Successful use of cryopreserved oyster trocophores as a live first feed larval marine fish and invertebrates
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Trochophore-stage larvae of the Pacific oyster Crassostrea gigas were cryopreserved in bulk and stored in liquid nitrogen for periods up to two years before thawing and feeding to a variety of warmwater and coldwater larval ...
Algal production and utilization relevant to aquaculture in the Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1990)
An outline is given of research conducted at the Aquaculture Department of SEAFDEC at Rizal, Philippines regarding algal culture and utilization. Culture methods for both brackishwater and freshwater algae are described ...
A review of SEAFDEC/AQD finfish breeding research
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Recent progress undertaken by SEAFDEC/AQD in the development of broodstock of a variety of cultured fish in the Philippines is reviewed. Spontaneous maturation and spawning has been achieved among captive breeders of ...
Milkfish, rabbitfish and mullet
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1994)
This paper reviews studies conducted on milkfish (Chanos chanos), rabbitfish (Siganus guttatus), and mullet (Mugil cephalus) at the SEAFDEC Aquaculture Department from 1968 to 1991. Milkfish studies focused on hormonal ...
Feed quality problems and management strategies
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Feed is the single most important input in increasing aquaculture production and profits. Success or failure in augmenting yield with feeding depends, to a large extent, on the quality of the diet. Feed quality, generally ...
Effect of a diet lacking in vitamin and mineral supplements on the growth and survival of Penaeus monodon juveniles in a modified extensive culture system
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Penaeus monodon juveniles (mean weight, 0.006 g) were reared in 330 m earthen ponds for 120 days at a stocking density of 7.5/m2 under conditions of the modified extensive system of culturing shrimps. The shrimps were fed ...
L-ascorbyl-2-phosphate Mg as vitamin C source for juvenile Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Phosphated ascorbic acid (magnesium L-ascorbyl-2-phosphate or MAP) is a stable form of vitamin C. The suitability and growth requirement level of this derivative in practical diet was determined for juvenile Penaeus monodon. ...
Farm-made feeds: preparation, management, problems, and recommendations
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Making feeds exclusively for certain farming activities is quite common in the tropics particularly in the farming of fishes that feed low in the food chain. Feed preparation will depend on several factors such as availability ...
Effect of dietary astaxanthin and vitamin A on the reproductive performance of Penaeus monodon broodstock
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Reproductive performance of pond-reared tiger shrimp given astaxanthin (100 mg/kg diet) and Vitamin A (20,000 IU) for 61 days was assessed in a 2x2 factorial experiment in a completely randomized design. Mean gonad index ...
Feed formulation and evaluation for semi-intensive culture of fishes and shrimps in the tropics
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
Semi-intensive farming systems account for about 70% of fish and crustacean aquaculture production in the tropics, employing semi-intensive feeding methods ranging from the use of low-cost pond fertilization techniques to ...
