Abstract
The invention relates to methods, compositions and kits for raising marine fish in freshwater. The methods involve adding at least one Polyvalent Cation Sensing Receptor (PVCR) modulator to the freshwater in an amount sufficient to increase expression and/or sensitivity of at least one PVCR; and adding feed for fish consumption to the freshwater, wherein the feed comprises an amount of NaCl sufficient to contribute to a significant increased level of the PVCR modulator in serum of the marine fish.
Claims21
A method of growing marine fish in freshwater, comprising:
- a) adding at least one Polyvalent Cation Sensing Receptor (PVCR) modulator to freshwater in an amount sufficient to modulate or maintain expression and/or sensitivity of at least one PVCR in one or more tissues;
- b) transferring the marine fish to the freshwater, modified according to step a);
- and
- c) adding feed for fish consumption to the modified freshwater, wherein the feed contains an amount of NaCl sufficient to contribute to a significant increased level of said PVCR modulator in serum of the marine fish.
A method of transferring marine fish to freshwater, comprising:
- a) adding at least one Polyvalent Cation Sensing Receptor (PVCR) modulator to the freshwater in an amount sufficient to modulate or maintain expression and/or sensitivity of at least one PVCR in one or more tissues;
- b) transferring the marine fish to the freshwater, modified according to step a);
- and
- c) adding feed for fish consumption to the modified freshwater, wherein the feed contains at least about 1% NaCl by weight.
A method of growing marine fish in freshwater, comprising:
- a) determining the level of at least one PVCR modulator in freshwater;
- b) based on the level determined in step a), adding said PVCR modulator to the freshwater in an amount sufficient to modulate or maintain expression and/or sensitivity of at least one PVCR in one or more tissues;
- c) transferring the marine fish to the freshwater, modified according to step b);
- and
- d) adding feed for fish consumption to the modified freshwater, wherein the feed contains an amount of NaCl sufficient to contribute to a modulated level of said PVCR modulator in serum of the marine fish.
A method of growing marine fish in freshwater having between about 0.3 mM and about 10.0 mM of calcium and between about 0.5 mM and 10.0 mM of magnesium, the method comprising adding feed to the freshwater wherein the feed contains an amount of NaCl sufficient to contribute to a significant increased level of said PVCR modulator in serum of the marine fish;
- wherein modulated expression of at least one PVCR occurs in one or more tissues.
A method of transferring marine fish to freshwater, comprising:
- a) transferring the marine fish to freshwater having magnesium and calcium in the freshwater in amounts sufficient to modulate or maintain expression and/or sensitivity of at least one PVCR in one or more tissues, and
- b) adding feed to the freshwater, wherein the feed contains at least about 1% NaCl by weight.
A method of growing flounder in freshwater, comprising:
- a) transferring the flounder to freshwater having at least one PVCR modulator in an amount sufficient to modulate or maintain expression and/or sensitivity of at least one PVCR in one or more tissue;
- b) adding feed for fish consumption to the freshwater, wherein the feed contains an amount of NaCl sufficient to contribute to a significant increased level of said PVCR modulator in serum of the flounder.
A method of growing marine fish in freshwater, comprising:
- a) adding at least one PVCR modulator to freshwater in an amount sufficient to modulate or maintain expression and/or sensitivity of at least one PVCR in one or more tissues;
- b) transferring the marine fish to the freshwater, modified according to step a);
- and
- c) adding feed for fish consumption to the modified freshwater, wherein the feed contains an agent that contributes to a significantly increased level of said PVCR modulator in serum of the marine fish.
A method of growing marine fish in freshwater, comprising:
- a) transferring the marine fish to the freshwater;
- b) adding at least one PVCR modulator to freshwater in an amount sufficient to modulate or maintain expression and/or sensitivity of at least one PVCR in one or more tissues;
- and
- c) adding feed for fish consumption to the modified freshwater, wherein the feed contains an amount of NaCl sufficient to contribute to a significant increased level of said PVCR modulator in serum of the marine fish.
