Claim 2

A process for treating damaged tissue of fish comprising topically administering to the fish an aloe vera extract selected from the group consisting of the liquid extract or gel obtained directly from the inner central zones of the leaves of the Aloe Vera plant and the gel reconstituted from powdered aloe vera extract, in an amount effective to promote healing of the damaged tissue.

Claim 3

A process according to claim 1 wherein the extract is added to water containing the fish.

Claim 4

A process according to claim 1 wherein the fish tissue has been damaged by removal of a portion of a slime coating naturally formed on fish skin and further comprising adding at least one slime-replacing compound.

Claim 5

A process according to claim 1 wherein the aloe vera extract is added to water containing the fish in an amount of about 1/4 teaspoonful per 10 gallons of water.

Claim 6

A process for treating diseased or damaged tissue of fish comprising adding to water containing the fish an aqueous aloe vera gel composition comprising between about 5% and about 30% aloe vera gel by volume, up to about 7.5 g/l carboxymethyl cellulose, about 1.3 to about 25 g/l polyvinylpyrrolidone, about 12.5 to about 60 g/l sodium thiosulfate, up to about 2 g/l ethylenediaminetetraacetic acid, about 0.3 to about 1 g/l tris(hydroxymethyl)aminomethane, and about 1.3 to about 4 g/l diazolidinyl urea.

Claim 7

A process for treating diseased or damaged tissue of fish comprising adding to water containing the fish an aqueous aloe vera gel composition comprising between about 5% and about 30% aloe vera gel by volume, up to about 7.5 g/l carboxymethyl cellulose, about 1.3 to about 25 g/l polyvinylpyrrolidone, about 12.5 to about 60 g/l sodium thiosulfate, up to about 2 g/l ethylenediaminetetraacetic acid, about 0.3 to about 1 g/l tris(hydroxymethyl)aminomethane, and about 1.3 to about 4 g/l diazolidinyl urea.

A process according to claim 5 wherein the carboxymethyl cellulose is present in an amount of 2.5 g/l, the polyvinylpyrrolidone is present in an amount of about 10 g/l, the sodium thiosulfate is present in an amount of about 35 g/l, the ethylenediaminetetraacetic acid is present in an amount of about 1 g/l, the tris(hydroxymethyl)aminomethane is present in an amount of about 4 g/l, and the diazolidinyl urea is present in an amount of about 2 g/l.

Claim 9

A process according to claim 6 wherein the aloe vera gel is present in the aloe vera gel composition in an amount of 10% by volume.

Claim 10

An aqueous composition for treating damaged tissue of fish in which at least a portion of a slime coating on the fish has been removed, comprising an aloe vera extract selected from the group consisting of the liquid extract or gel obtained directly from the inner central zones of the leaves of the aloe vera plant and the gel reconstituted from powdered aloe vera extract, in an amount effective to promote healing of the damaged tissue, at least one slime-replacing compound in an amount effective to promote slime replacement of at least a portion of the missing fish slime coating, a dechlorinator selected from the group consisting of sodium thiosulfate and ascorbic acid in an amount effective to neutralize the chlorine in the water, a tris(hydroxymethyl)aminomethane buffer in an amount effective to maintain the pH of the composition at least about 9.0, and a diazolidinyl urea preservative in an amount effective to prevent the inactivity of the aloe vera gel.

Claim 11

An aqueous composition for treating damaged tissue of fish in which at least a portion of a slime coating on the fish has been removed, comprising an aloe vera extract selected from the group consisting of the liquid extract or gel obtained directly from the inner central zones of the leaves of the aloe vera plant and the gel reconstituted from powdered aloe vera extract, in an amount effective to promote healing of the damaged tissue, at least one slime-replacing compound in an amount effective to promote slime replacement of at least a portion of the missing fish slime coating, a dechlorinator selected from the group consisting of sodium thiosulfate and ascorbic acid in an amount effective to neutralize the chlorine in the water, a tris(hydroxymethyl)aminomethane buffer in an amount effective to maintain the pH of the composition at least about 9.0, and a diazolidinyl urea preservative in an amount effective to prevent the inactivity of the aloe vera gel.

Claim 12

A composition according to claim 8 wherein the slime-replacing compound is selected from the group consisting of carboxymethyl cellulose in an amount of up to about 7.5 g/l, polyvinylpyrrolidone in an amount of about 1.3 to about 25 g/l, and mixtures thereof, the dechlorinator is sodium thiosulfate in an amount of about 12.5 to about 60 g/l, the tris(hydroxymethyl)aminomethane is present in an amount of about 0.3 to about 1 g/l, and the diazolidinyl urea is present in an amount of about 1.3 to about 4 g/l, the composition further comprising ethylenediaminetetraacetic acid in an amount of up to about 2 g/l.

Claim 13

A composition according to claim 9 wherein the extract is in the form of an aloe vera gel.

Claim 14

A composition according to claim 10 comprising about 10% by volume of the aloe vera gel, about 2.5 g/l carboxymethyl cellulose, about 10 g/l polyvinylpyrrolidone, about 35 g/l sodium thiosulfate, about 1 g/l ethylenediaminetetraacetic acid, about 0.4 g/l tris(hydroxymethyl)aminomethane, and about 2 g/l diazolidinyl urea.
