(Wiley, 2022-11-02)This study examined the performance and suitability of two tropical anguillid eels, Anguilla bicolor pacifica and A. marmorata, under cage culture conditions. Juvenile eels (1.73 ± 0.14 g body weight) of each ... -
Can Ulva reticulata replace Gracilariopsis heteroclada as natural food for the abalone Haliotis asinina?
(Springer, 2021-02-04)Abalone are among the most important fishery resources with high commercial values worldwide, with Haliotis asinina being the most in demand and widely studied species in the Philippines. Abalone culture in the country ... -
Carbohydrate requirements of Penaeus monodon (Fabricius) juveniles
(Elsevier, 1987)P. monodon juveniles with an initial mean weight of 0.62 g were fed isonitrogenous (45%) and isolipidic (10%) semi-purified diets containing 10, 20 and 30% trehalose, sucrose and glucose for 56 days. Shrimp fed the diet ... -
Carbohydrate, nitrogen and protein content of kinetin-treated Azolla pinnata var. imbricata plants.
(College of Arts and Sciences, University of the Philippines, 1988)The influence of various levels of kinetin on growth, carbohydrate, nitrogen, and protein content of Azolla pinnata var. imbricata plants cultured in a nitrogen-free 40% Hoagland’s solution under greenhouse conditions was ... -
Carpospore germination and early stages of development in Gracilaria edulis (Gmelin) Silva and Gracilaria rubra Chang et Xia (Gracilariales, Rhodophyta)
(San Carlos Publications, University of San Carlos, 1993)Carpospore germination and early stages of development in Gracilaria edulis and Gracilaria rubra of the Philippines are described for the first time. Both species follow the "Dumontia type" or the immediate discal type of ... -
Carrageenan properties and proximate composition of three morphotypes of Kappaphycus alvarezii Doty (Gigartinales, Rhodophyta) grown at two depths
(Walter de Gruyter, 1995)Three morphotypes (brown, green and red) of Kappaphycus alvarezii grown at two depths were evaluated for carrageenan properties and proximate composition. The green morphotype was significantly different from the brown and ... -
Cell growth and nutritive value of the tropical benthic diatom, Amphora sp., at varying levels of nutrients and light intensity, and different culture locations
(Springer Verlag, 2007)Two series of experiments were conducted to determine suitable growth factors for the mass propagation of the local algal isolate Amphora sp. A higher growth rate of 0.2 doubling (μ) day-1 was attained at a lower ... -
Cell growth, effect of filtrate and nutritive value of the tropical Prasinophyte Tetraselmis tetrathele (Butcher) at different phases of culture
(Blackwell Publishing, 2005)A local algal isolate Tetraselmis tetrathele was studied to determine the suitable levels of three growth factors (nutrient medium, light intensity and photoperiod) for mass culture. Significantly higher population cell ... -

Changes in iodide and thyroid hormone levels of hatchery-reared orange-spotted rabbitfish Siganus guttatus (Bloch 1787) during early larval development
(Elsevier, 2021-07)This paper elucidates the developmental profiles of iodide and thyroid hormones, thyroxine (T4) and triiodothyronine (T3) in hatchery-reared rabbitfish (Siganus guttatus) during early larval development. ... -
Changes in mRNA expression of grouper (Epinephelus coioides) growth hormone and insulin-like growth factor I in response to nutritional status
(Elsevier, 2006)Growth hormone (GH) and insulin-like growth factor-I (IGF-I) are key links to nutritional condition and growth regulation in teleost. To understand the endocrine mechanism of growth regulation in grouper, we cloned the ... -
Changes in Na+, K+-ATPase activity and gill chloride cell morphology in the grouper Epinephelus coioides larvae and juveniles in response to salinity and temperature
(Springer Verlag, 2000)The activity of the enzyme Na+, K+-ATPase and morphological changes of gill chloride cells in grouper, Epinephelus coioides larvae and juveniles were determined 6–48 h after abrupt transfer from ambient ... -
Changes in plasma osmolality and chloride concentration during abrupt transfer of milkfish (Chanos chanos) from seawater to different test salinities
(Elsevier, 1988)Milkfish juveniles (40, 120 or 260 g) were acclimated to 32 ppt seawater, then abruptly transferred to water with salinities of 0, 16, 32 (control) or 48 ppt. Blood samples were taken 0, 1, 2, 3, 5, 7 or 14 days after ... -
