In order to intensify the protection and sustainable use of Sanguinolaria diphos (Linnaeus) resources, our station utilized wild S. diphos resources in the Nanri Island, Putian to carry out scale breeding technology research. The technical research results of S. diphos large-scale breeding in the Pinghai Ostrea cucullata (Born) Breeding Farm, Putian in 2012 was presented in this paper, and the process of large-scale breeding was also described. We explored the breeding habits, the process of embryonic development and environmental requirments of S. diphos, and broke through the key technical points such as the requirements of the attached bottom quality, food demand and water quality. We finally formed a S. diphos breeding technology and process.

Abstract: The effects of concentration of nitrogen and phosphorus and different culture methods on the growth of green macroalgae Caulerpa lentillifera were studied. Results showed that concentration of nitrogen had different effect on the growth of C. lentillifera. The wet weight of C. lentillifera was the highest when it was cultured in 15 mg?㎏-1 within the tested range of nitrogen concentration (0 mg?㎏-1~50 mg?㎏-). The effects of concentrations of phosphorus on the growth of C. lentillifera were similar. The wet weight of C. lentillifera was the highest in the 4 mg?㎏-1 in the tested treatments (0 mg?㎏-1~5 mg?㎏-1). Different culture methods had large influence on the growth of C. lentillifera. C. lentillifera was the best when it was cultured in basin among the flask, basin and nylon rope treatments.
