Weather loaches are nutritious and delicious. They ???. Market demand is on the rise. Weather loaches are very adaptable and easy to raise. ???

Zhejiang ??? Bureau through several years of continuous exploration has solved the difficulties of the artificial breeding and fry care of weather loaches, so that weather loach raising now has guarantee of fry type.

Weather loach raising methods are flexible and various. It is both possible to use home yard pond raising and large scale production. They can both be raised alone or be raised along with other aquatic animals.

This film will concentrate on presenting weather loach pond culture techniques and paddy field culture techniques.

Now let us look at pond weather loach culture operation techniques.

First must be built the raising ponds. Loach raising ponds and [other] fish raising ponds have certain differences. When building the ponds, one must consider three factors. Number one is in order to avoid that during the raising process individual loach sizes become inconsistent, achieve feeding(?) consistency, and improve the marketing rate [First, in order to avoid the loaches growing inconsistently, achieve consistent feeding, and improve marketability], pond areas should not be too large, with 100 to 300 square meters being ideal. Second, based on the loach's special ??? ability, and to avoid the loaches escaping, the bottom of the pond must be spread with approximately 20 cm thickness of soft mud, and the top of the pond edges should be 40 cm above the water surface. Pond walls should be hardened or lined with plastic film. Water intake and output mouths construct fish block anti-escape devices. Third, because loach ??? is relatively difficult, one should at the water intake/output mouth dig a fish-concentration pit 30 cm lower than the pond bottom to facilitate ???.
