Chemoreception in the pigfish, Orthopristis chrysopterus: The contribution of amino acids and betaine to stimulation of feeding behavior by various extracts

Feeding stimulants in semipurified diets for juvenile lake sturgeon, Acipenser fulvescens Rafinesque*

“…The control diet contained approximately 45% crude protein, which is 5% higher than the recommended level for optimal growth of white sturgeon juvenile (Moore, Hung & Medrano 1988), On the contrary, the soluble peptides, particularly the short polypeptide chains of low molecular weight (technical document no. It is worth noting that incorporation of 2% betaine alone was ineffective in making lake sturgeon feed on the casein-based semipurified diet, in contrast with previous work on the white sturgeon (Patterson, Lellis & Barrows 1994) as well as with many fish (Carr, Blumenthal & Netherton 1977;Goh & Tkmura 1980a, 1980bGill 1989) and crustaceans (Carr 1978). Sopropeche S,A,) contained in the fish protein concentrate, probably stimulated the consumption of food by acting upon the olfactory and/or gustatory receptors located on fish body and in the mouth.…”

“…This suggests changes in attractant-stimulant preferences in relatior; to fish age (Mackie, Adron & Grant 1980;Shparkovskiy, Pavlov & Chinarina 1983). It is worth noting that incorporation of 2% betaine alone was ineffective in making lake sturgeon feed on the casein-based semipurified diet, in contrast with previous work on the white sturgeon (Patterson, Lellis & Barrows 1994) as well as with many fish (Carr, Blumenthal & Netherton 1977;Goh & Tkmura 1980a, 1980bGill 1989) and crustaceans (Carr 1978). Finally, the present study demonstrates that, in lake sturgeon feeding, the combination of betaine and fish protein concentrate is an alternative to tubifex and white worm extracts as previously reported (Binkowski & Meyers 1983).…”

Construction of a taste‐blind medaka fish and quantitative assay of its preference–aversion behavior

“…Fish also respond to chemical stimuli from a distance. For example, if a solution containing amino acids is dropped into the water, they respond by swimming vigorously and searching for food (Carr et al 1977; Hara 2006; Lindsay & Vogt 2004). This results from the rapid diffusion and detected of the chemicals by the fish olfactory system.…”
