Commercial aquaculture is growing worldwide except in Africa where production is still low. With fisheries reaching a stagnating phase, the world and more so Africa will have to look to aquaculture in the future to provide fish products that will likely be needed. In view of this, a study on water quality management was done which specifically looked at the effects of dissolved oxygen saturatio...
در این تحقیق ، غلظت جیوه در بافت عضله ، کبد و آبشش ماهی کفشک گونه تیزدندان (psettodes erumei) و رسوبات در سواحل استان هرمزگان( قشم ،هرمز و جاسک) اندازه گیری شد. نمونه های ماهی به کمک تور ترال کف روب صید شدند . بافت عضله ، کبد و آبشش 45 نمونه صید شده به صورت تصادفی در هر فصل ، پس از زیست سنجی تفکیک و فلز جیوه به روش هضم شیمیایی استخراج شد و غلظت آن توسط دستگاه اسپکتروفتومتر جذب اتمی (aas ) تعیین...
The identities of single cone cells in the retina of Atlantic halibut (Hippoglossus hippoglossus) larvae were studied by in situ hybridisation using RNA probes for the five different halibut opsins. Four different cone opsins (ultraviolet-, blue-, green- and red-sensitive) are expressed in Atlantic halibut at the end of the yolk-sac period, whereas rod opsin is expressed later in development. P...
cDNA libraries were constructed from the following developmental stages (tissues) of the Atlantic halibut (Hippoglossus hippoglossus): 2-cell stage (embryos), 1 day-old yolk sac larvae (trunk) and juvenile (fast skeletal muscle). A total of 4249 high quality expressed sequence tags from the three libraries were clustered into a partial transcriptome of 2124 putative genes. A large proportion of...
in the residential area of the north coast of the persian gulf, consumption of fish is a possible source of exposure to heavy metals and other pollutants, all of which may act as potential risk factors for serious syndromes and fatal diseases. health risks associated with pb, cd, and hg were assessed based on the target hazard quotients (thq), which can be derived from concentrations of heavy m...
Objectives of tradable permit programs are often broader than internalizing an externality and improving economic efficiency. Many programs are designed to accommodate community, cultural, and other non-efficiency goals through restrictions on trading. However, restrictions can decrease economic efficiency gains. We use a policy experiment from the Alaska halibut and sablefish tradable permit p...

Organochlorines were examined in liver and stable isotopes in muscle of fishes from the western Aleutian Islands, Alaska, in relation to islands or locations affected by military occupation. Pacific cod (Gadus macrocephalus), Pacific halibut (Hippoglossus stenolepis), and rock greenling (Hexagrammos lagocephalus) were collected from nearshore waters at contemporary (decommissioned) and historic...
