The Reproductive Aspect of Tropical Abalone (Haliotis asinina L.) in the Waters of Tanakeke Islands at South Sulawesi

Abalone (Haliotis asinina) is a mollusk species that belonged to gastropode/snail class. It was identified by its shape of ear, and thus, it was called as ‘donkey ear’. This abalone was a popular export commodity. It was favorite food among people in other countries such as Japan, United States, Europe Countries, Columbia and Canada. Because its delicious meat. Indeed, 100 grams abalone meat contained 83 calories, 59 mg cholesterol, 0.1 g lipid, 2.7 g carbohydrate, and vitamins B1, B2, B6 and B12, as well as some minerals such as calcium, iron, zinc, magnesium and selenium.

Market demand was high, and therefore, abalone was continually exploited and subjected to the reduction of population (Maliao et al., 2004). The preservation of abalone resources must need management actions, including the management of hauling, the closure of hauling region and season, the limitation of work quantity and hauling outcome, or the prevail of quota system (Rounsefell, 1975, Gulland, 1977). However, cultivation was a solution that was recently coming into consideration.

Abalone cultivation was always possible if the seed was available in constant. To obtain the seed in constant, thus, seeding was needed. However, a main problem in abalone seeding was lack of availability of local prime. A location that was expected to become the producer of local abalone prime was Tanakeke Islands, an island cluster in the Spermonde Islands. Tanakeke was, in fact, abalone hauling site. Coral reefs were surrounding the island (Yunus, 2009).

One of the problems in the abalone hatchery has been the availability of a local broodstock. Therefore, information about the existence and potential of the local broodstock that can be as the source of the broodstock for purposes of abalone hatchery in South Sulawesi. Review on the reproductive biological aspect, thus, should be very important.
