Ancient fish species discovered in Biak

Biak (ANTARA News) - Biak Regent Yusuf Melianus Maryen has stated that a Japanese researcher recently reported sightings of Kolakan, a prehistoric fish species, in the waters off Oparief village, Biak Numfor district, Papua province.

"This large-sized ancient fish, which has existed since prehistoric times but was thought to have disappeared hundreds of years ago, can still be found in Oparief waters," he said here on Tuesday.

Yusuf expressed hope that the habitat of Kolakan fish would be preserved so it could attract foreign tourists.

He praised the Japanese researcher for identifying the area as a potential habitat of the Kolakan fish.

"Ancient fish habitat can be an excellent attraction for foreign tourists and it can support the marine tourism sector in Biak, which offers diving, fishing and snorkelling opportunities," Yusuf said.

He noted that regional revenue from tourism was limited due to a lack of investors in the sector.

"However, the local administration has put in place the necessary regulations to preserve the natural resources around Biak Island, in an effort to boost the local economy," Yusuf explained.

According to official data, some 15,000 tourists "both local and international" visit Biak Numfor annually.

Abstract

Releasing aquarium-held sharks when no longer needed by the holding institution may help mitigate the impacts that
aquaria have on declining wild populations. To investigate the viability of releasing display specimens, four raggedtooth sharks (Carcharias taurus) that had been held at Two Oceans Aquarium, Cape Town were released back to the wild between 2004 and 2008. To test the hypothesis that they survived and that their movement patterns were similar to wild conspecifics, wild-caught sharks were also tagged and released at the same time and locality. Aquarium- and wild-caught sharks were equipped with pop-up archival (PAT) tags, VEMCO ultrasonic tags, and numbered spaghetti dart tags. With the exception of one individual, all the aquarium-released sharks survived. Both aquarium-released and wild-captured sharks displayed eastward movements and travelled hundreds of kilometres after release. Data from the PAT tags indicated that individuals from both groups swam mainly in shallow waters, but dived as deep as 80 m to mid-shelf waters. A wide temperature tolerance was exhibited as they travelled though temperatures ranging from 10 to 22oC. Movement tracks of the sharks revealed ‘station keeping’ and an autumn migration between April and May. Rates of movement between individuals were variable. The depth range recorded in this study supports published information on habitat and prey choice. This study illustrates that this species can survive aquarium release after years of captivity and that they appear to behave similarly to wild-caught conspecifics.
