Multiple gonadal maturation and re-maturation after hormone-induced spawning in bighead carp Aristichthys nobilis Rich.
(San Carlos Publications, University of San Carlos, 1991)
Gonadal maturation and rematuration after hormone-induced spawning in cage-reared female bighead carp Aristichthys nobilis were observed. Percent maturation ranged from 54 to 100% for females and 0 to 40% for males. ...
Developmental trends in the mouthparts during growth from juvenile to adult of the tropical freshwater crayfish, Cherax quadricarinatus von Martens, 1868 (Decapoda: Parastacidae)
(International Society of Invertebrate Reproduction and Development, 1997)
The structure and setal armature of the mouthparts of Cherax quadricarinatus during development from juvenile to adult were examined using light and scanning electron microscopy. Significant general transformations include ...
Tissue lipid content and fatty acid composition during ovarian maturation of ablated Penaeus monodon
(Society of Israeli Aquaculture and Marine Biotechnology, 1993)
The total lipid content and fatty acid composition in the hepatopancreas, muscle and gonad of ablated Penaeus monodon females at ovarian maturation Stages I to V were examined. The lipid content was highest in the ...
Bioactivity of stored luteinizing hormone-releasing analogue (LHRHa) in sea bass, Lates calcarifer Bloch
(Wiley-Blackwell, 1996)
The spawning induction activity of dissolved and pelleted (D-Ala<sup>6</sup>, Pro<sup>9</sup> N ethylamide) luteinizing hormone-releasing hormone analogue (LHRHa) stored for various periods was assessed in mature female ...
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., ...
