Utilization of sensors and SMS technology to remotely maintain the level of dissolved oxygen, salinity and temperature of fishponds
MunozRC2015.pdf (265.7Kb)Abstract
Due to the occurrence of fish kills in various fish producing areas in our country, millions of pesos and opportunities for the Filipino people had been put into waste. Bataan Peninsula State University (BPSU) collaborated with the Central Luzon Association of Small-scale Aquaculture to devise strategies to address the said problem and prevent further losses.
More often than not, a fish kill can be attributed to the low level of dissolved oxygen (DO) in the water, decrease or increase in salinity and sudden increase in temperature, which usually occur after heavy rainfall, flooding or high tide, or high levels of ammonia due to decomposing organic matter and high temperature during summer.
For these reasons, BPSU researchers tested the use of radio frequencies and installed sensors in different areas of the fishpond at various depths to remotely monitor the levels of DO, salinity and temperature of the water. Once these reach critical levels, the installed system which comes with a specific program, will send an alarm through radio frequencies via Short Messaging Services (SMS) technology on the cellular/mobile phone of the caretaker or the fishpond operator. Upon receiving the alarm, caretakers were able to adjust the levels of dissolved oxygen, salinity and temperature of the water by remotely switching on the air compressor or the electric water pump using their cellular/ mobile phone, thus preventing losses due to fish kills.

Polyculture of milkfish Chanos chanos (Forsskal) and the red seaweed Gracilariopsis bailinae (Zhang et Xia) in brackish water earthen ponds
-Aquaculture Research , 2004 - Wiley-BlackwellGrowth, net production, and survival rates of milkfish cultured with Gracilariopsis bailinae at two stocking density combinations (T1– 30 fingerlings 100-m−2 pond+1-kg G. bailinae 4-m−2 net cage, T2– 30 fingerlings 100-m−2 pond+2-kg G. bailinae 4-m−2 net cage) in brackish water earthen ponds over four culture periods were determined. The control (T3) was stocked at 30 fingerlings 100-m−2 pond. Specific growth and production rates of G. bailinae were also calculated. There were no significant differences in mean growth, survival, and net production rates of milkfish between the three treatments. Irrespective of stocking singly or in combination with G. bailinae, significantly higher mean growth and mean production rates for milkfish were obtained during the third culture period of year 1 than those obtained from the other culture periods. Survival rates were not significantly different among the four culture periods. There were no significant differences in mean specific growth and mean net production rates between the two stocking densities of G. bailinae. Significantly higher mean specific growth and mean net production rates of red seaweed were also obtained during the third culture period of year 1 than those obtained from other culture periods. The production of milkfish and red seaweed was higher during the dry season. Growth rates of milkfish was positively correlated with temperature and salinity, while net production rates were positively correlated with temperature and total rainfall, but was inversely correlated with dissolved oxygen. G. bailinae growth and net production rates were positively correlated with water temperature and salinity. Results show that milkfish can be polycultured with G. bailinae grown in net cages in brackish water ponds at stocking density combination of 30 fingerlings 100-m−2 pond+1-kg G. bailinae 4-m−2 net cage. -

Survival and settlement rates of Haliotis asinina larvae at different salinity levels
-IAMURE International Journal of Ecology and Conservation , 2013 - IAMURE Multidisciplinary ResearchThe study was conducted to determine the optimum salinity levels (24 ppt, 28 ppt, 32 ppt, 36 ppt and 40 ppt) for the survival and settlement rates of H. asinina in a complete randomized design with three replicates each. The experimental animals were reared in 15 glass aquaria for the first run and in plexiglass for the second run. Feeding of Navicula spp. was done once a day. Temperature and dissolved oxygen were monitored throughout the experiment. Data were analyzed using One-Way ANOVA to determine significant difference among treatments at 0.05 level of significance using Social Package for Social Science. Result of the first run showed that 32 ppt had the highest mean survival (1.50%) and mean settlement rate (1.84%). Similar result was also observed in 32 ppt with highest mean survival (9.72%) and mean settlement rate (16.42%). Significant difference existed among treatments during the second run of the experiment. Results showed that 28 ppt and 32 ppt were the optimum salinity levels for survival and settlement rate of H. asinina. Further study should be conducted to determine the tolerance and settlement rates of H. asinina larvae to lower salinities until it reaches juvenile stage with first respiratory pore appearing. -

Parameters in site selection and monitoring
- In Training Handbook on Rural Aquaculture, 2009 - Aquaculture Department, Southeast Asian Fisheries Development CenterBefore starting an aquaculture venture, it is necessary to first select an appropriate project site. Doing this ensures that money invested in the project is not later wasted because the site does not meet the requirements of the culture organism. It also makes sure that the environment is not compromised and will be able to sustain the aquaculture activities. Two major parameters are considered during site selection. These are the 1) physico-chemical; and 2) environmental parameters. Physico-chemical parameters affect the health of the culture organisms while the environmental parameters will give insights on the sustainability of the aquaculture venture. However, the task does not end with site selection. Monitoring of the aquatic environments is also essential to note any changes in the environment that may affect the aquaculture project and the environment itself.
