JOURNAL FREE ACCESSThe part eight of this series contains descriptions of life colors of the species Nos. 112-131, with some notes on the fishes (several species of Apogonidae, Emmelichthyidae, Priacanthidae, Pomatomidae, Histiopteridae, and Serranidae) found in Suruga Bay, Japan.View full abstractDownload PDF (767K) -

JOURNAL FREE ACCESSThe writer has furthermore enumerated seventeen unrecorded species and one uncommon subspecies of fish with brief descriptions, which are to be newly added into a list of fish of Niigata Prefecture and its adjacent waters, the Sea of Japan. Here the writer has checked 481 species of fish from the waters around Niigata prefecture.
Among the fish to be added herein, there is a small strange cottid fish, Atopo cottus tribranchius BOLIN 1936, as the second record which has been only obtained from the offshore of Niigata City during the cruise of the U.S. Bureau of Fisheries steamer “Albatross” in 1906.View full abstractDownload PDF (2241K) -

JOURNAL FREE ACCESSThe headpart of the loach was perfused with physiological saline solution. The intestinal respiration was observed so long as preparations were kept in air. When they came into contact with water, the frequency of the intestinal respiration decreased and the gill respiration started. On the other hand, in the preparations held in water only the gill respiration occurred. Adding of a little volume of CO2-rich solution to perfusate caused the gill-respiration even in the preparations exposed to air. Mean while, fastened on the waterbottom, movements for intestinal respiration could be observed. Addition of lactic acid instead of CO2 did not accelerate any forms of respiration, and sudden deflections of headpart were noticed.
The author wishes to express his heartful thanks to Prof. SUYEHIRO for constant guidance in the course of the work. Thanks are also due to Assist. Prof. HIBIYA for valuable suggestions.View full abstractDownload PDF (831K) -

JOURNAL FREE ACCESSA landlocked salmonoid fish from the mountains of Formosa was described by JORDAN and OSHIMA (1919) as Salmo formosanus. Japanese workers have since considered this fish in the genus Oncorhynchus. MILLER (1950: 33) points out that since the gender of Oncorhynchus is neuter, formosanus must be written formosanum.
On the basis of scale structure, OSHIMA (1934) concluded there were no differences between O. formosanum of Formosa and the small landlocked salmon, O. masou, of southern Japan. A recent examination of specimens in the Stanford University Collection has uncovered some new evidence concerning the systematics of these fish.
A single specimen of O. formosanum was examined (S. U. 23059). This specimen showed differences from samples of Japanese landlocked salmon collected from Lake Biwa and the Daiya River, Nikko. Since the sample sizes were small, it would be unwise to place a great significance on them, but one outstanding character noticed in O. formosanum was the presence of basibranchial teeth. These teeth, often called hyoid teeth, are found in no other Oncorhynchus and only in Salmo clarkii of the genus Salmo. They were not mentioned in the original description of this fish.
If all of the landlocked salmon of Formosa possess basibranchial teeth while the Japanese salmon lack this character, they cannot be considered identical. Further work may indicate that O. formosanum should be placed with Salmo as originally proposed by JORDAN and OSHIMA (op.cit.). However, a thorough study would be neccessary to give much credence to such a decision.
Eleven specimens of O. masou were examined, 5 from the Daiya River, Nikko (S. U. 6700), labeled Oncorhynchus ishikawae, and 6 from Biwa (S. U. 6693), labeled Salmo macrostomus. The following table indicates some of the differences between O. formosanum and O. masou.View full abstractDownload PDF (151K) -
Record of a rare species Photostomias guernei COLLETT of the Family MalacosteidaeKeisuke MARUYAMA1959 Volume 7 Issue 5-6 Pages 153-156

JOURNAL FREE ACCESSIn this paper is given description of a rare deep-water fish Photostomias guernel COLLETT of the family Malacosteidae that was collected in connection with a survey of bottom fish resourses of Hachinohe Branch Laboratory.
This species has been recorded already by Dr. S. IMAI (1957) from Suruga Bay, in Japanese water.
One of the specimens examined bears no data excepting for the record that it was collected from off Tohoku and adjacent regions . Its total length is 87mm. Other specimen was taken out from the stomach of Theragra chalcogramma (PALLAS) that was taken by the bottom trawl without otter board on Aug. 19-20, 1957, from a depth of 450m at the fishing grounds section No.176, off Hachinohe, Aomori Pref. Its total length is 123mm. These specimens have characters of the male form that were described by REGAN & TREWAVAS (1930), and the body proportions well agree with COLLETT'S, REGAN and TREWAVAS'S and IMAI'S description except tor a few difference of the diamater of eye and the number of the lateral photophores.View full abstractDownload PDF (2208K) -

JOURNAL FREE ACCESSTwo species of Beryx, hitherto recorded as “splendens” and “decadactylus”, respectively, are fished commercially during autumn through spring by hook and line from the depths off Izu-Oshima, in Sagami Bay and off south-eastern coast of Boso Peninsula (south of Tokyo), and since March, 1958, considerable quantity of “splendens” has been taken by trawl off Chashi (Chiba Prefecture east of Tokyo). Deep line fish ermen in Odawara City are the most active in finding new fishing grounds for larger fishes of Beryx, and interested in their migration and life histories. The writer has often been asked to give lectures on Beryx and other deep-sea fishes for these fishermen, and has obtained in return from them valuable specimens of deep sea fishes, information and suggestions relevant to the ecology of the fishes. He takes great pleasure in expressing here his sincere thanks to them and to Mr. Y. HONDA (Agiculture and Fisheries Division, Odawara Municipal Office) for the cooperation, and more especially, for the specimens of the third species of Beryx from Sagami Bay which they call “Fusen-kinme” (meaning balloon Beryx). This species is believed new to science, and described below. It is rather rare in Sagami Bay. The writer has never seen it at the Central Wholesale Market of Tokyo.View full abstractDownload PDF (9909K)
