in this study, the diversity and distribution of economical bony fishes in less-than-ten-meter depths, cpue and population features such as total length, weight and age were investigated in the southern part of the caspian sea in 1385-6. sampling was done in five regions: amir abad, larim, izdeh, kheyroud, and nashtarood with gilnet in mesh sizes of 26, 33, 40, 60, 100, and 150 mm. in total, 22...

REGIONAL EXTINCTION RISK AND CONSERVATION PRIORITIES FOR PERSIAN GULF MARINE BONY FISHES Jack R. Buchanan Old Dominion University, 2016 Advisor: Dr. Kent Carpenter Around the world, protected areas are the primary conservation measure used to combat biodiversity loss; however, these are often established without comprehensive species-specific information, leading to placement in areas that ofte...

Blood Vascular System, Endothelial Cells, Lymphatics, Bony Fishes Blood distribution in the systemic circulation of bony fishes is effected by a dualistic construction of the vascula­ ture: A secondary arterial system originates from the well known (primary) arteries by multiple root-like shunt vessels. These secondary arteries and the vessels they supply should no longer be regarded as lymphat...

Beginning with Waite’s (1923) Fishes of South Australia, the marine fishes of South Australia (SA) have been increasingly well documented. Waite, Scott (1962) and Gomon et al. (1994) have recorded >210 species of cartilaginous and bony fishes for Gulf St Vincent (GSV) and Investigator Strait (IS). While this is potentially a bewildering array of sizes, shapes and colours, observant fishers and ...

Vertebrate genomes contain thousands of conserved noncoding elements (CNEs) that often function as tissue-specific enhancers. In this study, we have identified CNEs in human, dog, chicken, Xenopus, and four teleost fishes (zebrafish, stickleback, medaka, and fugu) using elephant shark, a cartilaginous vertebrate, as the base genome and investigated the evolution of these ancient vertebrate CNEs...

Although chewing has been suggested to be a basal gnathostome trait retained in most major vertebrate lineages, it has not been studied broadly and comparatively across vertebrates. To redress this imbalance, we recorded EMG from muscles powering anteroposterior movement of the hyoid, and dorsoventral movement of the mandibular jaw during chewing. We compared muscle activity patterns (MAP) duri...
