Volume 19 Winter 2002 the Coral Hind, Lapu Lapu, Or Miniata
FREE ISSN 1045-3520 Volume 19 Winter 2002 Introducing a Zonal Based Natural Photo by Robert Fenner Filtration System for Reef Aquariums by Steve Tyree Quite a few natural based filtration systems have been devised by reef aquarists and scientists in the past twenty years. Some systems utilized algae to remove organic and inorganic pollutants from the reef aquarium; others utilized sediment beds. The natural filtration system that I have been researching and designing is drastically different from both of these types. No external algae are used. I believe that all the algae a functional reef requires are already growing in the reef, even if they are not apparent. They include micro-algae, turf algae, coralline algae, single-cell algae within photosynthetic corals, and cyanobacteria with photosynthetic capabilities. Most of the systems that I have set up to research this concept have not included sediment beds. All organic matter and pollutants are recycled and processed within the system by macro-organisms. Sediment beds have not been utilized to process excess Miniata Grouper, Cephalopholis miniata organic debris, but that does not prevent other aquarists from adding them. The main concept behind my system is the use of living sponges, sea squirts, and filter feeders for filtration. Sponges consume bacteria, can reach about twenty inches in length in the wild, and dissolved and colloidal organic material, micro-plankton, The Coral Hind, Lapu about half that in captivity. It is undoubtedly the most and fine particulate matter. Sea squirts consume large Lapu, or Miniata prized member of the genus for the aquarium trade. -
Recruitment in Anemonefishes
Interspecific, Spatial and Temporal Variability of Self- Recruitment in Anemonefishes Hawis H. Madduppa1*, Janne Timm2, Marc Kochzius3 1 Marine Science and Technology, Faculty of Fisheries and Marine Science, Bogor Agricultural University (IPB), Bogor, Indonesia, 2 Biotechnology and Molecular Genetics, University of Bremen, Bremen, Germany, 3 Marine Biology, Vrije Universiteit Brussel, Brussels, Belgium Abstract Polymorphic microsatellite DNA parentage analysis was used to investigate the spatio-temporal variability of self- recruitment in populations of two anemonefishes: Amphiprion ocellaris and A. perideraion. Tissue samples of A. ocellaris (n = 364) and A. perideraion (n = 105) were collected from fringing reefs around two small islands (Barrang Lompo and Samalona) in Spermonde Archipelago, Indonesia. Specimens were genotyped based on seven microsatellite loci for A. ocellaris and five microsatellite loci for A. perideraion, and parentage assignment as well as site fidelity were calculated. Both species showed high levels of self-recruitment: 65.2% of juvenile A. ocellaris in Samalona were the progeny of parents from the same island, while on Barrang Lompo 47.4% of A. ocellaris and 46.9% of A. perideraion juveniles had parents from that island. Self-recruitment of A. ocellaris in Barrang Lompo varied from 44% to 52% between the two sampling periods. The site fidelity of A. ocellaris juveniles that returned to their reef site in Barang Lompo was up to 44%, while for A. perideraion up to 19%. In Samalona, the percentage of juveniles that returned to their natal reef site ranged from 8% to 11%. Exchange of progeny between the two study islands, located 7.5 km apart, was also detected via parentage assignments. -
Seed Production and Culture of Marine Ornamental Fishes G
Course Manual Seed Production and Culture of Marine Ornamental Fishes G. Gopakumar, A. K. Abdul Nazar and R. Jayakumar Mandapam Regional Centre of CMFRI Mandapam Camp - 623 520, Tamil Nadu, India Introduction The marine ornamental fish trade has been expanding in recent years and has grown into a multimillion dollar enterprise. The ornamental animals are the highest valued products that are mostly harvested from coral reef environments. The global marine ornamental trade is estimated at US$ 200-330 million. The trade is operated throughout the tropics. Philippines, Indonesia, Solomon Islands, Sri Lanka, Australia, Fiji, Maldives and Palau supplied more than 98% of the total number of marine ornamental fish exported in recent years. It is a multi-stakeholder industry ranging from specimen collectors, culturists, wholesalers, transhippers, retailers, and hobbyists to researchers, government resource managers and conservators and hence involves a series of issues to be addressed and policies to be formulated for developing and expanding a sustainable trade. It is well understood that a long term sustainable trade of marine ornamental fishes can be developed only through the development and commercialization of hatchery production technologies for the species which are in high demand in the trade. Global scenario In recent years it has been reported that nearly 1500 species of marine ornamental fishes are traded globally and most of these are associated with coral reefs. Nearly 98% of the marine ornamental fishes marketed are wild collected from coral reefs of tropical countries. Among the most commercially traded families of reef fishes, family Pomacentridae dominate, accounting for nearly 43% of all fish traded. -

Accepted 22 January, 2014 In the present investigation, a total of 5 species belonging to three genera such as Pomacanthus, Centropyge and Apolemichthys were reported from the 10 selected stations of Tamilnadu, south east coast of India. The diversity studies revealed that the species diversity, richness and evenness were comparatively higher at Rameshwaram and Kanniyakumari due to the rocky shore and coral reef ecosystem. Species composition study revealed that the smoke angel (Apolemichthys xanthurus) was found to be dominant group which constituting 57% of total fishes. The results of the present study evidenced that the occurrence and distribution of marine angel fishes were higher in Gulf of Mannar than other region of Tamilnadu. The present findings clearly explained about distribution pattern of marine angel fishes which could be useful for better understanding of the status of its diversity along southeast coast of India and also highlights the need for effective conservation measures of these commercially important marine ornamental fish group.

Reproductive Biology of Pigmy Angelfishes of the Genus <I
BULLETIN OF MARINE SCIENCE. 31(3): 495-513. 1981 REPRODUCTIVE BIOLOGY OF PIGMY ANGELFISHES OF THE GENUS CENTROPYGE (POMACANTHIDAE) J. A. Bauer Jr. and S. E. Bauer ABSTRACT Centropyge are long lived territorial coral reef inhabitants which adapt well to aquaria for extended periods (8+ years). They are well suited for reef and laboratory study of reproductive behavior and may also serve as a model for pomacanthids in general. The spawning behavior of six species of Centropyge. including two Atlantic and four Pacific species, was studied in the laboratory for periods of 4 to 7 years. Extensive coral reef observations were made of three species of Centropyge. Harem groups of the same fishes were observed on consec- utive days on their reef territory. The proposed "Continuous Spawning Strategy" is distinct and different from marine spawning strategies described previously and consists of a well-sustained, stress-free, daily gamete production and results in larval dispersal which is maximal and continuous. Based on reef and tank observations, Celltropyge spawning consists of: (I) a crepuscular spawning ritual, which is (2) a regular d:!qy activity of the harem group and (3) usually results in spawn- ing, but may have other functions as well. (4) Each female spawns a moderate number of eggs every day continuously throughout the year or during a season depending on latitude. (5) Territory has predominantly reproductive significance and is defined by the spawning ritual. (6) Each female spawns only once each day with the harem male. (7) The spawning ritual provides defense from predation. Embryogenesis of Celltropyge is presented. -
