Hydroponics has been recognized as a viable method of producing vegetables (tomatoes, lettuce, cucumbers and peppers) as well as ornamental crops such as herbs, roses, freesia and foliage plants. Due to the ban on methyl bromide in soil culture, the demand for hydroponically grown produce has rapidly increased in the last few years.

culture can be obtained from other culturists or hatcheries. Culture systems can come in a variety of shapes and sizes but should be kept as simple as possible. A plastic shoebox or shallow bin with high surface area and moderate depth (about 6 to 10 cm deep) makes an ideal culture container. The culture container should have a loosely fitting lid

In the wild or in culture ponds, females lay a strand of eggs, called ribbons, over a substrate, such as sand, gravel, or vegetation, and then several males will fertilize the eggs. Females deposit between 79 to 233 eggs/g of fish (Hart et al. 2006). In commercial culture settings, there are three methods of spawning yellow perch.

Culture Methods. The main methods for culturing sea cucumber include pond farming, pen culture, sea ranching, and tank culture. Stocking larger juveniles in pond farming, pen culture, and sea ranching usually results in a higher survival rate but this also means the cost of production at the nursery level will be more expensive.
