The Rearing of Lobster Larvae at Flodevigen

Behavior Constrains the Dispersal of Long-Lived Spiny Lobster Larvae

Behavior such as ontogenetic vertical migration (OVM) limits the transport of marine larvae with short pelagic larval durations (PLDs), but its effect on the supposed long-distance dispersal of larvae with long PLDs is unknown. We conducted laboratory tests of ontogenetic change in larval ph ototaxis and examin ed size-specific patterns of larval distribution in the plankton to characterize OVM...

How do spiny lobster post-larvae find the coast?

The larvae or phyllosomes of many species of spiny lobsters (Palinuridae) are known to complete their development in offshore oceanic waters. Phyllosomes metamorphose to non-feeding, nektonic post-larvae or pueruli, which move into shallow coastal waters where they settle to become benthic dwelling juveniles. There is growing evidence that the movement of pueruli is directed toward the coast ra...

Fatty acid composition of zooplankton and its transfer to common carp (Cyprinus carpio) larvae at the first week of larval rearing

This study aimed to investigate the fatty acid composition of zooplankton and common carp larvae in hatcheries at the first seven days of larval rearing. SFA was higher in rotifers before releasing of larvae on = day 1 gain (6.15%), compared to that of day 7, and significantly decreased in the rate of 3.53%. On day 7, total amount of MUFA was increased significantly. Oleic acid was the most dom...

conditional copula-garch methods for value at risk of portfolio: the case of tehran stock exchange market

ارزش در معرض ریسک یکی از مهمترین معیارهای اندازه گیری ریسک در بنگاه های اقتصادی می باشد. برآورد دقیق ارزش در معرض ریسک موضوع بسیارمهمی می باشد و انحراف از آن می تواند موجب ورشکستگی و یا عدم تخصیص بهینه منابع یک بنگاه گردد. هدف اصلی این مطالعه بررسی کارایی روش copula-garch شرطی در برآورد ارزش در معرض ریسک پرتفویی متشکل از دو سهام می باشد و ارزش در معرض ریسک بدست آمده با روشهای سنتی برآورد ارزش د...
