Investigations on the feeding behavior of juvenile milkfish (Chanos chanos Forsskål) in brackishwater lagoons on South Tarawa, Kiribati
wfish.de Abstract
This study evaluated the feeding behavior of the milkfish (Chanos chanos Forsskål) in extensively managed brackishwater lagoons on South Tarawa, Kiribati (Central Pacific) in August 1998. Feed intake, dietary overlap, fish condition and morphometric intestine parameters were determined. The daily ration of fish was estimated using the ”modified Bajkov model”. Fish stomach content did not differ significantly between samples from day and night, but prey preferences showed significant differences (p < 0.05). Results were compared with a data set of juvenile milkfish from the Philippines raised under similar conditions.

Effects of salinity on growth of young milkfish, Chanos chanos
- In Proceedings of the International Milkfish Workshop Conference, May 19-22, 1976, Tigbauan, Iloilo, Philippines, 1976 - Aquaculture Department, Southeast Asian Fisheries Development CenterGrowth of young milkfish was studied at different levels of salinity over a period 68 days. Results suggested that young milkfish reared in freshwater or less saline sea water grew faster than in sea water. The increase in body weight was neither due to the increase in water content nor increase in feeding rate. The difference in growth rate might be attributed to the deviation from the original acclimating salinity. Mechanisms of the effect of salinity in retarding or accelerating milkfish growth should be investigated in the future. -

Morphological measurements, gonadal development and estimated age of adult milkfish, Chanos chanos captured in Pandan Bay from 10 May - 16 June, 1975
- In Proceedings of the International Milkfish Workshop Conference, May 19-22, 1976, Tigbauan, Iloilo, Philippines, 1976 - Aquaculture Department, Southeast Asian Fisheries Development CenterFrom 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. -

Preliminary observation on the number of vertebra in milkfish, Chanos chanos (Forskal)
- In Proceedings of the International Milkfish Workshop Conference, May 19-22, 1976, Tigbauan, Iloilo, Philippines, 1976 - Aquaculture Department, Southeast Asian Fisheries Development CenterThe existence of races and/or subpopulation in milkfish, a widely distributed species, is suggested by many workers. Comparison of mean numbers of vertebrae is one of the useful method of distinguishing subpopulations. The present paper reports the results of preliminary studies made on the vertebral counts of milkfish fry collected from several areas. The results obtained, though not conclusive, suggest the scope for further study in the line.
