3If ammonia and nitrite are being measured, water can be exchanged on the basis of
these maximum allowed levels: Unionized ammonia, 0.1 ppm; nitrite  0.1 ppm (use tables to determine�
unionized ammonia from TAN) (Treece and Fox, 1993; FAO, 2007a).
4Use the following mesh micrometer sizes for water exchange: mysis: 300 μm screen; PL1-4, 400 μm; PL5-8, 500 μm; PL9-12, 700 μm.
5Feed Artemia in the evening or split into 3 feeds.

7Treece and Fox (1993)
8Zoea 3 and Mysis 1 feeds are live, frozen or heat killed Artemia.
9If Artemia are evident the next morning, establish relative to the initial density if "few",
"some" or "all" remain and adjust the feeding accordingly. If "few", follow the programme.
If "some", feed the same amount as the day before. If "all", do not feed more that day.
10Note that this is for 1 million animals, so adjust feeding according to actual larval numbers.
11Adjust feed for the actual larval count per litre so that the budget is met.
12All numbers fed are less than the daily consumption reported by Emmerson (1984).
Emmerson (1984) found that F. indicus consumed 95 Artemia nauplii per day during the Zoea III�
to Mysis I stage, 31 nauplii per day during Mysis II and Mysis III and 143 Artemia per day during Mysis II and PL1.
