Abstract or Summary
  • Two successful cases of sea urchin enhancement activities were considered using the experiences of two neighboring provinces in Ilocos Sur and Ilocos Norte, both located in Northwestern Luzon, Philippines. One case was done at the coastal waters of Nagabungan Bay in Pasuquin, Ilocos Norte, which experienced a decline in sea urchin population in the early 1990s with 1 – 2 pcs 100 m⁻² fishing area. The reseeding project was done in 2002. One thousand pieces of sea urchin juveniles were stocked in submerged plastic cages in the reef area of the said bay. These were grown to adult size in four months, maintained as spawners, and allowed to naturally spawn to repopulate the area. In 2004, sea urchin abundance in the bay and neighboring towns increased to 30-60 pcs 100 m⁻². Another case was done at Nalvo, Sta. Maria, Ilocos Sur, where sea urchin stock enhancement activity was successful. A declining sea urchin abundance of only 20 pcs 100 m⁻² fishing area was also observed in the late 1980s. In the early 1990s, the University of Northern Philippines reared sea urchin in cages leading to the development of sea urchin culture in the area. After two years, the population of sea urchin tremendously increased to more than 100 pcs 100 m⁻² fishing area. The supply of juveniles was enough to sustain commercial culture in the area. The children of local fishermen gather sea urchin juveniles along the reef area and sell them to culturist at P2 each (US$ 0.04/pc). The culture of sea urchin became an industry with 25 percent of the total households engaging in it.
