Live Feed Culture Overview

Live feed culture is vital for aquaculture, encompassing organisms consumed by economically significant fish.
It is categorized into two groups: phytoplankton (plant-based) and zooplankton (animal-based).

Phytoplankton Characteristics

Comprises unicellular, colonial, or filamentous organisms.
Functions as primary producers in aquatic ecosystems through photosynthesis.
Invisible to the naked eye; visible as green patches when abundant.
Includes microalgae species such as diatoms, dinoflagellates, and cyanobacteria.
Examples: Chlorella, Nannochloropsis, Skeletonema, Dunaliella, Chaetoceros, Scenedesmus, Arthrospira, Closterium, Isochrysis, Navicula, Spirogyra, Oscillatoria, Westella, Anabaena.

Zooplankton Characteristics

Comprised of small aquatic animals and protozoans.
Key consumers of phytoplankton, obtaining energy and nutrients for survival.
Generally visible to the naked eye and found in the water's mid-layer.
Includes species such as Rotifer, Daphnia, Moina, Tubifex, Copepod, and Artemia sp.

Indoor and Outdoor Culture Techniques

Various techniques are employed to cultivate live feed for aquaculture, with distinctions between indoor and outdoor methods.

Harvesting Techniques

Specific practices are utilized to efficiently harvest both phytoplankton and zooplankton for use in aquaculture.

Assessment Methods

Continuous assessment accounts for a total of 100% of the evaluation.
Breakdown of components includes theory tests (30%), practical work (60%), and case studies (10%).
