A study on the life history of land-locked ayu <i>Plecoglossus altivelis</i> was made in Lake Ikeda, Kagoshima Prefecture, from 1981 to 1986.<br>Like amphidromous ayu, the life span of the land-locked fish in this lake is usually only one year and most of them die after spawning in autumn. However, a few individuals of land-locked ayu passing over the second winter are found in the lake.<br>The specimens counting 7, 810 of ayu in the lake were collected during this study and 73 of them were thought to be the over-wintered ones, because they had a conspicuous spawning mark on the embeded part of their scales. None of 0<sup>+</sup> fish had any such scales. The amounts of fat tissue around viscera of mature ayu decreased in the spawning season from early October to late Novermber. Also, the condition factor of ayu caught in November showed very wide range from 0.6 to 1.7. The fish whose condition factor was less than 0.9 had exteremely shrunk stomach without any food, whereas the fish of more than 1.3 in condition factor had normal stomach containing a small amounts of diatoms and blue-green algae. All specimens of 1<sub>+</sub> fish, which were collected after December, had recovered their fat tissue and begun to grow again. Thus, it is suggested that the survival of ayu after spawning season depends on the degree of stomach shrinkage and adequate intake of food. Some of them grew 150mm in standard length or more by the next autumn.<br>The specimens of mature 1<sup>+</sup> fish which were caught at a spawning ground in October suggests that some of the over-wintered ayu in the lake are able to attain maturity in second spawning season.

The carangid genus Decapterus Bleeker, 1851 is characterized by single finlets behind both the second dorsal and anal fins, no scutes along the anterior curved part of the lateral line, two low papillae on the shoulder girdle, and a well-developed adipose eyelid. Members of the genus are distributed in tropical to temperate areas of the Pacific, Indian and Atlantic oceans, and are commercially important food fishes. Four species (D. akaadsi Abe, 1958, D. kurroides Bleeker, 1855, D. smithvanizi Kimura, Katahira and Kuriiwa, 2013 and D. tabl Berry, 1968), characterized by a red caudal fin, are included in the red-fin Decapterus group. In 2016 and 2018, three specimens [216–304 mm in standard length (SL)] of D. kurroides, previously recorded from the Red Sea and east coast of Africa to the east coast of Australia and the Philippines, were collected from Kumano-nada, Pacific coast of Mie Prefecture, Japan. Additionally, a single specimen (191 mm SL) collected from Japanese waters in the East China Sea (west of Kyushu) in 2006 was also identified as D. kurroides. The specimens represent the first records of the species from Japanese waters, the Kumano-nada specimens being the northernmost record for the species. Decapterus kurroides is the most similar to D. akaadsi, but differs from the latter in the following characters: scutes more numerous on the straight part of the lateral line (30–32 vs. 26–29 in D. akaadsi), longer head (head length 29.9–33.0% SL vs. 26.7–30.1%) and longer snout-anus distance (55.8–60.4% SL vs. 51.2–54.6%) [measurements for both species modified from Kimura et al., (2013)]. Decapterus kurroides is also distinguishable from D. smithvanizi and D. tabl by having fewer cycloid scales on the curved part of the lateral line (45–52 vs. 54–62 in D. smithvanizi, 61–72 in D. tabl) and a deeper body (body depth 23.4–27.2% SL vs. 19.4–22.5%, 16.6–23.0%). A new standard Japanese name “Kitsune-akaaji” is proposed for D. kurroides.

The cosmopolitan genus Opistognathus Cuvier, 1816, characterized by unforked dorsal-fin spines, currently comprises 64 valid species, including Opistognathus variabilis Smith-Vaniz, 2009, described on the basis of 71 specimens and widely known from the Maldives, Andaman Sea, Indonesia, Philippines, Palau, Taiwan, Ryukyu Islands and Vanuatu. However, the Japanese record was based solely on an underwater photograph taken off Iriomote Island, Ryukyu Islands. A single example of the species, collected from Yonaguni Island, Yaeyama Islands, represents the first record of the species from Japan supported by a voucher specimen. Opistognathus variabilis closely resembles Opistognathus albicaudatus Smith-Vaniz, 2011 and Opistognathus castelnaui Bleeker, 1860 in having an elongate upper jaw, numerous longitudinal scales and similar body coloration, including 7–10 dark blotches along the dorsal-fin base. However, the former can be distinguished from O. albicaudatus by the poreless Y-shaped area dorsally on the head (vs. absent) and 9–11 procurrent caudal-fin rays (vs. 6–7), and from O. castelnaui by having 68–92 longitudinal scale rows (vs. 90–110), the dorsal fin deeper posteriorly (vs. similar depth along entire length), a single stripe on the upper jaw inner surface (vs. two), and seven or eight mid-lateral blotches along the body (vs. three or four irregular dark horizontal lines and/or dark reticulations laterally on body). The new Japanese standard name “Shishidama-ohkuchi-amadai” is proposed for O. variabilis.

A single specimen of a carangid fish, Alepes kleinii (125.1mm in standard length), was collected by a small set net at depths shallower than 8m off the northeastern Kadogawa Bay, Kadogawa-cho, Miyazaki Prefecture, Pacific coast of Kyushu Island, Japan. Alepes kleinii is distinguishable from its congeners by the following combination of characters: two rows of small conical teeth arranged irregularly in a narrow band on upper jaw but those on lower jaw in a single series, a diffuse dusky blotch present on upper margin of opercle, and straight part of lateral line starting behind below origin of second dorsal fin. The specimen represents the reliable record of the species from Japan.

In Japan, wa (和. he in Chinese) is still popular as an important tenet taught by Prince Shotoku in the Ancient Age. In this paper, the author tries to analyze the concept of he as it appears in Chinese and Japanese Buddhist texts (Especially Chinese Versions of the Buddhist Canons) and clarify its various meanings, some of which have been deeply influenced by Chinese thought. Since the time of Early Buddhism, Buddhists have fundamentally attached importance to unification and harmonious relations of the order. For example, the famous Dhammapada says, sukha sanghassa samaggi samagganam tapo sukho. Samaggi in this sentence was translated he (和) or hehe (和合) in China. This seems to be the most basic sense of he in Buddhism. Secondly, the idea of hejing (和敬), which relates with he mentioned above is also notable. This idea served as the base of the theory of six kinds of hejing (六和敬), which means harmonious behaviors in the six fields of body (身), speaking (口), mind (意), sila (戒), view (見), and benefit (利) in general. But it does not seem that this theory was formed before the occurrence of Mahayana Buddhism in the first century B.C. and widely prevailed all over the Buddhist world. Thirdly, there is the term of heyan-aiyu (和顔愛語. wagen-aigo in Japanese). This phrase is very popular in Japan. However, we can not find out any equivalent in the Sanskrit text of the Amitayus-sutra to heyan, that constitutes the most well-known idiom in one of the Chinese versions of it. Fourthly, we discuss the concept of heguang-tongchen (和光同塵) 50 Buddhism and the Concept of he (和, wa in Japanese) in East Asia (Kimura) originating in the Laozi. This was accepted in Chinese Buddhism in two ways, i.e., one positive, and the other negative. We can see one typical example of the positive usage of this idiom in the Great Concentration and Insight (Mohezhiguan.摩訶止観) by Zhiyi (538-597). The negative usage of it, in the expression butongqichen (不同其塵) appears in the Mahayana-nirvana-sutra translated by Dharmaksema. Lastly, the author investigates the relationship between these various meanings of he in East Asian Buddhism and the thought of he advocated by Prince Shotoku. Our conclusion is that Prince Shotoku tried to apply the Buddhist idea of samaggi to the secular society at large.

Ten carangid specimens belonging to the genus Selar, collected by small set net at Kadogawa Bay, Miyazaki Prefecture (eastern coast of Kyushu Island), Japan, were identified as Selar boops (Cuvier in Cuvier and Valenciennes, 1833), on the basis of scales in curved part of lateral line 22-24 and chord of the curved part of lateral line 2.2-2.7 times in straight part. These specimens represent first record of the species from Japan. Specimens are described and a new Japanese name "Teru-meaji" is proposed for the species.
