An even bigger burden was electricity: Deep-sea mollusks are best suited to live in waters of a temperature of 20 oC. Hence, Rumphius 'slit shells, common nautiluses, and cowries all require their own chillers. This necessitated another NT $ 200,000-plus outlay. And then there's the monthly NT $ 25,000 electricity bill.
更大的負擔是水電費用：深海貝類適合生存的溫度大約只有攝氏 20 度，包括龍宮貝、鸚鵡螺、寶螺，3 種飼養箱都需各自有一台冷卻機，這又花了張議顯二十多萬元，還有每個月約 2 萬 5,000 元的電費。
