Ram feeding and suction feeding are on opposite sides of the feeding spectrum, where extreme ram feeding is when a predator swims over an immobile prey item with open jaws to engulf the prey. Extreme suction feeding is demonstrated by sit-and-wait predators that rely on rapid depression of the jaws to capture prey (e.g., frogfish, Antennariidae).
The solunar theory is a hypothesis that fish and other animals move according to the location of the moon in comparison to their bodies. [1] The theory was laid out in 1926 by John Alden Knight, but was said to be used by hunters and fishermen long before the time it was published.
The golden topminnow's diet does not include vertebrate prey, and the most common food sources are seed shrimp and midge larvae with water beetles and mayflies as minor contributors to its diet. [7] Because of its trophic level position, the golden topminnow also has a wide array of predators that feed on smaller, surface feeding vertebrates.

[14] [15] The fish lived in both freshwater and marine environments, first appearing during the Ordovician, and perishing during the Frasnian–Famennian extinction event of the Late Devonian. They were predominantly deposit-feeding bottom dwellers, although there is evidence to suggest that some species took to the water column to be free ...
The aquaculture or farming of piscivorous fish, like salmon, does not help the problem because they need to eat products from other fish, such as fish meal and fish oil. Studies have shown that salmon farming has major negative impacts on wild salmon, as well as the forage fish that need to be caught to feed them.
By that reasoning, Miami’s playoff hopes are toast barring an unexpected blowout loss for a team like Penn State or Georgia in their conference title games on Saturday that somehow drops one or ...
Studies of different size classes of fish have found their diets change with age in some locations, with the changes relating to an increased volume of fish taken. [35] Giant trevally also feed on fledgling sooty terns on Farquhar Atoll snatching them from the water surface and even jumping acrobatically to catch them in the air as seen on the ...
