Morphological measurements, gonadal development and estimated age of adult milkfish, Chanos chanos captured in Pandan Bay from 10 May - 16 June, 1975

From 10 May to 16 June, 1975, 106 adult milkfish were captured in an otoshi-ami 500 meters offshore. Of the 106 specimens, 37 were females in various stages of gonadal development or spent and 69 were males of which 41 were sexually mature. The age of these fishes were estimated to be between 3 and 5 years

Spawning of milkfish, Chanos chanos, in captivity

Newly captured milkfish released 0.8 mm in diameter non-hydrated eggs spontaneously in captivity. After injection with partially purified salmon gonadotropin (SG-G100), 1.2 mm in diameter hydrated eggs were released. These eggs, however, were not fertilized

The occurrence of milkfish Chanos chanos fry in Pandan Bay, Antique, from 21 May to 25 June, 1975

Milkfish fry were collected at the Pandan shoreline and 500 meters offshore. While shore-caught fry were uniform in size those captured offshore varied in size and stage of development
