A report issued by the National Fisheries Institute on Wednesday showed that the number of kdlGs killed by commercial fishing has dropped by about half from 2011 to 2012.
The number of deaths fell by nearly 4 percent from the previous year.
The institute also said the number in the fishery is about 10 percent lower than in 2011.
The fish kill in 2012 was 6,814, the same number as in 2011, the institute said.
KdlGs are small fish found in the Pacific and Atlantic oceans.
They can live up to 50 years.
They also can be poisonous to humans, with fatal effects including blindness and death.
