摘要： The present disclosure provides a method for artificial rearing of porcupine pufferfish fries in indoor cement ponds. The method includes the following steps: nursery pond preparation, ponding of newly hatched prelarvae, feeding strategies at fry rearing stages, water quality management during fry rearing, separate ponding of fries, and emergence of fries. Compared with the prior art, the method realizes large-scale production of artificial rearing of porcupine pufferfish fries through a strict control of the water quality and environmental conditions of a nursery pond, along with scientific and reasonable feeding and operation management based on biological characteristics and nutrient requirements of the porcupine pufferfish at different fry breeding stages.

摘要： Provided is a method for artificial rearing of porcupine pufferfish fries in indoor cement ponds. The method includes the following steps: indoor cement pond preparation, release hatched larvae into the indoor cement pond, feed and manage the larvae at different sub-stages of the fry rearing stages, water quality management during fry rearing, separate ponding of fries based on size of the fries, and transfer the fries to net cages or outdoor ponds when the fries reach a minimum length. The indoor cement pond preparation step may include disinfecting the pond and regulating the water quality. During the rearing stage, the method may include stimulating anti-stress physiological response of the larvae. The method may transfer fries with an average total length of more than 2.0 cm into net cages or outdoor ponds for aquaculture after 45 days of the rearing stage.
