Colour preference and colour vision of the larvae of the giant freshwater prawn Macrobrachium rosenbergii
- Journal of Experimental Marine Biology and Ecology, 2016 - Elsevier
This paper reports on the innate colour preference and colour vision in the hatchery-reared larvae (10–16 days old, stages IV–VIII) of the giant freshwater prawn Macrobrachium rosenbergii (De Man) based on their response ...
Low pH affects survival, growth, size distribution, and carapace quality of the postlarvae and early juveniles of the freshwater prawn Macrobrachium rosenbergii de Man
- Ocean Science Journal, 2015 - Springer Verlag
Acidification of rain water caused by air pollutants is now recognized as a serious threat to aquatic ecosystems. We examined the effects of low pH (control pH 7.5, pH 6, pH 5, pH 4) on the survival, growth, and shell ...
Effect of colored light regimes on the stress response and RNA/DNA ratio of juvenile red sea bream, Pagrus major
- Borneo Journal of Marine Science and Aquaculture, 2017 - Borneo Marine Research Institute, Universiti Malaysia Sabah
We hypothesized that fish with red-sensitive retina would be stressed by red light and thus inhibited in somatic growth. Red sea bream (Pagrus major) juveniles (total length =3 cm) with red-sensitive retina were chosen to ...
Sulfide as an environmental factor and toxicant: tolerance and adaptations in aquatic organisms
- Aquatic Toxicology, 1992 - Elsevier
This review brings together a large number of independent and seemingly unrelated studies in various disciplines under four major topics: (1) sulfide as an environmental factor in aquatic habitats; (2) sulfide as a toxicant; ...

- UPV Journal of Natural Sciences, 1997 - University of Philippines in the Visayas
This paper reviews the history and status of the milkfish fry fishery and hatchery and examines the issue of fry shortage in some detail. The fry fishery in the Philippines is a well developed industry that uses efficient ...
Weaning of hatchery-bred milkfish larvae from live food to artificial diets
- Aquaculture, 1984 - Elsevier
Two-week old milkfish (Chanos chanos ) larvae (7.5 mm standard length, 2.3 mg wet body weight) previously fed only rotifers were weaned abruptly to six artificial diets (commercial feed TP, artificial plankton AS and BP, ...
Shelter colour preference of the postlarvae of the giant freshwater prawn Macrobrachium rosenbergii
- Fisheries Science, 2017 - Springer Verlag
The addition of artificial shelters of various materials has been used in Macrobrachium rosenbergii tanks and ponds as a means of increasing productivity. The present study investigated the shelter colour preference of M. ...
