Scope
Scope: This document specifies the terms and definitions, site selection and layout, pre-cultivation preparations, parental selection and breeding, larval cultivation process, quality requirements for larvae, hatching and transportation, and reference diagrams for standardized larvae production for the production of Artemia franciscana larvae. This document is applicable to the large-scale cultivation of Artemia franciscana artificial larvae. Main technical content: Site selection and layout 4.1 Site selection The site should be located in a sheltered, sunny area close to the open sea, with a location suitable for building elevated water tanks. The water quality should be good, free from pollution sources such as industry, agriculture, and residential areas. The seawater salinity should be between 25 and 30, and not be affected by heavy rainfall. Transportation, communication, and power conditions should be convenient, and freshwater resources should be abundant. 4.2 Site layout The Artemia conservation room, parental breeding room, larval cultivation room, and bait cultivation room are the main components of the entire larval cultivation work. They should be located in a sunny area with no obstructions around. The seawater supply system, including sedimentation tanks, water towers, sand filters, ultraviolet sterilization rooms, and water storage tanks, should be built as high as possible to allow the larval water to flow naturally. The heating system boilers should be built in the downwind direction of the prevailing wind. The generator and fan rooms should be far away from the larval cultivation rooms and office and living areas. Other ancillary facilities such as the oxygen supply system and drainage system should be reasonably proportioned to the production scale of the larval cultivation site. 4.2.1 Seawater supply system The seawater supply system mainly includes pumps, sedimentation tanks, water towers, sand filters, and ultraviolet sterilization
