From bare flat to reed zone , theconcentration of protein declined with diatom quantity which influenced the activity of proteinase . it suggested that proteinase in the sediments was probably produced by diatom , and the activity of proteinase was decided by the types of organic matter but not the concentration of organic matter 從光灘到蘆葦帶,硅藻數量逐漸降低,導致沉積物中蛋白質含量降低,影響著蛋白酶的活性,也可能說明蛋白酶主要來源于藻類,因此蛋白酶活性的高低更決定于有機質的類型而與有機質總量無關。

The main feed at this time consists of brine shrimp larvae , oyster eggs and diatoms spiruline , skeletonema costatum . however other zooplankton such as copepoda and rotifera can also be used . during the mysis stage the bodies of the fry become larger and so are able to ingest the nauplii of the brine shrimp along with spirulina and 糠蝦期幼蟲個體較大,已能攝食豐年蝦無節幼蟲,拌用螺旋藻,蝦苗丹喂飼,其存活率有意想不到的好,將螺旋藻與豐年蝦無節幼蟲,蝦苗丹等配合一起喂飼,其存活率高的原因,在于豐年蝦無節幼蟲亦能攝食螺旋藻蝦苗丹,可增加豐年蝦無節幼蟲的存活率,不僅能節省豐年蝦外,又能避免水質惡化不需要常換水。
