Lipid Condition and Survival in Shrimp ( Pandalus borealis ) Larvae
Croups of shrimp (Pandalus boreal is) larvae were reared under dif ferent food concentrat ions and types to assess changes in condit ion and survival during development. As expected, rate of growth (wet weight) was highei for la rvae fed on 300 Ar temia naup l i i .L r (San Franc isco s t ra in : 0 .0528 mg 'd ' ; Canada s t ra in : 0 .0355 mg 'd ' ) compared w i th those reared a t 150 naup l ...
متن کاملEnvironmental factors affecting recruitment of northern shrimp Pandalus borealis in West Greenland waters
Survey estimates of northern shrimp Pandalus borealis biomass in West Greenland waters increased from about 178 000 t in 1998 to about 598 000 t in 2003. The increase in stock size was preceded by several consecutive years in which recruitment was substantially above average. Recruitment has been poor since then despite record high levels of female stock biomass. Rickertype stock-recruitment fu...
متن کاملAge and size at maturity: sex, environmental variability and developmental thresholds.
In most organisms, transitions between different life-history stages occur later and at smaller sizes as growth conditions deteriorate. Day and Rowe recently proposed that this pattern could be explained by the existence of developmental thresholds (minimum sizes or levels of condition below which transitions are unable to proceed). The developmental-threshold model predicts that the reaction n...
متن کاملFactors Related to the Age at Menarche in Iran: A Systematic Review and Meta-Analysis
Background Reduced age at menarche is an important health indicator for women and may be associated with complications such as an increased risk of asthma, breast cancer, ovarian cancer, type 2 diabetes. We aimed to examine the factors related to the age at menarche in Iran. Materials and Methods: In this systematic review and meta...
متن کاملAge, growth and length at first maturity of Otolithes ruber in the Northwestern part of the Persian Gulf, based on age estimation using otolith
Estimates of age, growth parameters, length-weight relationship and length and age at first maturity of the otolithes ruber are required for fishery management. We used counting annuli on the section of sagittal otoliths to age O.ruber from the Northwest Persian Gulf in south of Iran. Estimated ages ranged from 0 to 6 years, and maximum frequency of fishes was observed in age-group 1. The val...
