This garden pond has two ponds separated by a waterfall with a one-foot drop; generally, the fish in the upper pond are smaller, and ones in the lower pond are larger. Ponds may be created by natural processes or by people; however, the origin of the hole in the ground makes little difference to the kind of wildlife that will be found in the pond.

The pond also is home to various species of crab (pāpaʻi), shrimp (ʻōpae), and eel (puhi). [1] When they are small enough, fish enter the fishpond via the sluice gates to feed on phytoplankton and limu. [5] They then remain within it because of the abundance of food and become too large to get back into Kāneʻohe Bay via the sluice gates. [5]
Hence, introducing fish to a pond can have seriously detrimental consequences. In some parts of the world, such as California, the vernal ponds have rare and endangered plant species. On the coastal plain, they provide habitat for endangered frogs such as the Mississippi Gopher Frog. [20] Often groups of ponds in a given landscape - so called ...
Taro fish ponds were usually located close to the sea and contained surplus of fish. Fish were also able to directly enter the taro patch-fishponds from the sea through newly created artificial estuary. [5] Fish in these ponds thrived and were able to survive the transition from seawater to freshwater.
Even using conservative estimates, freshwater fish extinction rates in North America are 877 times higher than background extinction rates (1 in 3,000,000 years). [32] Projected extinction rates for freshwater animals are around five times greater than for land animals, and are comparable to the rates for rainforest communities. [ 24 ]
