Effect of salinity on hemolymph calcium concentration during the molt cycle of the prawn Penaeus monodon
(Springer Verlag, 1989)
Prawns (Penaeus monodon) were obtained from ponds in Iloilo, Philippines, in 1984 and 1985 and maintained in salinities from 8 to 44‰. Total hemolymph calcium was largely affected by molt stage and less so by salinity. A ...
Development of an ovarian biopsy technique in the sea bass, Lates calcarifer (Bloch).
(Elsevier, 1989)
A convenient and rapid biopsy method for taking ovarian samples from mature sea bass (Lates calcarifer Bloch) is described. Intra-ovarian oocytes siphoned with polyethylene tubing from any region of the ovary provide a ...
Ovarian development and changes in the serum vitellogenin levels in the river sculpin, Cottus hangiongensis, during an annual reproductive cycle
(Faculty of Fisheries, Hokkaido University, 1989)
Annual changes in the ovarian development and serum vitellogenin concentration were investigated in the river sculpin, Cottus hangiongensis, sampled monthly from a river in southern Hokkaido, Japan. Ovarian development ...
An evaluation of indigenous protein sources as potential component in the diet formulation for tiger prawn, Penaeus monodon, using essential amino acid index (EAAI)
(Elsevier, 1989)
The essential amino acid index (EAAI) could be used in screening potential protein sources. However, when formulating diets, EAAI should be supported with feeding trials and digestibility tests to determine the extent of ...
Growth and mid-gut cells profile of Penaeus monodon juveniles fed water-soluble-vitamin deficient diets
(Elsevier, 1989)
Growth and changes in the mid-gut cell morphology of Penaeus monodon juveniles were evaluated after feeding for 35 days with semi-purified diets deficient in water-soluble vitamins. Diets were prepared by deleting one ...
