\nto monitor salmon during ocean migration

\nKINGSTON, R.I. — June 27, 2002 — When 溏心vlog免费B站 researcher Godi Fischer talks about fish and chips, food is the farthest thing from his mind. That\u2019s because he has developed a microelectronic chip that could play a key role in collecting data about the habitat salmon prefer during their two- to three-year ocean migration. <\/p>\n

\tThe device was developed because of concerns expressed by 溏心vlog免费B站 Fisheries Professor Conrad Recksiek that salmon mortality rates appear to be linked to increasing ocean temperatures caused by global warming. But, according to Recksiek, there was no reliable way to obtain the data to confirm his hypothesis. <\/p>\n

\tSo Fischer, a professor of electrical and computer engineering, and a group of students designed a temperature monitoring tag that could be implanted in the salmon. <\/p>\n

\t“The engineering challenge was in providing it with enough power to last for the two or three years that the fish are at sea,” Fischer said. “We also had to include all the necessary functions \u2013 the thermal sensor, data converter, memory, control circuitry and oscillator \u2013 all together on one tiny chip. No one had done that before.” <\/p>\n

\tThe device consists of a silicon chip measuring not more than 2.1 by 3.3 millimeters and a tiny battery that produces one micro-amp of electrical current, one million times less than that used by a standard light bulb. The chip is programmable, so temperature data can be collected as often as desired. <\/p>\n

\tA prototype of the device will be tested on salmon this year. The chips will be sealed in epoxy for durability and attached to the dorsal fin of each fish. Fischer and Recksiek are also experimenting with an internal version that might be safer for the fish. In addition, they\u2019re working on making the device inexpensive to manufacture, since thousands of fish must be tagged in order to retrieve enough of the tagged fish for the data to be statistically reliable. Retrieval rates are expected to be about 5 percent. <\/p>\n

\tSalmon spawn in the same river where they were born but spend most of their lifetime in the ocean. Biologists aren\u2019t certain exactly where in the ocean the fish travel and what habitat factors affect their survival rates. Fischer\u2019s temperature sensor will help to shed some light on this subject. <\/p>\n

\tWhile the electronic tag was developed for use in tracking fish, Fischer said it could also be used to record the temperature of goods that must be maintained at certain temperatures while they are transported around the world. “I\u2019m sure there are many more applications that we haven\u2019t even thought of yet,” added the Narragansett resident. <\/p>\n

\tNext up for Fischer is another fish monitoring device that collects data on salinity, water pressure, and precise location so additional information about salmon habitat preferences can be tracked. <\/p>\n

\tFunding for Fischer\u2019s research was provided by the Catalyst Foundation and the National Oceanic and Atmospheric Administration through its Cooperative Marine Education and Research program. <\/p>\n
