UMT MOOC: Ornamental Fish Culture - Topic 7: Seed Production - Factors to be Considered for Feeding - Zooplankton : Artemia & Copepods

Continue from previous post.

Artemia
Also known as Brine Shrimp is a cost effective, easy, and readily available live feed used in aquaculture. One key characteristic of Artemia is the ability to produce dormant eggs (cysts) which can be stored (average shelf span of 2 years) and hatched (within 24 hours or 36 hours if the cysts were stored in fridge) later as shown in the video below. Also, Artemia serves as intermediate feed during the transition period before switching to Moina or formulated feed. The only downside, depending on the grade (hatching rate), Artemia is quite expensive.


Copepods
This is microscopic organism or crustaceans (like shrimp) in the marine or freshwater food chain. These organism feeds on Phytoplankton or bacteria. As live feed, it acts as supplemental intermediate feed for both Rofier, Artemia, and Miona. Similar to these live feeds, Copepods is easily cultured and contains nutrient which improve the growth, survival, and pigment development.
