conservation Union to be vulnerable to, but not currently threatened by, pelagic sheries.
Reproductive aspects of the oceanic whitetip shark, Carcharhinus longimanus (Elasmobranchii: Carcharhinidae), in the equatorial and southwestern Atlantic Ocean
TLDR
The reproductive cycle of the oceanic whitetip shark is most likely biennial, with parturition occurring once every two years.
Inferring Life History Characteristics of the Oceanic Whitetip Shark Carcharhinus longimanus From Vertebral Bomb Radiocarbon
TLDR
Preliminary data are preliminary in nature but provide some evidence that Δ14C patterns in vertebrae can serve as a multi-purpose tool for life history studies of oceanic sharks.
Reproductive biology of the blue shark (Prionace glauca) in the western North Pacific Ocean
TLDR
The results showed that the productivity of North Pacific blue sharks is higher than previously thought, based on larger fecundity and a shorter reproductive cycle, which will improve future stock assessments and provide management advice.
Validated age and growth of the dusky shark, Carcharhinus obscurus, from Western Australian waters
TLDR
Growth-rate estimates based on vertebral ageing for animals up to 5 years of age are similar to those from tag–recapture studies on the same population, indicating that age and growth are similar among these populations.
Age and growth of the daggernose shark, Isogomphodon oxyrhynchus, from northern Brazil
Age and growth of the daggernose shark, Isogomphodon oxyrhynchus, from northern Brazil were deter- mined from 105 vertebral sections stained with alizarin red-S representing 46 males, 52 females and
