Embodiment Construction

[0013] The following examples will further illustrate the present invention.

[0014] 1. Preparation of the cultivation pond: choose a muddy earth pond with an area of ​​1300m2 as the cultivation pond 2 , pond age 2 years. The water entered on February 15th, the water depth was 0.7~0.8m, and the salinity was 13‰~14‰. The incoming water was filtered through a 120-mesh silk screen, and the bleaching powder was used to strictly disinfect the available chlorine at a concentration of 20mg / L. After 48 hours of disinfection, use bottom aeration to aerate for 24 hours, and the oxygenation power is 2kW. Sprinkle 25kg of silicate-rich biological compound organic fertilizer soaked in advance for 3~4 hours in the morning on the second day after aeration. After the first fertilization, apply 10kg of bio-composite organic fertilizer every sunny morning until the water transparency is controlled at 20-30cm and the concentration of diatoms reaches (3-5)×10 3 ind / mL.

Abstract

The invention discloses a breeding method of Rillengrundel (Parapocryptes serperaster (Richardson)), relates to an aquaculture method, and provides the breeding method of Rillengrundel. The breeding method comprises the steps of: preparing a cultivation pool; collecting and cultivating a parent fish; carrying out natural oviposition and manual handling, and cultivating fish fry by rich water. Theproblem that the parent fish of Rillengrundel does not eat any feed in a cement pit is solved by directionally cultivating diatom in an earthen basin; planktonic animals are killed by trichlorphon for creating a good mouth-open feeding environment for larval fishes of Rillengrundel; the problem that the larval stage feed of the larval fishes of Rillengrundel is grabbed by the planktonic animals is sloved; ostrea rivularis is bred in the earthen basin by a hanging method; the problem of the larval stage feed source in the earthen basin of the larval fishes of Rillengrundel is solved; the problem of mouth-open feeding difficulty of the larval fishes of Rillengrundel is solved, and a positive and effective way is provided to improve the breeding quantity of Rillengrundel.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to a breeding method of a lizard-shaped paraflattooth goby. Background technique [0002] Lizard-shaped paraflat-toothed gobies, English name: Rillengrundel, Latin name: Parapocryptes serperaster (Richardson, 1846), belonging to the suborder Gobioidei (Gobioidei), family Gobiidae, Parapocryptes serperaster The genus (Paraopcryptes), commonly known as white pigeon fish, white turtle or white flower fish. Synonyms of the goby include: Apocryptes henlei Bleeker, 1849; Apocryptes macrolepis Bleeker, 1851; Apocryptes serperaster Richardson, 1846; Boleophthalmus smithi Fowler, 1934; ; Chinese synonym includes the large scale paraflat tooth goby. The lizard-shaped paraflattooth goby is a small warm-water fish that inhabits brackish water in estuaries and coastal tidal flats, and also lives in freshwater waters in the lower reaches of rivers. In my country, the wild distribution area of ​​gobies ...
