Abstract The geographical distribution patterns of two closely-related wrasses, Pseudolabrus eoethinus and P sieboldi, on the Pacific and Sea of Japan coasts of southern Japan were examined. Relative frequencies of the two species were sur-veyed in 53 localities (six bordering the Sea of Japan), based on 586 specimens, 91 photographs and a total of 724 minutes of diving observations. Although the distri-butions of the two species broadly overlapped, P. eoethinus was exclusively distrib-uted along the southernmost parts of the peninsulas projecting into the Pacific Ocean, such as Kii Peninsula and Izu Peninsula, except in some protected areas (e.g. around the Koza River mouth near southernmost Kii Peninsula and within the Shimoda City harbor, southernmost Izu Peninsula). On the other hand, P. sieboldi was exclusively distributed in the innermost parts of bays opening to the Pacific (e.g. Sagami and Osaka Bays), and in the Seto Inland Sea and Sea of Japan. These geographical distribution patterns of the two species suggested that P. eoethinus preferred relatively warm, saline waters strongly influenced by the Kuroshio Cur-rent, whereas P. sieboldi preferred relatively cold, less saline waters not or only weakly influenced by the current. It was inferred that the two closely-related wrasses were able to coexist partly by differences in their preferred habitats.

<I>Cynoglossus abbreviatus</I> spawns from mid-March to mid-April in the Sea of Shimabara in Kyushu. During the spawning season ovarian maturation was successfully induced by injection of the pituitary homogenate of <I>Hypophthalmichthys molitrix</I>. The dose of the aceton-dried pituitary homogenate was 6.5 mg/kg body weight of <I>C. abbreviatus</I>. It took about 2 days for ovulation after injection at a water temperature of 14 to 16&deg;C. Artificial fertilizations were accomplished on March 29, 1974 and again on April 7, 1984, using the females matured by hormone injection in the latter case only. The larvae were reared on the rotifers, <I>Artemia nauplii</I>, <I>Tigriopus japonicus</I> and copepods collected from the sea over a period of 113 days in 1974 and 58 days in 1984. The eggs were pelagic, spherical, 1.19-1.23 mm in diameter and had 30-50 oilglobules of 0.068-0.095 mm in diameter, and the perivitelline space was narrow. The incubation period was 90-98 hours at a water temperature of 14 to 16&deg;C. The newly hatched larvae were 3.18-3.45 mm TL and had 61-64 myomeres. The larvae had many melanophores and xanthophores on the body, forming three bands on the caudal region, but were lacking chromatophores on the finfolds. The yolk was completely absorbed when the larvae attained a size of 4.7-5.6 mm TL 8 days after hatching. A single elongated dosal fin ray developed on the head in the 8-day old larvae. The ray was reduced in size as long as the other rays 1 or 2 days after metamorphosis. The rudiment of pectoral fins were found on the both sides of the body in the 2-day old larvae, but two of them disappeared after metamorphosis. A pelvic fin first appeared as a ventral bud just anterior to the gut in the larva of 8.39 mm TL. The full count of 4 rays was observed on the larva of 10.83 mm TL. Metamorphosis began 22 days after hatching when the larvae were 11.20 mm TL. The right eye began to shift the left side of the head at night and reached to the final place after 8.5 hours. It took about 36 hours to complete the metamorphosis, including the eye movement and fusion of the hole in the rostral beak. At the last stage of metamorphosis, the dosal, caudal, anal and ventral fins became confluent. The larvae reached the juvenile stage at a size of 13.5-14.0 mm TL, approximately 28 days after hatchling. The growth of larvae reared in 1974 is expressed by the following equations:<BR>Y<SUB>1</SUB>=3.448&middot;1.0507<SUP>x</SUP> (8&le;X&le;28)<BR>Y<SUB>2</SUB>=6.3322&middot;1.0275<SUP>x</SUP> (28&le;X&le;75)<BR>where Y is the total length (mm) and X is the number of days after hatching. Growth rate changed after metamorphosis.

We examined the role of olfaction involved in schooling of Japanese sea catfish Plotosus lineatus, and attempted to elucidate the relationship between the sensitivity to an aggregating pheromone and bodylength in reference to a reduction of the school size with growth in Japanese sea catfish. Behavioral test of preferenCe for sea water which had held their own school were carried out on 97 fish (42 to 235mm in total length), using filtrated sea water or sea water which had held another school as a control. The catfish discriminated and selected the sea water holding their own school. However, anosmic fish no longer discriminated their holding sea water, suggesting that this preference leading to a school was established by olfaction but not other sense organs including taste. No distinct change in the preference with fish growth was recognized. However, larger fish especially maturing females tended to show a lowered preference. This suggests that reduction in the constituent members of the school with growth in Japanese sea catfish was dependent upon breakaway from menace of predators or upon dispersal of maturing females from their school to avoid incest breeding.

Clutch and egg size in the Japanese amphidromous goby, <I>Rhinogobius</I> sp.DA (<I>R. brunneus</I>, dark type), inhabiting small rivers in the southern part of the Kii peninsula were examined. Clutch sizes, ranging between 1043 and 4436, increased with increasing maternal standard length. Spawned egg volume ranged between 0.85 mm<SUP>3</SUP> and 1.38 mm<SUP>3</SUP>, mean egg volumes being similar among the eight rivers sampled during the study. <I>Rhinogobius</I> sp.DA had a relatively larger egg and smaller clutch size compared to those of three other amphidromous <I>Rhinogobius</I> species inhabiting relatively larger rivers in the same region. Inter-specihic egg size variations among the four species appear to result in differing larval survival rates during their migration to the sea.

Compared with the other anguillid eel species native to Japan (Anguilla japonica and A. marmorata), very little is currently known about the Japanese populations of A. bicolor pacifica. Three specimens of the latter (652.4–879.1 mm total length), collected in an irrigation channel on Iriomote Island, southern Japan, were examined, and the phylogenetic and morphological characters of the species discussed. The stomach contents of two specimens included a number of frog remains.

Somatic chromosomes of the nigorobuna (<I>C.auratus grandoculis</I>) obtained from Lake Biwa, two local varieties of the nagabuna (<I>C.auratus buergeri</I>) from Lake Suwa and the Hokkaido district, and two local varieties of the ginbuna (<I>C.auratus langsdorfii</I>) from the Okayama Prefecture and Lake Biwa were studied and compared.Chromosome preparations was performed by the same methods previously described (Kobayasi et al., 1970).<BR>The results showed that the nigorobuna and nagabuna of Lake Suwa and the ginbuna of the Okayama Prefecture had the same diploid chromosome number of 100.Their karyotypes consisted of 10 pairs of metacentrics, 20 pairs of submetacentrics and 20 pairs of acrocentric elements.There was no morphological difference between the male and female karyotypes. On the other hand, 5 females of the nagabuna collected from the Hokkaido district and 4 females of the ginbuna (hiwara) from Lake Biwa had the chromosome number of 156, consisting of 17 pairs of metacentrics, 31 pairs of submetacentrics and 30 pairs of acrocentrics. The populations of the ginbuna and nagabuna in these regions consisted mostly or almost entirely of females.It was proved from these evidences that the nagabuna and ginbuna with triploid state occur not only in the Kanto district but also in the Hokkaido district and Lake Biwa.These triproid females might be arisen by gynogenesis, as has been reported in the ginbuna obtained from the KantO district by Kobayasi (1971) and Kobayasi and Ochi (1972).

<p>The Indian mackerel <i>Rastrelliger kanagurta</i> is an important coastal fishery resource for Okinawa Prefecture, southwestern Japan. However, much is still unknown about its life history. The early development, occurrence, sexual maturation, and reproductive cycle of the species was examined from specimens collected from the coastal waters of Okinawa Island, and management of the fishery evaluated. Larvae [3.4 mm notochord length–12.5 mm standard length (SL)] and juveniles (11.4–16.2 mm SL) of <i>R. kanagurta</i> were distinguished from other mackerel species by: 1) numbers of myomeres, 2) absence of spines on the preopercle posterior margins, 3) positional relationship between the upper and lower jaw tips, 4) melanophore pattern, and 5) distribution (allopatric). Both larvae and juveniles occurred in the offshore epipelagic zone of Nakagusuku Bay in May, June, and August, which coincided with the occurrence of high-gonadosomatic value adults in coastal waters. However, specimens were not encountered in extremely shallow coastal areas (e.g., tidal flats), although younger individuals may utilize such the offshore epipelagic zone of the bay, attaining fork lengths (FL) of ca. 8 cm. Individuals mature at ca. 26 cm FL, one year after hatching. <i>R. kanagurta</i> are primarily caught by set net fishery near Okinawa, small (immature) individuals accounting for > 45% of netted individuals in all months, except May and June, during the period from April 1985 to April 1987, and for > 35% of the examined individuals in all months, except June and July, between April 2011 and March 2016. These results for both periods suggest growth overfishing. Accordingly, immature individuals must be conserved to sustain the Okinawan population of <i>R. kanagurta</i>.</p>

新たに日本産硬骨魚類6種 (マサバ, キハダ, マカジキ, イシダイ, コブダイ, ホテイウオ) の甲状腺を記載し, 更に他の資料を加えて, 硬骨魚類甲状腺の形状や組織構造について議論した。<BR>1.キハダとマカジキの甲状腺の形態は, 夫々既報のマグロとバショウカジキのそれに似ており, 腹動脈上, 第1, 第2入鰓動脈の分岐部に位置して, 前後両葉より成る緻密な軟塊である。<BR>この様な形態の甲状腺は, マサバ, マルソウダ, シイラ, ブリ, ヒラマサなどに見られる。<BR>2.イシダイとコブダイの甲状腺は, 前後両要素の区別が明瞭のまゝ一塊となつており, ホテイウオでは, 完全に一葉から成つている。これ等の事実は, 腹動脈より派生する入鰓動脈の状態に支配されているものと思われる。<BR>3.体重1kg当りの甲状腺重量は, マサバの9.00mgを最低に, ホテイウオの52.5mgを最大とし, 既報の4種を加えた10種類につき平均すると29.07mgとなる。<BR>4.本報した6種の魚類中, 機能亢進の甲状腺組織像を示したのはコブダイのみで, 他の5種はいずれも正常の活動状態にあつたと考えられる。塊状の甲状腺を有つ魚類では, 組織像のみによって機能の状態を正しく判断する事は困難である。
