Screening of inexpensive and indigeneous ingredients for use in practical feed for juvile sea bass (Lates calcarifer Bloch)
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
An eight-week feeding experiment with juvenile sea bass (about 15 g) was conducted in 500-1 fiberglass tanks to screen the most cost-effective practical diet for use in ponds and floating cages. Eleven formulations and one ...
In vitro digestibility of locally available feedstuffs for white shrimp Penaeus indicus
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
An in vitro method of determining protein digestibility was modified for application in white shrimps. The protein digestibility of 21 locally available feedstuffs were determined. Vitamin-free casein was used as reference ...
Development of artificial diets for milkfish (Chanos chanos) larvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
This study aims to develop nutritionally balanced and cost-effective artificial diets for milkfish larvae. Two larval diets (Feed A and Feed B) were formulated and prepared to contain 45% protein and 10% lipid. Several ...
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 ...
The effect of different levels of vitamins premix in the diet of African catfish (Clarias gariepinus) fingerlings
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)
The present study was conducted to determine the growth and survival of African catfish (Clarias gariepinus) fingerlings fed diets with various levels of vitamin premix. The fingerlings (mean weight, 1.55 to 2.12 g) were ...
