Blood parrot, also known as Red Fortune God, Fortuna Fish and Fortune Fish, is a species obtained by crossing the males of the red devil (Cichlasomacitrinellum Gfinther) with the females of the Cichlasomasynspilum Hubbs. It is a freshwater tropical ornamental fish and was produced in 1986 in Taiwan. area. Its mouth shape resembles that of a bird, its body is full of red blood, its body is rich and varied, its temperament is gentle, and it has the features of rapid growth, strong disease resistance, and strong adaptability to temperature. It is an ornamental fish species that is popular among consumers and is in the ornamental fish market. It occupies an important place. Since Pinghu City, Zhejiang Province, introduced and tested blood-raising parrots in 2005, it has cultivated the ornamental fish breeding industry as a new industry. After three years of development, it has formed a seedling production, adult culture, product sales, and ornamental fish feed. The industry chain of fishery and fishery business is one of the industries. The industry has a good development situation. It has rich farming experience and mature technology. The author now summarizes the technique of artificial breeding of blood parrots as follows in order to provide technical reference for blood parrot breeding practitioners.
1, adult fish breeding
The adult culture of blood parrots can be divided into pond culture and greenhouse cultivation.
1.1 pond culture
1.1.1 Environmental Facilities Requirements Farms are far away from sources of pollution, the surrounding environment is relatively quiet, communication and transportation are convenient, and water and electricity are sufficient. The water quality of the water sources and the cultured water meet the fishery water quality standards. The pond is rectangular, with long east-west and short north-south. The area is suitable for 2500-3500m2. It can store more than 1.5m of water; Loam or sandy bottom, the bottom is flat, no water leakage, silt thickness is less than 20cm, both ends of the pool into the drainage facilities perfect. One aerator with a power of 1.5kW per 1334m2. Prior to stocking, the ponds should be filled with water for about 10 years, and every 667m2 should be disinfected with 75-100kg of quicklime or 3-4kg of bleach (28% of effective chlorine content).
1.1.2 Water-feed bait Seedlings are watered 80-100cm 7-10d before stocking. When entering the water, they should be filtered with a 60-mesh sleeve-like screen mesh. Then, the fermented and decomposed organic fertilizer should be properly applied according to the condition of the body's thinness to cultivate the basic biological feed.
1.1.3 Quality Requirements Seedlings should be 3cm or more in length, neat in size, consistent in body type, strong in anti-water swimming, no damage to the body surface, no defects in scales and fins, and full and bright eyes.
1.1.4 Seed stocking Stocking water temperature is not lower than 25 °C (eastern China is about the end of May), and the water temperature difference between the adult fish breeding pond and the seedling breeding pond should not exceed 2 °C. Before the stocking, test the water first, and ensure that the medicinal properties of the clear pond are completely disappeared before stocking, and avoid operating in bad weather such as windy or rainy days. Per 667m2 stocking of 1000-12000 tail size, uniform size blood parrot seed, the specific stocking density depending on pond conditions, farming techniques and management levels.
1.1.5 Feeding Management Feeding Feeding adhere to the "Four Sets" principle, feeding high-quality compound feed, the crude protein content of more than 43%, the daily feed to the fish body weight of 6% -7% is appropriate. In practice, the theoretical feeding amount is calculated based on the specifications of the pond fish, combined with the season, weather, water temperature, water quality, and feeding conditions. The feeding is conducted twice daily at 07:00 and 15:00. In the early period of cultivation, with the gradual increase of water temperature, mainly adding water, water injection 3-5cm daily until the water level reaches 1.2m; by mid-to late June, in order to avoid excessive water temperature on juvenile fish growth, Add water to about 1.5m, and maintain this level; in the middle and later stages of cultivation, change the water according to the water quality conditions as appropriate to ensure good water quality and adequate dissolved oxygen. However, the amount of water to be changed each time should not exceed 20%. Maintaining water during cultivation
Main products:
1. 5-ala: 5-ALA (CAS: 5451-09-2) is suitable for a wide range of scientific fields, such as increasing harvest yield or increasing plant green. Supplementary studies from animal cultures of microorganisms or cells related to reactive oxygen species produced from the accumulation of excess porphyrins are used for photodynamic diagnosis of cancer research.
2. Garlic Extract Allicin: allicin has a strong odor and spicy taste, and has immune and anti-fatigue functions. As a restorative herb, garlic can play an important role in balancing stressful life and tired body. In the veterinary field, it can treat respiratory infections and digestive diseases in poultry and livestock.
3. Sophora flavescens Extract: Matrine is an alkaloid extracted from the roots, stems and fruits of the leguminous plant Sophora flavescens by an organic solvent such as ethanol, and belongs to the class of quinolocilidine derivatives lupin alkaloids. Matrine has various pharmacological effects such as antibacterial, antiasthmatic, and white blood cells.
