Taxonomic Study Of Pike Congers (Anguilliformes: Muraenesocidae) With Identification Of Muraenesocid Collections In Taiwan, James Lin, Kwang-Tsao Shao, Hong-Ming Chen
Journal of Marine Science and Technology–Taiwan
During the past years, we collected and studied on the Anguilliformes fishes, and described some new genera and new species of eels. We noticed that there are some misidentified species or invalid junior synonym in Muraenesocidae specimens. Considering how limited this family is known in Taiwan, we would like to revise the species of pike congers here. We collected muraenesocid specimens around Taiwan from fish markets, fishery harbors, fishermen, and also examined the specimens from other Taiwanese museum collections. Comparing to the past literature of Muraenesocidae, we found that the species Congresox talabon was misreported previously, and there is not …

Genetic Diversity Of Filamentous Cyanobacteria From Shore Regions Of Okinawa, Shoichiro Suda, Rui Moriya, Shinpei Sumimoto, Osamu Ohno, Kiyotake Suenaga
Journal of Marine Science and Technology–Taiwan
Benthic marine cyanobacteria are ubiquitous oxygenic photosynthetic bacteria and they form major components of various communities, including epiphytic, epilithic and microbial mats, in coral reef environments. Filamentous groups may form almost monospecific macroscopic colonies, and sometimes make potentially harmful algal blooms (HABs). HABs bring serious problems for marine tourism but marine filamentous cyanobacteria are good resource for drug discovery. However, cultivation and identification of such filamentous cyanobacteria are difficult and there are taxonomic confusions. In this study, we investigate 17 samples from coral reef area of 10 localities in Okinawa. Macroscopic mats or cushions of filamentous cyanobacteria were collected. The …

Diversity Of Crypthecodinium Spp. (Dinophyceae) From Okinawa Prefecture, Japan, Danang Ambar Prabowo, Ooshi Hiraishi, Shoichiro Suda
Journal of Marine Science and Technology–Taiwan
The genus Crypthecodinium (Dinophyceae) currently consists of only one species: C. cohnii, a heterotrophic marine dinoflagellate widely known able to produce prolific amount of DHA. However, previous studies revealed that there are morphological and genetic differences among Crypthedodinium cohnii-like strains, indicating the potential of undiscovered diversity of this dinoflagellate. Attempts of isolating heterotrophic marine dinoflagellate strains were made from submerged mangrove leaves and seaweed. A total of nine strains were established, cultured and maintained using seawater-based GTY medium for taxonomic identification and phylogenetic analyses based on SSU, ITS1, 5.8S, ITS2 and LSU rDNA. Morphological observation revealed all strains shared similar …

Adult sea urchins, Anthocidaris crassispina, were reared individually in running seawater equilibrated with gas mixtures containing 380 ppm (control), 1,000 ppm or 3,000 ppm CO2, at ambient natural temperature for 140 days to study effects of elevated CO2 on feed intake, fecal production, oxygen consumption, and the morphology of Aristotle’s lantern. Feed intake became significantly lower in the two high CO2 groups than in the control after 90 (1,000 ppm) or 110 (3,000 ppm) days and remained suppressed until the end of the experiment (control, 0.16 ± 0.01 (mean ± SE) g dry wt ind-1 day-1; 1,000 ppm, 0.10 ± …

The tropical and subtropical eel family Ophichthidae are the most diverse Anguilliformes fishes which occupy a variety of marine habitats such as reefs, sand and mud substrates. In Taiwan, we can often collect them from the capture of bottom-trawl fishery. In this study, we added two new recorded species Ophichthus machidai and O. obtusus of ophichthid eels collected from Da-xi fish market by comparing their morphological measurements, vertebral counts and head pores with the other six species of the genus Ophichthus: O. apicalis, O. aphotistos, O. asakusae, O. erabo, O. tsuchidae, O. urolophus.

Alternative Assessment Methods Applied To The Hairtail (Trichiurus Lepturus) Stock In The Aru Sea As An Example, Chao-Hsiung Cheng, Tsuyoshi Kawasaki, Kuo-Ping Chiang, Chuan-Hung Ho
Journal of Marine Science and Technology–Taiwan
The Aru Sea off Indonesia is a major fishing ground for Taiwanese distant-water otter trawlers. The hairtail, an economically important demersal fish, is abundant in that area. The assessment methodology in this paper extends previous studies on hairtail fisheries by considering migration within the fishing grounds. This model is based on conventional Leslie-Delury method but makes different assumptions on stock movement and the relationship between stock abundance and catch per unit effort. It was applied to retrospective data from the hairtail fisheries in the Aru Sea. In addition, the depletion method was used to estimate the abundance of hairtail and …

Identification And Analysis Of White Spot Syndrome Virus (Wssv) Envelope Protein Vp41a, Po-Yu Huang, Pei-Jung Chen, Huai-Ting Huang, Li-Li Chen
Journal of Marine Science and Technology–Taiwan
White spot syndrome virus (WSSV) is the causative agent of a disease that has led to severe mortalities of cultured shrimp in Taiwan and many other countries. WSSV, a kind of large enveloped DNA virus, has a wide host range among crustaceans. During the first stage to infect a target cell, the enveloped virus must combine itself with the receptor on the host cell membrane via an envelope protein. In WSSV, binding of envelope protein with the receptor of the host cell membrane was revealed in a number of previous studies. WSSV envelope proteins were also considered to form a …

How Important Is Viral Effect On The Measure Bacterial Growth In Western Subtropical Pacific Coastal Water?, An-Yi Tsai, Gwo-Ching Gong, Kuo-Ping Chiang, Jie Hung
Journal of Marine Science and Technology–Taiwan
Bacterial growth rates were determined in natural seawater samples using two different methodological approaches: incubation in dialysis bags, and a modification of the dilution approach. Bacterial growth rates estimated for the dialysis bag varied from 0.026 h-1 (April) to 0.208 h-1 (August). Bacterial growth rates in 0.2 µm and 30 kDa size-fractionated series ranged from 0.038 to 0.094 h-1 and 0.078 to 0.42 h-1, respectively. Furthermore, in all of our samples, growth rates in the 30 kDa fractionated series (grazer and virus-free diluent) were higher than in the 0.2 µm series (grazer-free diluent) or in the dialysis bag incubations.

We studied the prey consumption rates in Apocyclops royi on neonate and adult rotifers, Brachionus rotundiformis and ciliate, Euplotes sp. in the presence and absence of algae, the smaller Isochrysis galbana and the larger Tetraselmis chui. Both males and females of A. royi were able to successfully ingest neonate and adult rotifers and ciliate. The prey consumption rates were significantly lower in males than in females of A. royi. Regardless of sex and reproductive state of the copepod, prey consumption rates were higher on neonates rotifer than on adults. However, the prey consumption rates were significantly lower on ciliate than …

A sailfish (Istiophorus platypterus) was tagged with a pop-up satellite archival tag off the eastern coast of Taiwan and moved in a northerly direction to the East China Sea, where the tag popped-up after 160 days. The total linear displacement was 550 km from deployment to pop-up location and all movements were confined to the East China Sea. After the primarily southward movement during first two months at-liberty, the sailfish changed course after September and began to swim in a northerly direction paralleling the Kuroshio Current. During these horizontal movements, the tagged animal exhibited diel oscillations in its vertical diving …

The genus Pyramimonas Schmarda was traditionally described on observations of its periplast and internal structure of different flagellar apparatus or eyespot orientations and currently comprises of ca. 60 species that are divided into six subgenera: Pyramimonas, Vestigifera, Trichocystis, Punctatae, Hexactis, and Macrura. In order to understand the genetic diversity and phylogenetic relationships of genus Pyramimonas members, we analyzed nuclear SSU rDNA molecular data from 41 strains isolated from different locations of the Ryukyu Archipelago. Phylogenetic analyses revealed that strains could be segregated into six clades, four of which represented existing subgenera: Pyramimonas, Vestigifera McFadden, Trichocystis McFadden, and Punctatae McFadden, and …
