- This article gives some brief explanation about type of freshwater rotifers.
- Rotifers have been divided into four categories which relate to their appearance and habitat preferences rather than to their taxonomic classification.
- Bdelloid Rotifers - Common in ponds and on mosses, are soft-bodied, and have leech-like movements.
- Loricate Rotifers - Those having a characteristic hardened or semi-hardened body shell.
- Planktonic Rotifers - Normally found in the open surface waters of a pond or stream.
- Sessile Rotifers - Found attatched to submerged plants and rootlets in ponds and streams.
- Owner of the website also invite any company that relevant to their content to promote knowledege-based product (product that need proper understanding and knowledge for customer).

- This site give some explaination how they culture their betta.
- They used Bunkhouse consists of 4 rain gutters with leaf guards each one 10’0” long.
- Each row holds 27 bunks (beanie baby boxes).
- Each box holds 1/3 gallon of water.
- The water flows clockwise.

- This article proves that rotifers are very easy to culture at home.
- Rotifers feed best on microalgae, typically in the 1 to 10 micron range.
- The most commonly used algae is called Nannochloropsis.
- Other commonly used algae are Isochrysis and Pavlova.

- The three phases of freshwater prawn culture are hatchery, nursery, and pond grow out.
- This article provides detailed information on the design and operation of a freshwater prawn hatchery and nursery facility.
- That would enable the producer to culture juveniles for stocking his own production ponds or for sale to other grow-out operations.
- The hatchery and nursery stages are labor intensive and exacting, and require relatively high expertise for success.
- A limited number of postlarvae and juvenile suppliers currently exist, and an increase in demand will eventually lead to more enterprises that deal exclusively in the production and sale of seedstock.

- Nauplii of the brine shrimp artemia constitute the most widely used food item.
- Over 2000 metric tons of dry artemia cysts are marketed worldwide for on-site hatching into 0.4 mm nauplii.
- Those cysts are available year-round in large quantities along the shorelines of hypersaline lakes, coastal lagoons and solar saltworks scattered over the five continents.
- After harvesting and processing, cysts are made available in cans as storable ‘on demand’ live feed.
- Upon some 24-h incubation in seawater, these cysts release free-swimming nauplii that can directly be fed as a nutritious live food source to the larvae of a variety of marine as well as freshwater organisms.
- Its use as a food for the culture of larval organisms began in the 1930’s.
- During the 1940’s, most commercially available brine shrimp cysts represented collections from natural saline lakes and coastal saltworks.
- Early pioneers exploited in 1951 the cyst production of Artemia at the Great Salt Lake in Utah, USA.

- Species of the freshwater prawn genus Macrobrachium are distributed throughout the tropical and subtropical regions of the world.
- Predominant species being produced is Macrobrachium rosenbergii.
- Macrobrachium rosenbergii is indigenous to South and Southeast Asia, northern Oceania, and the western Pacific islands.
- This species has been transferred from their natural location to many parts of the world.
- This transfered initially for research purposes and ultimately for commercial production.

- This manual is an adaptation for Zambian conditions.
- Has been compiled from four titles of the FAO Better Farming Series.
- This version has been prepared by the FAO Fish Culture Development Project in Zambia for the use of extension workers dealing with small scale fish farmers.

- This study has been conducted by Japan International Research Center for Agricultural Sciences.
- The study is based on Vietnamese government major target species of the country's aquaculture sector.
- Until the beginning of 2000, the supply of hatchery-reared M. rosenbergii did not meet the growing need for commercial prawn.
- This problem lead Japan International Research Center for Agricultural Sciences (JIRCAS) and Vietnam's Cantho University initiated a collaborative research in 1995.
- Their main studies is to jointly developed a new and improved means of seed production technology for this species.
