Molluscicidal activity of tobacco dust against brackishwater pond snails (Cerithidea cingulata Gmelin)
(Elsevier, 1998)
Toxicity tests on the effect of tobacco dust against brackishwater pond snails (Cerithidea cingulata Gmelin) of various stages or size ranges were conducted under controlled laboratory conditions. The 72-h LC<sub>50</sub> ...
Enrichment of live food with essential fatty acids and vitamin C: effects on milkfish (Chanos chanos) larval performance
(Elsevier, 1998)
The effects of essential fatty acids (EFA) and vitamin C-enriched live food on growth, survival, resistance to salinity stress and incidence of deformity in milkfish larvae reared in tanks were investigated. Larvae were ...
Nature's subsidies to shrimp and salmon farming
(American Association for the Advancement of Science, 1998)
Although many fisheries stocks have declined precipitously throughout the world, fish farming--and especially shrimp and salmon farming--has boomed. The increasingly large scale of these enterprises is now having unforeseen ...
Sensitivity of fertilized milkfish (Chanos chanos Forsskal) eggs to mechanical shock and simulated transport
(Elsevier, 1998)
Naturally-spawned milkfish eggs are routinely subjected to physical manipulation during collection and transport. To avoid unnecessary mortalities, sensitivity of milkfish eggs to mechanical shock was determined at different ...
Use of metaldehyde as a molluscicide in semi-commercial and commercial milkfish ponds
(Elsevier, 1998)
The effect of metaldehyde on brackish water pond snails, Cerithidea cingulata, was tested in 250 m2 ponds, and in semi-commercial and commercial milkfish ponds. The field trials were conducted at three locations, namely ...
Fish farming in marine pens and cages in the Philippines: appropriate technology?
(Society of Aquaculture Engineers of the Philippines, Inc., 1998)
Contributed as Discussant in Technical Session 3 on Environmental Impacts of Marine Fishcage Farming, 12th Annual Meeting of the Society of Aquaculture Engineers of the Philippines, Inc. (SAEP), held at the BFAR-National ...
Growth and survival of milkfish (Chanos chanos), seabass (Lates calcarifer) and rabbitfish (Siganus guttatus) larvae reared at the same density in different sized tanks
(Society of Israeli Aquaculture and Marine Biotechnology, 1998)
Growth and survival of the larvae of milkfish (Chanos chanos), seabass (Lates calcarifer) and rabbitfish (Siganus guttatus) in 40, 200 and 500 liter rearing tanks were evaluated at day 14. Milkfish larvae survived better ...
Effect of salinity, dietary lipid source and level on growth of milkfish (Chanos chanos) fry
(Elsevier, 1998)
Six semi-purified microparticulate diets containing coconut oil (CO), cod liver oil (CLO), and their 1:1 combination (CO+CLO) at 9% and 18% levels were fed to milkfish fry or late postlarvae in freshwater (0 ‰), brackishwater ...
Milkfish (Chanos chanos) production and water quality in brackishwater ponds at different feeding levels and frequencies
(Wiley-Blackwell, 1998)
This study evaluated the effects of different feeding levels and frequencies on milkfish (Chanos chanos) growth, feed efficiency, and water quality in brackish water ponds. Milkfish juveniles (average weight, 1 g) were ...
The sulfide tolerance of milkfish and tilapia in relation to fish kills in farms and natural waters in the Philippines
(Kluwer Academic Publisher, 1998)
Fish kills of milkfish Chanos chanos and tilapia Oreochromis spp. now occur frequently in brackish, marine, and freshwater farms (ponds, pens, and cages) in the Philippines. Aquafarms with high organic load, limited water ...
