    Mixed-species shoals of fishes were reported from various environments such as coral reefs and temperate lakes. The driving mechanism of forming mixed-species shoal can be either haphazard or a preferential choice by an individual. Here, we tested if jack mackerel Trachurus japonicus, a temperate marine pelagic fish, could choose a shoal composition using vision based on a choice experiment. Shoal preference of jack mackerel juveniles was evaluated by presenting shoals comprising one to four heterospecifics (half-lined cardinal Ostorhinchus semilineatus) out of four shoal members to the focal fish. When both conspecific and heterospecific shoals were presented to a single jack mackerel, the focal fish showed a preference for the conspecific rather than heterospecific shoal, indicating that they can choose a conspecific shoal based on the visual information. However, when a focal fish encountered both conspecific and mixed-species shoals including fewer heterospecifics (one out of four individuals), the latter was preferred. The result implies that jack mackerel can judge a preferable composition of shoal using visual information. The inclusion of fewer heterospecifics may be exploiting oddity effects, whereby minority species are exposed to relatively high vulnerability to predators, as well as resulting in reduced competition for food while maintaining predator vigilance in a shoal.

    Various animals perform nest cleaning behaviour for breeding and keeping the hygiene of their living environment. Some fishes are also known to clean the nest for breeding and parental care, but it is unclear whether they clean it under non-breeding conditions. This study investigated the shelter cleaning behaviour of frillfin goby (Bathygobius fuscus) during the non-breeding season. All individuals of both males and females removed unknown objects (fishing sinkers) from their shelter, whereas they did not move many sinkers in the feeding area located outside the shelter. Subsequent video observation showed that fish removed sinkers using their tail fin, snout, mouth, and pectoral fins. The results suggest that frillfin goby clean their shelter even under non-breeding conditions. Furthermore, this study found that they can use pectoral fins to move objects, just like other animals use their hands and forelimbs to do so, supporting the developmental relationship between digits and pectoral fins in terms of functionality.

    <title>ABSTRACT</title>
    Angling gear avoidance learning is a possible factor that contributes to the vulnerability of caught-and-released fish to angling. Whereas past studies suggested angling gear avoidance learning, they were based on large-scale experiments on groups of fish and unable to verify learning accurately. Details of avoidance learning are also unclear. The present study investigated angling gear avoidance learning through a series of individual-based experiments using red sea bream (Pagrus major) juveniles. Fish avoided angling gear after only one or two catches while showing feeding motivation for pellets, representing avoidance learning for angling gear. Most of the experienced fish avoided krill attached to a fishing line, but not krill alone or pellets presented near the angling gear. Experienced fish were less vulnerable to angling than control fish. Approximately half of the experienced fish kept the memory of angling gear 2 months after learning. The learning effect through the catch-and-release procedure would reduce catchability and the value of fishery-dependent stock assessments.

    © 2019 Elsevier Ltd Apostichopus japonicus (Japanese sea cucumber) is of ecological and economic importance in the coastal waters of Japan. To assess the apparent abundance of A. japonicus, density data of visible A. japonicus are required; however, the activity of this species on the sea floor changes with variations in sea water temperature. For example, at high sea water temperatures, A. japonicus takes shelter in the gaps of rocks or oyster shells. This change in its visibility on the sea floor makes it difficult to determine the apparent abundance of this species. In the present study, we aimed to clarify the optimal survey timing to assess the apparent abundance of A. japonicus based on the relationship between the density of visible A. japonicus and sea water temperature. Between 2010 and 2013, we evaluated how the density (ind. 100 m−2) of visible A. japonicus changes with sea water temperature in an area preferred by these organisms, Maizuru Bay, Kyoto, Japan, every 2 weeks. Seasonal changes in the density were consistent with seasonal variations in sea water temperature. Density increased when sea water temperature decreased and was at a maximum at minimum sea water temperatures. In addition, the density tended to change significantly over a short period. In some cases, the density after the lowest sea water temperature in March 2011 declined by half from 65 to 27 in just 2 weeks. Owing to considerable variations in the density of visible A. japonicus, we believe it is important to establish the appropriate survey timing to quantify the apparent abundance of this species, with our data suggesting that surveys should be performed during the season with the lowest sea water temperatures. Furthermore, at the lowest sea water temperatures in 2010, 2011, 2012, and 2013, the maximum densities were 99.0 (9.1 °C), 65.0 (9.7 °C), 41.3 (9.8 °C), and 8.7 (8.9 °C), respectively. Over 4 years, the density decreased to approximately 10% of that in the year with the peak density. Considering this decrease, it is suggested that A. japonicus in Maizuru Bay is overfished. Therefore, it is possible that the density of visible A. japonicus at the lowest sea water temperatures provides useful information for assessing the apparent abundance of this species.

    © 2019, Japan Ethological Society. Habitat preference is thought to be genetically programmed in fishes. However, fishes can choose habitat based on their personal experience of an environment. We investigated whether the environment in which fish are raised affects habitat preference in red sea bream Pagrus major juveniles, and tested if the formed preference lasts until later life stages. Juveniles were reared in tanks with a substrate of either sand or artificial seaweed for 40 days. Naive fish were raised without either type of substrate. In the preference test, individual fish were allowed to choose either a sand or artificial seaweed microhabitat. The tested fish were then kept in barren tanks, and similar tests conducted again on days 30 and 100. Sand and seaweed treatment fish preferred the corresponding habitat immediately after the rearing treatment, whereas naive fish did not exhibit any preference. These preferences were maintained when fish were tested on day 30, but not on day 100. The present study suggests that habitat preference is acquired through the rearing environment at the nursery stage, and that this preference lasts for at least 30 days. The formation of habitat preference should help juveniles to choose an optimal microhabitat in a fluctuating environment.

    The Japanese sea cucumber Apostichopus japonicus plays important ecological and economic roles in the coastal areas of Japan. Here, we aim to reveal the relation between habitat characteristics and density of juvenile and adult sea cucumbers in Maizuru Bay. Density of adult sea cucumbers was estimated by underwater visual surveys and bottom trawls and that of newly settled individuals by seedling collectors distributed in the bay. The physical environment of the sea bottom was evaluated from median diameter, total organic carbon, total nitrogen, carbon-to-nitrogen ratio, carbon isotope ratio, nitrogen isotope ratio, depth, slope, and distance from the coastline. Adult sea cucumber density was higher in the east side than the west side of Maizuru Bay, the former having a no-take zone for sea cucumbers. Juvenile sea cucumbers were most abundantly collected in the central part of the bay. High organic matter from the sea, short distance from the coastline, and high seabed gradient (steepness) had a positive effect on the density of adult sea cucumbers, and depth had positive effects on their body size. We suggest that sustainable management of sea cucumbers can be achieved by a combination of the establishment of no-take zones and increased protection of nursery habitats.

    The low return rate of fish released for stock enhancement has often been attributed to hatchery-reared fish having inferior behavioral characteristics. We tried to improve the behavioral characteristic of red sea bream (Pagrus major) juveniles by using a net-chasing treatment. The fish were provided with 2 min of net chasing twice daily for 3 weeks, following which their behavioral characteristics (emergence from a start area, avoidance response to novel stimulus, and foraging following transfer between tanks) were individually tested and compared with a control group. A predator exposure test was then conducted using marbled rockfish (Sebastiscus marmoratus). Net-chased fish exhibited a shorter latency to emergence, a higher avoidance rate, and an earlier foraging time than the control fish, indicating that the net-chasing treatment may improve adaptability for environmental change and alertness to a novel object. The net-chased fish also exhibited a better survival rate than the control fish, with an odds ratio of 6.76. We suggest that net-chasing training represents an easy and efficient method for improving the behavior of fish for stock enhancement.

    We aimed to confirm the reproduction of Manila clam Ruditapes philippinarum in Maizuru Bay, and also determine the cause of their mortality. Using seedling collectors, we obtained 5 to 60 juveniles per collector, demonstrating that this species is reproducing in the bay. Depletion of clams in Maizuru Bay was investigated by setting clams on coastal area sea beds in the summer. Predation was found to be more effective in depleting clams than environmental factors. Laboratory experiments revealed that juveniles less than 5 mm in shell length were preyed upon by 6 out of 13 fish species, whereas Japanese rock crab preyed upon clams from juveniles to adults.

    Recent studies in streams and ponds have demonstrated that the distribution and biomass of aquatic organisms can be estimated by detection and quantification of environmental DNA (eDNA). In more open systems such as seas, it is not evident whether eDNA can represent the distribution and biomass of aquatic organisms because various environmental factors (e.g., water flow) are expected to affect eDNA distribution and concentration. To test the relationships between the distribution of fish and eDNA, we conducted a grid survey in Maizuru Bay, Sea of Japan, and sampled surface and bottom waters while monitoring biomass of the Japanese jack mackerel (Trachurus japonicus) using echo sounder technology. A linear model showed a high R-2 value (0.665) without outlier data points, and the association between estimated eDNA concentrations from the surface water samples and echo intensity was significantly positive, suggesting that the estimated spatial variation in eDNA concentration can reflect the local biomass of the jack mackerel. We also found that a best-fit model included echo intensity obtained within 10-150 m from water sampling sites, indicating that the estimated eDNA concentration most likely reflects fish biomass within 150 m in the bay. Although eDNA from a wholesale fish market partially affected eDNA concentration, we conclude that eDNA generally provides a 'snapshot' of fish distribution and biomass in a large area. Further studies in which dynamics of eDNA under field conditions (e.g., patterns of release, degradation, and diffusion of eDNA) are taken into account will provide a better estimate of fish distribution and biomass based on eDNA.

    Japanese rock crab Charybdis japonica is a major predator forManila clam Ruditapes philippinarum and so the development of countermeasures against this predation would help restore the decreased clam resource. Choice experiments revealed that C. japonica approaches clams by using olfactory cues, and thus can nd clams that have burrowed into sand. Laboratory conditions that either disturbed sensory cues or provided cover failed to show any improvement in the survival of clams. However, eld trials in Maizuru Bay demonstrated that sparging small stones is ecient for improving the survival of clams.

    本研究は、“サカナ”が持っている心理特性である「情動」に注目し、摂食行動の基盤にある摂食情動を摂餌音および赤色光刺激によって促進させることで、飼育魚の成長効率の向上を目指すことを目的とする。初年度である2022年度では、摂餌音の確認および録音・再生システムの構築を実施し、同時並行で赤光の摂食情動促進効果について検討した。水産有用魚種に適用する前に、モデル生物であるゼブラフィッシュを対象に、摂餌音・赤色刺激の実験を実施した。摂餌音については、水槽下でのゼブラフィッシュの摂餌時に特徴的な周波数の摂餌音が確認され、摂餌音の録音・再生システムを構築することができた。また、赤光刺激については、ゼブラフィッシュの摂餌行動は、赤光環境下で活発な摂餌が持続しやすい効果が確認された。水産有用種での検討では、マアジを用いて赤光が摂餌行動におよぼす効果について検討をした。赤光の照射によってマアジの摂餌量の増加効果は確認されなかったが、水面下での遊泳行動の増加効果は確認されたことから、赤光は摂餌活性を高める可能性が示唆された。
