Mass production in concrete tanks of sugpo Penaeus monodon Fabricius spawners by eyestalk ablation
(Fisheries Research Society of the Philippines, 1978)
Two batches of 196 and 181 P. monodon females were ablated on one eyestalk in March and July 1977, respectively, and a control batch of 180 unablated females was stocked in July 1977. The females were stocked with males ...
Effect of light quality and eyestalk ablation on ovarian maturation in Penaeus monodon
Prawns were subjected to the following treatments: blue light, red light, natural light, and natural light plus unilateral eyestalk ablation. Unablated prawns under blue and natural light developed stage III ovaries; under ...
Ovarian rematuration of ablated sugpo prawn Penaeus monodon Fabricius
(Institut National de la Recherche Agronomique, 1978)
Spent Penaeus monodon females were tagged around one eyestalk with numbered brass tags, stocked in a concrete tank with males, and periodically examined for ovarian rematuration over a six-month period (February to August, ...
Induced spawning and early life description of the mangrove red snapper, Lutjanus argentimaculatus
(Elsevier, 1994)
Wild-caught mangrove red snapper, Lutjanus argentimaculatus, reared in a concrete tank for 1 year, spontaneously matured in June 1992. On 19 August 1992, a sexually mature female and male (4.6 and 3.2 kg body weight, ...
Induced maturation and spawning in five-month-old Penaeus monodon Fabricius by eyestalk ablation
(Elsevier, 1978)
Pond-reared sugpo (Penaeus monodon Fabricius) females from coastal fry harvested after 4 months were unilaterally ablated and stocked in an indoor concrete tank with an equal number of males. The first two spawnings were ...
Effect of season on oocyte development and serum steroid hormones in LHRHa and pimozide-injected catfish Clarias macrocephalus (Günther)
(Japanese Society of Fisheries Science, 1999)
Oocyte and blood samples were taken from gravid female catfish Clarias macrocephalus at 4-h intervals to monitor the stage of oocyte development and serum steroid hormone profiles after injection of luteinizing hormone-releasing ...
Larval and early juvenile development of silver therapon, Leiopotherapon plumbeus (Actinopterygii: Perciformes: Terapontidae), reared in mesocosms
(Szczecińskie Towarzystwo Naukowe, 2017)
The silver therapon, Leiopotherapon plumbeus (Kner, 1864), is an endemic and economically important freshwater food fish in the Philippines. The natural populations of this species have been declining during the past years, ...
Observations on artificial fertilization of eggs and embryonic and larval development of milkfish, Chanos chanos (Forskal)
(Elsevier, 1978)
Hydrated eggs obtained from a female milkfish, Chanos chanos, were artificially fertilized with the milt collected from a male injected with acetone-dried pituitaries of salmon. The fertilized eggs (1.1–1.25 mm in diameter) ...
Induced maturation and spawning of milkfish, Chanos chanos Forsskal, by hormone implantation
(Elsevier, 1986)
The milkfish, Chanos chanos Forsskal, does not reach gonadal maturity easily in captivity. In an attempt to induce maturation, exogenous hormones, LHRH-A and 17α-methyl-testosterone, were implanted into adult milkfish ...
Use of hormones in breeding cultivated warm-water fishes with special reference to milkfish, Chanos chanos (Forskal)
(Fisheries Research Society of the Philippines, 1978)
The role of hormones in the controlled reproduction of a few test fishes is well documented. However, information on the mechanisms of endocrine regulation of ovulation in cultivated warm-water fishes is very meagre. ...
