Site selection, structural design, construction, management and production of floating cage culture system in Malaysia
(Aquaculture Department, Southeast Asian Fisheries Development Center; International Development Research Centre, 1979)The success of cage culture system is largely determined by correct selection of favourable sites, suitable cage size and facilities and management of the system. These three elements are considered in this paper in relation to culture systems in Malaysia. -
The European and Hungarian results of cage culture of fish

The use of aquatic plants as feed for Tilapia nilotica in floating cages
(Aquaculture Department, Southeast Asian Fisheries Development Center; International Development Research Centre, 1979)Three kinds of aquatic plants, namely, Hydrilla verticillata, Lemna minor , and Chara sp. were used as feed for the T. nilotica reared in floating cages at three levels of stocking densities: 5, 15, and 45 fishes per cage. Results of the study showed that Lemna minor gave the best effect on growth rate of the fish in every level of stocking density. Feed conversion rate ranged from 19 to 33; Lemna minor was the lowest (33:1), while Chara sp. was the highest (19:1). -
Prospects of fish farming in cages in Karnafuli reservoir (Bangladesh)
(Aquaculture Department, Southeast Asian Fisheries Development Center; International Development Research Centre, 1979)The Karnafuli Reservoir (Kaptai Lake) has immense prospects for aquaculture as shown by recent limnological and biological studies. It is therefore expected that fish cages culture will become a booming industry in Karnafuli Reservoir. -
Net cage culture of Lates calcarifer Bloch and other marine animals in Thailand
(Aquaculture Department, Southeast Asian Fisheries Development Center; International Development Research Centre, 1979)Feeding experiments on sea bass, Lates calcaifer , have been carried out in nylon net cages in Songkhla, since 1971, to obtain information on: (1) growth rates; (2) survival rates; (3) food conversion rates; (4) environmental conditions that affect the fish. Data from these experiments, some of which are briefly reproduced in this paper, prove that sea bass can be successfully cultured in net cage. Among other marine invertebrates, the cuttle fish, Sepia sp., showed the best potential for culture in net cage. -
Prospects of developing cage and pen culture in Sudan
(Aquaculture Department, Southeast Asian Fisheries Development Center; International Development Research Centre, 1979)This paper describes the prospects of cage and pen culture in Sudan and recommends that a project for developing pen and cage culture techniques be started for marine and freshwater aquaculture. -
Development of circular floating cages for milkfish broodstock at the SEAFDEC Aquaculture Department
(Aquaculture Department, Southeast Asian Fisheries Development Center; International Development Research Centre, 1979)The present attempt to develop floating cages for holding milkfish, Chanos chanos, broodstock at SEAFDEC was prompted by the need of the department to have more fish for experimentation. This paper briefly presents the departments experience in developing the cage culture system designed for holding milkfish for broodstock purposes. The following points are discussed: (1) site location; (2) biological factors; (3) floats; (4) netting; (5) framework; (6) layout and mooring; (7) maintenance; (8) cost. Designs are given for the net cage cover, frame and floats. -
Isolation, identification of causative agent of "red boil disease" in grouper (Epinephelus salmoides) and its possible control by vaccination
(Aquaculture Department, Southeast Asian Fisheries Development Center; International Development Research Centre, 1979)This report presents the initial results of studies on the isolation and identification of the causative agent as well as possible immunization of the estuary groupers. It is hoped that by a vaccination programme, fish could be made immune to such disease. Results indicate: (1) Vibrio parahaemolyticus is pathogenic to estuary grouper (2) that the vaccines did not seem to protect the fish against the vibrio when challenged one week after vaccination, but that this was due to slow antibody production of the fish as salmonids challenged about 30-35 days after vaccination reported good protection against Vibrio anguillarum and other bacterial diseases. Experiments are now in progress to challenge the vaccinated groupers at a later stage. -
Fish cage culture in the town of Jambi, Indonesia
(Aquaculture Department, Southeast Asian Fisheries Development Center; International Development Research Centre, 1979)This paper discusses the floating cage fish culture in Jambi, its present status and its constraints to further development. The report is based mainly on interviews with fish farmers. To accelerate further development, a series of research programmes related to floating cage fish culture is recommended. -
Experiments on raising quality fish seed in floating nurseries and its role in aquaculture in India
(Aquaculture Department, Southeast Asian Fisheries Development Center; International Development Research Centre, 1979)Observations on experiments carried out on raising quality fish seed in floating nurseries and raising fish of marketable size in cages at Allahabad are reported. The experiments proved successful in terms of (1) rearing carp spawn to fry stages; (2) rearing carp fry in floating nurseries (cages) in lentic waters to fingerling stage. -

Common carp in floating net cage culture
(Aquaculture Department, Southeast Asian Fisheries Development Center; International Development Research Centre, 1979)The main objective of this experiment was to determine the optimal density or stocking rate for the optimal total production and growth rate of common carp, Cyprinus carpio . A raft of 10 x 10 m made of steel bars with drums as floaters was divided into nine plots. A cage of polyethylene 3 x 3 x 2 m, 1 inch mesh size was hung in every plot. About three fourths of the cage was under water. Three stages of stocking rate of common carp of about 130 g individual weight were used: 2 kg/m2, 4 kg/m2 and 6 kg/m2. The experimental Latin Square design was used. Artificial fish food (pellet) containing about 32 percent crude protein was given five times a day. Fish were fed to satiation. Morphometrical and limnological data were measured every 14 days. Individual growth and actual rations were calculated daily. As a result of this experiment, common carp culture is floating net cages with a stocking rate of 6 kg/m2 is recommended. -
