FREQUENT MONITORING OF WATER TEMPERATURE IN PEGAMETAN BAY, BALI: A PRELIMINARY ASSESSMENT TOWARDS MANAGEMENT OF MARINE AQUACULTURE DEVELOPMENT
Abstract: Aquaculture
currently share for nearly half of the world’s food fish consumption, and
continue to be the fastest-growing animal food producing sector. The viability
of aquaculture operation has greatly been affected by the characteristic of
marine environment. Inventory and monitoring of marine environment are
necessary and can be done through information technology implementation.
Frequent monitoring of water temperature, for almost one year observation, at
four aquaculture sites in Pegametan Bay and Research and Development Institute
for Mariculture was investigated. Water temperature data were obtained by using
logger and buoy systems. These data were contrasted against marine fish
mortality. On the other hand, the suitability of species requirements with the
thermal conditions was evaluated by comparing temperature range to the optimum
and lethal temperature information available on marine fish species of
aquaculture interest. This research could be beneficial for enhancing
productivity of marine aquaculture operation in terms of possible impact of
climate change. It was also possible to find the ideal temperature range for
culturing fish species, taking into account the variability associated with
large-scale phenomena.
