A fish hatchery is a place for artificial breeding, hatching, and rearing through the early life stages of animals—finfish and shellfish in particular. [1] Hatcheries produce larval and juvenile fish , shellfish , and crustaceans , primarily to support the aquaculture industry where they are transferred to on-growing systems, such as fish ...
The incubator is an apparatus that is used to regulate environmental conditions such as temperature, humidity and turning for successful hatching of the fertile eggs placed in an enclosure. It is often used for growing bacterial cultures, hatching eggs artificially, or providing suitable conditions for a chemical or biological reaction.
This is a multibillion-dollar industry, with highly regimented production systems used to maximize bird size or egg production versus feed consumed. [9] Generally large numbers are produced at one time so the resulting birds are uniform in size and can be slaughtered (for meat) or brought into production (for eggs) at the same time.
Crocodiles help maintain the balance of Philippine ecosystems such as wetlands; crocodile farming in the Philippines is also geared towards the rescue and conservation of both C. porosus and the "endangered and endemic" C. mindorensis. Crocodile farms also contribute to tourism in the Philippines and offer public education about crocodiles. [1] [2]
The behavior of an amphibian hatchling, commonly referred to as a tadpole, is controlled by a few thousand neurons. [4] 99% of a Xenopus hatchling's first day after hatching is spent hanging from a thread of mucus secreted from near its mouth will eventually form; if it becomes detached from this thread, it will swim back and become reattached, usually within ten seconds.

A transitional stage known as the sac larval stage, lasts from hatching to the complete resorption of the yolk sac. Juvenile stage: Starts when the morphological transformation or metamorphosis from larva to juvenile is complete, that is, when the larva develops the features of a functional fish. These features are that all the fin rays are ...

The entire unit moves horizontally within an aisle, while the shuttles are able to elevate up to the necessary height to reach the load, and can extend and retract to store or retrieve loads that are several positions deep in the shelving. A semi-automated system can be achieved by utilizing only specialized shuttles within an existing rack system.
