Selanjutnya upaya kultivasi secara massal dilakukan untuk pemenuhan kebutuhan hatchery. Penelitian ini bertujuan untuk mengetahui nilai nutrisi pakan alami Skeletonema costatum, Thallassiosiera sp, Chlorella sp. dan Chaetoceros calcitran s dari hasil produksi kultivasi massal. Laboratorioum Alga Pakan Alami, Balai Besar Pengembangan Budidaya Air Payau Jepara. Isolate 5 ml dari setiap jenis fitoplankton digunakan sebagai sumber pada kultivasi dengan media gallon 20 liter selama 15 hari atau sampai dengan tercapainya puncak populasi. Transfer ke media 1 ton dilakukan setelah puncak populasi tersebut. Kedua jenis media memanfaatkan pupuk dari formula Conwy. Densitas fitoplankton diamati setiap hari dengan menggunakan haemocytometer. Setelah tercapai puncak populasi, maka fitoplankton akan dipanen dengan menyaringnya dengan 2 μm. Hasil panen digunakan untuk analisis nutrisi. Kandungan nutrisi fitoplankton menunjukkan kisaran nilai protein : 21.85 – 37 % ; lemak : 2.41 – 10 % dan karbohidrat : 17 – 21 %. Sedangkan asam lemak menunjukkan kisaran nilai yang cukup tinggi, khususnya pada omega 3 : 0.911 – 3.738 % ; omega 6 : 15.591 – 38.002 % dan omega 9 : 0.292–15.112 %. Nilai nutrisi tersebut tidak berbeda dengan kultivasi laboratoris. Kata kunci : Kandungan Nutritif, Alga, Skeletonema costatum, Thallassiosiera sp, Chlorella sp,.

While the study to mass cultivation as the requirement for natural feed of marine biota larvae was already develop in the hatchery, and need to explore into mass cultivation for an alternative purpose. The aim of the study is to determine the nutrition contents of four type phytoplankton, Skeletonema costatum, Thallassiosiera sp, Chlorella sp. and Chaetoceros calcitrans based on mass cultivation. The research was conducted in the Laboratory of Natural Food, Brackishwater Aquaculture Development and Research Center, Jepara. The 5 ml isolate of each phytoplankton were cultivate in the 20 litter gallon for 15 days or until the reach of the density. After the peak density of every phytoplankton, it will transfer into 1 ton media. Each treatment was three replicate. Each approach using the enrichment media based on Conwy formula. The density was daily monitor using haemocytometer. After the reach of peak population density, the algae was filtered using 2 μm screen. The algae then store in the refrigerator for nutritive determination. The average nutritive content in the algae show a range value of protein : 21.85 – 37 % ; lipid : 2.41 – 10 % and carbohydrate : 17 – 21 %. While the lipid acid show a high range value, especially for omega 3 : 0.911 – 3.738 % ; omega 6 : 15.591 – 38.002 % aand omega 9 : 0.292 – 15.112 %.
