Gonadal maturation, fecundity, spawning and timing of reproduction in the mud snail, Cerithidea cingulata, a pest in milkfish ponds in the Philippines
(Taylor & Francis, 2001)
Gonadal maturation, spawning, fecundity and timing of reproduction of the snail <i>Cerithidea cingulata</i> in a brackish water pond in Molo, Iloilo, Philippines, are described. Snails 4–41 mm in shell length were sampled ...
Use of Acadian marine plant extract powder from Ascophyllum nodosum in tissue culture of Kappaphycus varieties
(Springer Verlag, 2009)
Three varieties of Kappaphycus alvarezii (Kapilaran, KAP), Tambalang purple (PUR), Adik-adik (AA), and one variety of Kappaphycus striatum var. sacol (green sacol (GS) were used to determine the efficiency of Acadian marine ...
Seabream GnRH: partial cDNA cloning, localization and stage-dependent expression in the ovary of snake head murrel, Channa striatus
(Springer Verlag, 2005)
Vertebrate reproduction is under the neuroendocrine control of the hypothalamic decapeptide GnRH which synchronizes various reproductive events and influences other reproduction related aspects like spawning behavior and ...
Effect of tagging on maturation and survival of ablated Penaeus monodon in painted and unpainted tanks
(San Carlos Publications, University of San Carlos, 1989)
A study was conducted to determine the effects of tags and tank color on reproductive performance and survival of pond-reared Penaeus monodon after eyestalk ablation. In 1986, the best over-all reproductive performance was ...
Reproductive performance and larval quality of pond-raised Scylla serrata females fed various broodstock diets
(Asian Fisheries Society, 2001)
Scylla serrata females with initial body weight (BW) of 350 to 400 g were previously raised on a defined diet of 75% brown mussel meat and 25% fish bycatch in grow-out ponds at Molo, Iloilo City, Philippines for 120 days. ...
LHRHa and pimozide-induced spawning of Asian catfish Clarias macrocephalus (Gunther) at different times during an annual reproductive cycle
(Elsevier, 1997)
Captive Clarias macrocephalus were induced to spawn during the off-season (February), before (May), during (August) and end (November) of the natural breeding period to test their seasonal responsiveness to hormone treatment, ...
Studies on the reproductive biology of the Donkey's ear abalone, Haliotis asinina Linné
(Elsevier, 1998)
The sex ratio, initial size at sexual maturity, spawning period, time interval between successive spawnings and fecundity of the Donkey's ear abalone, Haliotis asinina were studied. The sex ratio of wild abalone (>60 ...
Effects of exogenous hormones and broodstock age on the spawning response of captive silver therapon Leiopotherapon plumbeus
(Wiley, 2022)
Evaluation of appropriate hormone and ideal broodstock age for optimal breeding efficiency may ensure the production of good quality eggs and larvae in the hatchery. In this study, the spawning response of captive silver ...
GABA enhances reproduction of the rotifer Brachionus plicatilis Muller: application to mass culture
(Wiley-Blackwell, 2000)
Based on the results of individual and batch culture experiments in small volumes, we conducted experiments in larger volumes of 100 mL, 1 L and 10 L to determine: (1) at what phase of population growth would gamma-aminobutyric ...
Induced spawning by LHRHa and pimozide in the Asian catfish Clarias macrocephalus (Gunther)
(Blackwell Publishing, 1993)
Experiments were conducted to determine the optimum dose of luteinizing hormone-releasing hormone analogue (LHRHa) and pimozide (PIM) injected simultaneously to yield a high ovulation rate and produce sufficient eggs in ...
