Spawning Cycle of Two Dragonet Species, Calliurichthys Japonicus and Repomucenus Huguenini, in Tosa Bay, Southern Japan Fisheries Science 63(1), 15-21 (1997) Spawning Cycle of Two Dragonet Species, Calliurichthys japonicus and Repomucenus huguenini, in Tosa Bay, Southern Japan Benjamin Jareta Gonzales,*1,*3 Nobuhiko Taniguchi,*1,•õ and Osamu Okamura*2 *1Department of Fisheries , Faculty of Agriculture, Kochi University, Nankoku, Kochi 783, Japan *2Department of Biology , Faculty of Science, Kochi University, 2-5-1 Akebono-cho, Kochi 780, Japan *3State Polytechnic College of Palawan -Institute of Marine Sciences , Puerto Princesa City 5300, Philippines (Received February 9, 1996) The spawning cycle of Calliurichthys japonicus and Repomucenus huguenini was investigated from March 1992 to February 1993 in a wild population in Tosa Bay, Kochi Prefecture. Calliurichthys japonicus is an annual spawner, having high reproductive activity in summer. The species appears to spawn mainly between 90-120m water depth and extends its spawning ground to shallower waters of the Bay during the peak reproductive period in July. Maturity of females occurs at 12.5cm in SL and 17.7 cmSL in male. Repomucenus huguenini is a biannual spawner, spawning within its normal distri bution range of 15-30m water depth during spring (May) and autumn (October to December with a peak in November). This species matures and reproduces from an early age with maturity estimated to occur at 4.5cm SL in both sexes. The temperature in 45-120m when the GI of C. japonicus samples was at its peak in July, ranged from 17.4-21.6•Ž and salinity from 34.6-35.0. During the peak reproductive season of R. huguenini in November, the temperature ranged from 22.4-22.8•Ž and salini ty from 34.4-34.6in 15 to 30m water depth.

The gonads were removed and weighed to the nearest 0.01mg. The monthly mean gonad index (GI) of both species were determined, and the maturation stage of the oocytes of adult fish specimens collected during the peak spawning months were observed under a microscope. The sex of small individuals (C. japonicus, <9cm SL; R. huguenini, <6cm SL) was determined initially by such morphological characters as the relatively longer length of the filamentous finrays on the first dorsal fin in male R. huguenini, the relatively longer tail length to body length of male C. janonicus, and the relatively elongated genital organ of males in both species. Sex was finally confirmed by the shape and color of the testis (elongated and dark color) and the ovary (rounded and milky white). The GI was calculated using the formula: Gl=gonad weight (g) •~ 104/ SL3(cm). In C. japonicus, only female specimens of length ? 12.1cm SL and male specimens ?17.0cm SL were used for GI analysis, while in R. huguenini, male and female specimens with length sizes ? 4.5cm in SL were used (Fig. 2).

Grant Gilmore, Jr. Christopher Donohoe Dougl as Cooke Davi d Herrema INTRODUCTION It is the intent of this presentation to briefly describe regional fish habitats and to list the fishes associated with these habitats in the Indian River lagoon, its freshwater tributaries and the adjacent continental shelf to a depth of 200 m. A brief historical review of other regional ichthyological studies is also given. Data presented here revises the first regional description and checklist of fishes in east central Florida (Gilmore, 1977). The Indian River is a narrow estuarine lagoon system extending from Ponce de Leon Inlet in Vol usia County south to Jupiter Inlet in Palm Beach County (Fig. 1). It lies within the zone of overlap between two well known faunal regimes (i.e. the warm temperate Carolinian and the tropical Caribbean). To the north of the region, Hildebrand and Schroeder (1928), Fowler (1945), Struhsaker (1969), Dahlberg (1971), and others have made major icthyofaunal reviews of the coastal waters of the southeastern United States. McLane (1955) and Tagatz (1967) have made extensive surveys of the fishes of the St.
