Lunar synchronization of spawning in sea bass, Lates calcarifer (Bloch): Effect of luteinizing hormone-releasing hormone analogue (LHRHa) treatment
(Wiley-Blackwell, 1992)
Based on egg collection records, spontaneous spawning activity of sea bass, Lates calcarifer (Bloch), reared in floating net cages followed a semilunar cycle. The peak of multiple spawnings coincided with declining spring ...
The effect of background color and rotifer density on rotifer intake, growth and survival of the grouper (Epinephelus suillus) larvae
(Elsevier, 1996)
Rotifer intake and early growth and survival of Epinephelus suillus larvae were determined in terms of rotifer visibility against the background color of rearing tanks and density. The larvae were stocked at 30 l<sup>−1</sup> ...
Gracilaria (Rhodophyta) farming in Panay, Western Visayas, Philippines
(Elsevier, 1992)
Interviews were conducted among eight Gracilaria growers in Panay, Western Visayas, Philippines from March to July (1990) using a structured questionnaire. The "rice planting" method was employed by farmers growing seaweeds ...
Ammonia excretion in Penaeus monodon postlarvae during handling and transfer
(Society of Israeli Aquaculture and Marine Biotechnology, 1994)
The ammonia excretion rate was used as an index of the physiological state of Penaeus monodon poltlarvae (PL) by monitoring excretion rates after handling and transfer to physiologically different media. The ammonia excretion ...
Growth responses of Spirulina platensis to some physico-chemical factors and the kinetics of phosphorus utilization
(Japanese Society of Fisheries Science, 1995)
The growth responses of Spirulina platensis NIES-46, a brackishwater strain originally isolated from Lake Texcoco Mexico, to some physico-chemical factors and nutrients were investigated. The optimum conditions for growth ...
Effect of some vertebrate and invertebrate hormones on the population growth, mictic female production, and body size of the marine rotifer Brachionus plicatilis Müller
(Springer Verlag, 1997)
Eight vertebrate and invertebrate hormones were screened for their effect on population growth, mictic female production, and body size of the marine rotifer Brachionus plicatilis. Growth hormone (GH) or human chorionic ...
Milkfish (Chanos chanos) production and water quality in brackishwater ponds at different feeding levels and frequencies
(Wiley-Blackwell, 1998)
This study evaluated the effects of different feeding levels and frequencies on milkfish (Chanos chanos) growth, feed efficiency, and water quality in brackish water ponds. Milkfish juveniles (average weight, 1 g) were ...
Reproductive quality of male Penaeus monodon
(Elsevier, 1993)
The reproductive performance of unilaterally eyestalk-ablated wild male Penaeus monodon was compared with that of unablated prawns (controls). After being stocked for 6 weeks in flow-through tanks, ablated males showed ...
An ultrastructural study on the occurrence of aberrant spermatids in the testis of the river sculpin, Cottus hangiongensis
(The Ichthyological Society of Japan, 1992)
The process of spermatogenesis and spermiogenesis in the river sculpin,Cottus hangiongensis, was observed ultrastructurally. During spermatogenesis, some germinal cysts in the seminal lobules were found to contain ...
Carpospore germination and early stages of development in Gracilaria edulis (Gmelin) Silva and Gracilaria rubra Chang et Xia (Gracilariales, Rhodophyta)
(San Carlos Publications, University of San Carlos, 1993)
Carpospore germination and early stages of development in Gracilaria edulis and Gracilaria rubra of the Philippines are described for the first time. Both species follow the "Dumontia type" or the immediate discal type of ...
