A preliminary study on the diagnosis of coral reef healthiness and establishment of coral replenishment technology
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2015)Field surveys for coral reef through line-intercept-transect (LIT) and temperature profiling using data-loggers were done at three layers of 5, 10, and 15 m depths in coral reef areas, Nogas Island, Anini-y, Antique, ... -
Preliminary trials on the effects of weaning and larval diets on survival and growth of silver therapon (Leiopotherapon plumbeus) larvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2015)Success in larval rearing of silver therapon can be achieved through early weaning of fish larvae from live food to artificial diet. Two experiments were carried out to investigate the effects of (a) weaning age (abrupt ... -
Preliminary trials on the optimization of hormone dosages for induced breeding of Philippine silver perch, Leiopotherapon plumbeus
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2015)The silver perch Leiopotherapon plumbeus, locally known as ayungin, is an endemic freshwater fish that is commercially valuable as it commands a high price in the local market. Due to excessive fishing and other potential ... -
Rapid adaptation to a new environment: is it reversible?
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2015)Accumulating evidence suggests rapid adaptation of fish populations when they are exposed to artificial hatchery environments. However, little is known if rapidly-adapted populations can readapt to their original, natural ... -
