Metabolic rates scale isometrically in larval fishes

We estimated the rate of oxygen consumption of larval Atlantic mackerel Scomber scombrus at 3 temperatures (13, 16, 19 "C) while controlling rigorously for methodological biases. Routine metabolic rates (p1 O2 h-' ind.-l) increase with body weight (W, in mg) and temperature (T, in "C) as: RMR = 2.168 -W1 OoO e0.058 (rZ = 0.96). Thus metabolic rates scale isometrically with respect to body weigh...

Life-history correlates of maximum population growth rates in marine fishes.

Theory predicts that populations of animals with late maturity, low fecundity, large body size and low body growth rates will have low potential rates of population increase at low abundance. If this is true, then these traits may be used to predict the intrinsic rate of increase for species or populations, as well as extinction risks. We used life-history and population data for 63 stocks of c...

Visual pigments in the early life stages of Pacific northwest marine fishes.

Microspectrophotometry was used to measure the visual pigments in the rods and cones of 22 species of marine fish larvae netted from the surface waters off Friday Harbor Laboratories, Washington, USA. 13 species had rods, 12 of which contained visual pigments with a wavelength of maximum absorbance near 500 nm, while one, the sand lance (Ammodytes hexapterus), had its absorbance maximum at 482 ...

securitization of mortality risks in life annuities

insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...

Alterations in antioxidant defence in the early life stages of silver carp, Hypophthalmichthys molitrix

Fish larvae experience major cellular and biochemical changes during their early life stages.The aim of the present study was to evaluate alterations in the antioxidant status and values oflipid peroxidation and vitamin C content during the different life developmental stages ofHypophthalmichthys molitrix. Eggs and larvae were sampled at fertilization, organogenesis,eyed egg, hatch, active feed...
