Spawning aggregation of white-streaked grouper Epinephelus ongus: spatial distribution and annual variation in the fish density within a spawning ground
White-streaked grouper (Epinephelus ongus) is an important fisheries target and forms spawning aggregations at particular spawning grounds. The aims of the present study were to investigate the ecological characteristics of annual spawning aggregations such as (1) spatial variations in the density of E. ongus at the spawning ground, (2) the relationship between fish density and environmental va...
متن کاملLength-weight relationships and condition factors of the whitespotted grouper Epinephelus coeruleopunctatus Bloch, 1790 in the coastal waters of Padang City, Indonesia
The whitespotted grouper Epinephelus coeruleopunctatus is one of the commercial marine fish species occurred in the coastal waters of Padang city, Indonesia. The population of the whitespotted grouper has been declining over last decade. Unfortunately, there was a lack of information on the biology of this species was available. Hence, the objectives of the present research were to examine the ...
متن کاملThe effect of spine postures on the hydrodynamic drag in Epinephelus ongus larvae.
Laboratory behavioural observation and computational fluid dynamics (CFD) analysis were conducted to examine whether the movement of the elongated dorsal and pelvic spines changed the hydrodynamic drag in white-streaked grouper Epinephelus ongus larvae. The behavioural observation in the tank revealed that the larvae extended the dorsal and pelvic spines during passive transport and retracted d...
متن کاملHermaphroditism in the white spot grouper Epinephelus coeruleopunctatus (Pisces: Serranidae) harvested from Padang City waters, Indonesia
The objective of the present study was to determine the length (mm) for sex transformation of hermaphroditism in white spot grouper Epinephelus coeruleopunctatus as a basis for developing breeding technology. Fish sampling was carried out between April and October 2013 in Padang City waters, Indonesia. A total of 56 white spot groupers were recorded during the study; of these 22 were male, 28 f...
متن کاملParasite diversity as an indicator of environmental change? An example from tropical grouper (Epinephelus fuscoguttatus) mariculture in Indonesia.
Fish parasites are used to monitor long-term change in finfish grouper mariculture in Indonesia. A total of 210 Epinephelus fuscoguttatus were sampled in six consecutive years between 2003/04 and 2008/09 and examined for parasites. The fish were obtained from floating net cages of a commercially run mariculture facility that opened in 2001. The fauna was species rich, consisting of ten ecto- an...
