Ancient Fish Fossils Give Insight Into Evolutionary History Of Gobioid Order
2013-05-16 13:51:46

Fish fossils that are about 23 million years old give unprecedented insight into the evolutionary history of the gobioid order, one of the most species-rich groups among the modern bony fishes.

Effects Of Changing Ocean pH May Result In Increase In The Hearing Sensitivity Of Fish

University of Miami Rosenstiel School of Marine & Atmospheric Science Ocean acidification, which occurs as CO2 is absorbed by the world's oceans, is known to negatively impact a wide variety of marine animals ranging from massive corals to microscopic plankton. However, there is much less information about how fish may be impacted by acidification, should carbon emissions continue to rise as a result of human activities. In a new study published in the Proceedings of the National...

Fish Ear Bones Can Offer Clues To Impacts Of Climate Change In Aquatic Environments

The earbones, or 'otoliths', help fish to detect movement and to orient themselves in the water. Otoliths set down annual growth rings that can be measured and counted to estimate the age and growth rates of fish.

The more anchovies grow, the greater the probability of their survival, and it is precisely those born at the peak of the season of egg-laying and promptly moving out to the ocean area which enjoy optimum growth.

By Longenecker, Ken Abstract: Estimating body size of fishes from remains recovered from piscivores, archaeological sites, and sedimentary deposits is desirable but rarely accomplished because the relationships between the size of a fish and its durable anatomical structures are largely unknown.

By Pondella, Daniel J II Froeschke, John T; Wetmore, Lynne S; Miller, Eric; Valle, Charles F; Medeiros, Lea Abstract: The yellowfin croaker, Umbrina roncador Jordan & Gilbert, 1882, is a common nearshore and surf-zone species in the southern California bight.

By Luntz, Stephen Increasing ocean acidity as a result of carbon emissions may be making it hard for fish to form symmetrical otoliths (ear bones), creating a further threat to the health of coral reef ecosystems as fish with asymmetrical ear bones struggle to find their way to the safety of coral reefs.
