However, these juveniles often have a higher value than the cultivated species, and their mortality is caused by smaller sizes. These are： red king crab, Japanese sea cucumber, sea urchins, Japanese cucumaria and several species of ascidians and sponges. However, the use of a realized niche, rather than a fundamental one, in selecting the area and depth to install collectors, and also improvement of their design, make it possible to cultivate a target species without reseeding to other constructions. This not only facilitates the cultivation process, but also increases the survival rate of the cultivated and accompanying species, since at the bottom, they reach either marketable or viable size in comfortable conditions.展开更多

Multi-variate analysis （PCA） of all the data was undertaken. The first principal component was positively correlated with chlorides, sulphites, hardness, and negatively correlated with altitude. The second principal component was positively correlated with DO and pH. Results showed that 4 groups of springs could be distinguished on the basis of environmental variables. A small number of springs did not group with the geographically more proximal springs but with another group due to a greater degree of affinity on the basis of the hydrochemical variables.展开更多
