“…The cover is a pathway for fish to evacuate into the ADP, and prevents people from falling in while managing the ponds. In the previous study, the ADP is an underground structure that secures a shelter space for fish to escape from adverse conditions during the dry season [19]. Also, ADP was verified to be both an effective fish shelter and a natural habitat area for endangered fish species [19].…”

“…This is due to the water temperature of the study site being below the lethal temperature, as the bitterling showed the highest thermal stress of all fish under a physicochemical environment, but reducing the valid part of thermal stress gave it the dominant position in the survival competition against other species. In addition, ADP can create the preference environment (e.g., water column) [19] and appropriate winter habitat for positive conditions to survival of the bittering, and further study is in progress to validate the ecological functions of the ADP.…”

“…As mentioned, since excessive rises in water temperature in aquatic environments can be detrimental to the reproduction and growth of fish, there has been ongoing research into the functions of fish shelters [14][15][16][17][18][19][20][21][22]. Previous studies have found that fish shelters can be used to prevent untimely predator encounters [14,15], to enable the survival of physical disturbance events such as floods or droughts, and to maintain or increase fish populations through enhancing survival rates [19]. However, most studies have emphasized the complexities of fish shelter structures, and have focused on the vulnerability of prey fish.…”

Therefore, in this study, we tried to investigate water quality characteristics and to verify the ability to mitigate thermal stress of fish when ADP was applied to a shallow pond.…”

This study evaluated water quality variations in an artificial deep pool (ADP), which is an underground artificial structure built in a shallow pond as a fish shelter. The water temperature, pH, dissolved oxygen (DO), and electrical conductivity (EC) were measured on an hourly basis in the open space and inside the ADP, and a phenomenological study was performed, dividing seasons into normal and rainy seasons and environments into stagnant and circulating conditions. The results showed that the water quality parameters inside the ADP exhibit lower fluctuations and diurnal variations compared with the open space. On average, the water temperature inside the ADP is lower than outside it by 1.7-3.7 • C in stagnant conditions, and by 0.6-0.7 • C in circulating conditions during early summer. Thermal stratification occurs inside the ADP but is temporarily disturbed due to the mixing from the forced circulation and the rainwater input through rainfall events. The ADP provided a constant and optimal water temperature for living and spawning for bitterling (i.e., 15.0-21.0 • C), which dominated in experimental pond during spring to summer. Most importantly, the ADP was able to significantly reduce the thermal stress of the fish in the study site, and as a result, the bitterling, a cool water fish species, could successfully become dominant. Finally, the deployment of the ADP appears to provide a practical alternative for effective fishery resources management to improve species diversity and fish communities in an artificial freshwater ecosystem (garden pond, park pond, other artificial wetlands, etc.).

This research aims to build physics tools of measurement of river flow is current. The tool was developed with the balance spring as a means of collecting the data. data measurement results then analysed mathematically. It is designed using chloride polyvinyl (PVC) which is waterproof. The result of the test tool shows the average error value of 0.3342% and the value of the standard deviation of 0.1893. So, it can be stated that RAV current meter has a level of accuracy and the level of accuracy that is high enough. This equipment still needs to be optimized by performing test audiences to see the ease of the user. In addition. the size of the adjustment to the attention of the research further.
