Abstract
Trichodiniasis was noted in an intensive milkfish (Chanos chanos) nursery pond in Dumangas, Iloilo, Philippines. It was predominantly caused by a small trichodinid species (body diameter=23-29 µm) with well-developed denticles, identified as Paratrichodina sp. The trichodinid infection resulted in proliferative changes, including clubbing and epithelial hyperplasis of the gill lamellae sufficient to disrupt respiratory function. Tolerance tests of milkfish fingerlings in an earthen pond-simulated environment resulted in a 24 h TL90 value of 1.98 ± 0.25 ppm KMnO4. A treatment of 1.0 ppm KMnO4 was highly efficacious (96%) in eliminating trichodinids on gills with minimal mortality of treated milkfish observed 24 hours post-treatment.

The modular method: Milkfish pond culture
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1999)The modular method of milkfish culture (Chanos chanos) described in the manual is an improvement over the traditional extensive method. The manual is intended for the use of fish farmers and aquaculturists, extensionists, and students of aquaculture not only in the Philippines, but also in other milkfish-producing countries in Southeast Asia and the world. It covers the following: Interesting facts about milkfish -- biological characteristics, artificial breeding of milkfish; Design and operation of modular pond system -- pond preparation, stocking in the nursery or transition ponds, stocking in the rearing ponds, care of stock, pond utilization and production schedule, harvest and post-harvest; and, Economics and costing. -
Evaluation of organic and inorganic fertilizers in brackishwater milkfish ponds
(Elsevier, 1989)The study was conducted in twelve 144-m2 ponds to evaluate the effect of different organic and inorganic fertilizers on the growth, survival, gross production, and profitability of marketable milkfish. The following treatments were used: Treatment I, SEAFDEC traditional fertilization practice (16-20-0 at 50 kg/ha and 45-0-0 at 15 kg/ha); Treatment II, half-dosage of Treatment I; Treatment III, chicken manure at 0.5 ton/ha; and Treatment IV, MASA (processed from agricultural and industrial wastes) fertilizer at 0.5 ton/ha. All treatments were applied once in every 2 weeks. No significant difference (P > 0.05) existed in the harvest and production of milkfish among the treatments. However, economic indicators such as return-on-investment (ROI), payback period, and marginal analysis ranked the performance of the fertilizer treatments in the order of I, II, III and IV. Fish kills occurred in three ponds applied with chicken manure and MASA fertilizer. This could have been due to a heavy build-up of organic matter in the pond bottom which led to the collapse of the benthic algal community, depletion of dissolved oxygen and the presence of hydrogen sulfide. It is therefore suggested that a lower dosage of organic fertilizer should be applied in ponds especially during the rainy season. -
Milkfish breeding and hatchery technology at SEAFDEC/AQD
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1999)Describes the techniques already adopted by the private sector: broodstock management, broodstock diet, commercial fry production, live transport, and larval diet. A list of AQD research publications on milkfish is included.
