The effect of micro algal diet and rearing condition on gonad maturity, fecundity and embryonic development of the window-pane shell, Placuna placenta Linnaeus.
(Elsevier, 2002)
Immature <i>Placuna placenta</i> (Linnaeus) broodstock were given the micro algae <i>Isochrysis galbana</i> (T-ISO) Parke and <i>Tetraselmis tetrahele</i> (G.S. West) at different combinations and density levels and reared ...
Distribution and symptoms of epiphyte infection in major carrageenophyte-producing farms
(Springer Verlag, 2008)
High density commercial farming of carrageenophyte Kappaphycus alvarezii is often plagued with “ice-ice” disease and epiphyte infection, which eventually leads to reduced production and in some cases collapse of crop. ...
Induction of oocyte maturation and ovulation in the freshwater Asian catfish, Clarias macrocephalus by LHRHa and pimozide
(Blackwell Publishing, 1992)
Three experiments were conducted to determine the effects of a simultaneous injection of varying doses of luteinizing hormone-releasing hormone analogue (LHRHa; 0.005–0.10 μg)/body weight (BW) in combination with a fixed ...
Effects of unilateral eyestalk ablation on ovarian histology and oocyte size frequency of wild and pond-reared Penaeus monodon (Fabricius) broodstock
(Elsevier, 1991)
Effects of eyestalk ablation on ovarian maturation of wild and pond-reared Penaeus monodon were determined to compare their reproductive potential. This was done by counting the oocyte size frequency in four regions of the ...
Ovarian development in relation to changes in the external genitalia in captive Penaeus monodon
(Elsevier, 1993)
Hatchery-reared Penaeus monodon postlarvae were cultured in ponds until they attained adult size. Thereafter, the shrimps were transferred to concrete broodstock tanks for maturation. During the culture period, the ...
Effect of dietary astaxanthin and vitamin A on the reproductive performance of Penaeus monodon broodstock
(Cambridge University Press, 1998)
The reproductive performance of pond tiger shrimp given astaxanthin (100 mg·kg<sup>−1</sup>) and/or vitamin A (20 000 IU·kg<sup>−1</sup>) for 61 d in tanks was assessed in a 2 × 2 factorial experiment in a completely ...
Year-round sexual maturation of bighead carp Aristichthys nobilis (Richardson) reared in floating cages in Laguna de Bay (Philippines).
(Blackwell Publishing, 1990)
Sexual maturation in bighead carp Aristichthys nobilis reared without supplemental feeding in floating cages in Laguna de Bay was observed year-round. Percent maturation ranged from 3 to 94% in females and 0 to 82% in males ...
Effects of unilateral eyestalk ablation on growth and reproductive parameters in wild and pond-reared Penaeus monodon (Fabricius) broodstock
(San Carlos Publications, University of San Carlos, 1991)
Effects of unilateral eyestalk ablation on wild and pond-reared Penaeus monodon during ovarian maturation were determined by examining the growth (e.g., carapace length, body length, body weight) and reproductive (e.g., ...
Tissue lipid content and fatty acid composition of Penaeus monodon Fabricius broodstock from the wild
(Wiley-Blackwell, 1990)
Tissues (hepatopancreas, muscle, gonad) of wild Penacus mordon females with ovaries in different stages of development and males were analyzed for Upid content and fatty acid composition. Hepatopancreatic tissue had the ...
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 ...
