Behavioural evidence for colour vision determined by conditioning in the purple mud crab Scylla tranquebarica
Kawamura, Gunzo; Bagarinao, Teodora ; Cheah, Hue Sin; Saito, Hiroaki; Yong, Annita Seok Kian; Lim, Leong-Seng (Springer Verlag, 2020-01-04)Crabs and shrimps (order Decapoda) use colours in various tasks such as foraging and mate choice. Colour vision requires at least two types of photoreceptors with different spectral sensitivities. Previous physiological ... -
Biodiversity in mangrove-derived aquaculture ponds in Dumangas, Iloilo, Philippines
Bagarinao, Teodora (Science and Technology Information Institute, Department of Science and Technology, 2021-02)Large tracts of mangroves have been converted into aquaculture ponds and the consequent loss of biodiversity has been much decried. This paper shows that high aquatic biodiversity is retained in mangrove-derived aquaculture ... -
Colour discrimination in dim light by the larvae of the African catfish Clarias gariepinus
Kawamura, Gunzo; Bagarinao, Teodora ; Hoo, Patt Kar; Justin, Joanevieve; Lim, Leong Seng (Springer, 2017)Many demersal fish species undergo vertical shifts in habitats during ontogeny especially after larval metamorphosis. The visual spectral sensitivity shifts with the habitat, indicating a change in colour vision. Colour ... -
Colour preference and colour vision of the larvae of the giant freshwater prawn Macrobrachium rosenbergii
Kawamura, Gunzo; Bagarinao, Teodora ; Yong, Annita Seok Kian; Jeganathan, Ivy Michelle Xavier; Lim, Leong-Seng (Elsevier, 2016)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 ... -
Early appearance of the retinal tapetum, cones, and rods in the larvae of the African catfish Clarias gariepinus
In the retina of the African catfish Clarias gariepinus, the pigment epithelium and the tapetum were formed in newly hatched larvae, the cones developed within 2 days, and the rods within 3 days after hatching. The retinal ... -
Early ossification and development of the cranium and paired girdles of Chanos chanos (Teleostei, Gonorynchiformes)
In this chapter, we provide new data on the timing of ossification of cranial and paired girdle elements, and compare our results, when it is possible, with previous work on early ossification development of Chanos chanos. ... -
Ecological considerations in milkfish farming in marine pens and cages in the Philippines
Milkfish farming in the Philippines has a long history and great importance, being widely regarded as the way to domestic food security. But the industry has faced new challenges in the past decade, with the advent of many ... -
Effect of colored light regimes on the stress response and RNA/DNA ratio of juvenile red sea bream, Pagrus major
Kawamura, Gunzo; Bagarinao, Teodora ; Anraku, Kazuhiko; Okamoto, Masaru (Borneo Marine Research Institute, Universiti Malaysia Sabah, 2017)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 ... -
Egg size and larval size among teleosts: implications to survival potential
A survey of the early life history characteristics of 135 teleost fishes from freshwater, marine, tropical, temperate and boreal habitats show the influence of egg size and larval size on survival potential. Marine species ... -
Feeding habits of larval rabbitfish, Siganus guttatus in the laboratory
Hara, S.; Kohno, H.; Duray, Marietta; Bagarinao, Teodora ; Gallego, A.; Taki, Y. (Asian Fisheries Society, 1986)The feeding habits of Siganus guttatus larvae were determined in laboratory rearing studies at 23.8-30.3 degree C by examination of digestive tract contents of larvae given rotifers and/or brine shrimp. Larvae were initially ... -
The filter net [tangab] fishery in Iloilo Strait, Philippines: Food and livelihood for coastal communities in the midst of waste of non-target fishery resources
The Philippines is home to a mixed of blessings: an enormous marine biodiversity, a tremendous variety of fishery enterprises, and about 50 million coastal residents who mostly fish and eat fish. So many animals and so ... -
Fish behaviour and aquaculture
Research in the application of fundamental concepts of fish behaviour to aquaculture has intensified recently and this chapter further elucidates fish sensory systems and functions and their involvement in the success or ... -
Fish farming in marine pens and cages in the Philippines: appropriate technology?
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 ... -
Fish habitats in a small, human-impacted Sibunag mangrove creek (Guimaras, Philippines): a basis for mangrove resource enhancement
The fish assemblage of a small, open access mangrove creek highly influenced by aquaculture farms, was studied for the first time in the Philippines as a baseline of such system as well as examining the degree of ecological ... -
Fishing methods and gears in Panay Island, Philippines
The authors surveyed the fishing methods and gears in Panay and smaller neighboring islands in the Philippines in September-December 1979 and in March-May 1980. This paper is a report on the fishing methods and gears used ... -
Food colour preference of hatchery-reared juveniles of African catfish Clarias gariepinus
Food colour preference is a fundamental aspect of food recognition and has practical application in the formulation of artificial diets and the design of visual baits. Food colour affects growth performance and feed ... -
From triphenyltins to integrated management of the 'pest' snail Cerithidea cingulata in mangrove-derived milkfish ponds in the Philippines
The potamidid snail Cerithidea cingulata is considered a pest in brackishwater milkfish ponds in the Philippines and has been controlled by the triphenyltin (TPT) compounds Aquatin and Brestan. But TPT is also toxic to ... -
A fundamental study on the behavior of milkfish fry for improving the efficiency of traditional fry collecting gear in the Philippines
Kawamura, Gunzo; Hara, Shiro; Bagarinao, Teodora (Kagoshima University Research Center for the South Pacific, 1980)The reaction of milkfish fry to miving and stationary nets of different meshes and colors in an experimental tank was determined. The underwater visibility of the nets saw measured and the water filtration in a fry-sweeper ... -
