What the machines do

These machines have their own part on working helping us get money from other different countries. Nursery tank systems - These tanks help the oyster larvae survive by eating algae that is stored in the tank. The tank was not in a shape of a water tank or a cylinder it was about one meter high and very wide that it was a size of a swimming pool. Small boats and rafts - The boats and rafts make the job easier. They are designed small to fit through narrow gaps when looking for oysters. Small knives - The knives used in the hatcheries are blunt only the top bit was sharp to help remove oysters of their place. Filter - The filters had different jobs one was to make algae to feed the oyster larvae, the other one was to pump enough water and clean enough for the oysters to survive. Hessian Bags - These bags are hardly made to hold much weight and are easier to carry while working. Racks - Racks were not machines but they help the hatchery to produce more money by killing the bacteria that make you sick.

Exploring the hatchery

Nowadays hatcheries have expanded with more machines than before. The hatchery is not a factory, it is a place for oysters to grow and be harvested and then transported to a factory. The oyster larva has a soft body. It begins to grow an outer skin and when that happens the larvae are old enough to find an obstacle to settle on. The hatchery has many interesting machines and equipment.
