An anti-hypertensive fish protein hydrolysate is provided, wherein the fish is of the genus Salmo or Oncorhynchus, and wherein the fish protein hydrolysate comprises at least 1 peptide selected from the group consisting of: Leu-Ala-Phe, Leu-Thr-Phe, Ile-Ile-Phe, Leu-Ala-Tyr, Ile-Ala-Tyr, Val-Phe-Tyr, Tyr-Ala-Tyr, Val-Leu-Trp, Ile-Ala-Trp, Tyr-Ala-Leu and Tyr-Asn-Arg. Methods of making and methods for using such fish protein hydrolysates are also provided.

The invention discloses a biosensing detection method used for identifying a salmo salar and a rainbow trout. The biosensing detection method comprises the following steps: the step 1 of extracting genome DNA of a sample to be detected, using a specific primer pair of the salmo salar to carry out PCR reaction with the genome DNA of the sample to be detected as a template and obtaining a PCR amplification product I of the sample to be detected; the step 2 of adding the PCR amplification product I obtained in the step 1 to the surface of an electrode decorated by an anchoring acceptor for reaction; the step 3 of detecting an electrochemistry signal of an electrochemistry activity labeled molecule and deciding that the sample to be detected comes from the salmo salar if the electrochemistry signal of the electrochemistry labeled molecule exists. The specific primer pair of the salmo salar comprises the electrochemistry activity labeled molecule and an anchoring labeled molecule on the upstream of a base sequence respectively, and the anchoring labeled molecule can be captured by the anchoring acceptor to enable the PCR amplification product with the anchoring labeled molecule to be captured by the surface of the electrode. The method is suitable for fish samples of any growth stage and in any shape.

The invention provides a hypothermic anesthesia transportation method for live Oncorhynchus mykiss, the method comprising following steps: 1) feed deprivation: food provisioning for Oncorhynchus mykiss is stopped for 2-3 days before transportation; 2) cooling and anesthesia treatment: water tanks are filled with cooled aquaculture water of 1-2 DEG C; the water temperature is maintained; anesthetic is added to the water and mixed well. The Oncorhynchus mykiss deprived of food is weighed and then put in the aquaculture water and quick cooling and anesthesia are performed. The Oncorhynchus mykiss is taken out of water surface when the activity ability of the fish is nearly exhausted. By this time, the fish bodies are in the state of hypothermic anesthesia and then they are to be encased. 3) the Oncorhynchus mykiss are transported by packing transportation or water track transportation. After arriving at a destination, The Oncorhynchus mykiss are brought back to life and the temperature of aquaculture water is gradually increased to normal level. The hypothermic anesthesia transportation method has following beneficial effects: no matter how much the transportation volume of live fish is, the transportation method can be performed with low cost, simple, flexible and easy operation; and the economic benefit can be guaranteed by high rate of survival of fish after transportation.

The invention provides a production method of Oncorhynchus Mykiss triploid fry. The production method including fertilizing fertilized eggs of Oncorhynchus Mykiss for 12-14 min at the temperature of 7 DEG C to transfer to 240mg / L 6-DMAP (6-Dimethylaminopurine) solution at temperature at 12-14 DEG C for soaking for 14-16 min, and then transferring the fertilized eggs to hatching water to hatch normally. After around 50 days, the Oncorhynchus Mykiss triploid fry are hatched from the fertilized eggs. Eyeing rate of the fertilized eggs during hatching is more than 68%, hatching rate of the fry reaches 90%, the fry are detected by a flow cytometry, rate of triploid reaches 81%. By the aid of the production method of the Oncorhynchus Mykiss triploid fry, the problems of precocious puberty, individual miniaturization, disease breeding and the like on cultivation individuals due to long-term inbreeding and lack of systematic select breeding during cultivation of the Oncorhynchus Mykiss, and the production method has good market value.
