“…Home range areas were 2.0-14.0 hectares, and core areas were 0.8-6.0 hectares. Hockin et al (1989) described the use of three primary areas by grass carp in a British canal, and indicated that fish moved quickly between these areas. Cassani and Maloney (1991) described two general behavior patterns, free-ranging activity and home area use, and reported that seven of nine fish tracked established use of a home range for some period during their study.…”

“…Maximum distance moved by a grass carp from the site of stocking and distances between consecutive radio locations of an individual grass carp were calculated as straight line movements, and are considered minimum distances (Hockin et al 1989;Cassani and Maloney 1991). Based on the above measures of movement, we defined percent maximum distance moved as the maximum distance moved by a fish from its stocking site divided by the distance from that stocking site to the most distant point in the lake, and movement rate as the distance moved by each fish over the course of the study (sum of distances moved between consecutive radio locations) divided by the time that fish was tracked.…”

“…Some studies of grass carp movement and behavior have been conducted, but most of this work took place in small (< 100-hectare) lakes (Mitzner 1978), in canal systems (Hockin et al 1989;Cassani and Maloney 1991) or reservoir systems (Bain et al 1990), or for short (<30-d) periods (Nixon TR1PLOID GRASS CARP MOVEMENTS IN LARGE LAKES and Miller 1978). Comparatively little research has been conducted to answer questions concerning the movement and long-term behavior of triploid grass carp in large, natural lakes.…”

A radiotelemetry study was conducted to qualitatively and quantitatively describe movement and aquatic plant selection by triploid grass carp Ctenopharyngodon idella in two types of Florida lakes, one open system with little submerged aquatic vegetation (Lake Harris) and one closed system with extensive submerged aquatic vegetation (Lake Yale). Nineteen fish were successfully tracked for between 38 and 546 d. Median maximum distance moved from site of stocking was significantly different for fish in the two lakes (10.4 km for fish from Lake Harris and 3.7 km for fish from Lake Yale), but median percent maximum distance moved was not. Median movement rate was 155 m/d for Lake Harris fish and 126 m/d for Lake Yale fish; these values were not significantly different. Corrected home range areas for Lake Harris fish ranged from 61 to 4,954 hectares (median, 3,021 hectares), and for Lake Yale fish from 159 to 594 hectares (median, 378 hectares). Radio‐tagged fish did not move through any of the navigable waterways connecting Lake Harris to other lakes in the Harris Chain. Lake Yale grass carp used the target plant, hydrilla Hydrilla verticillata, disproportionately to its abundance in the lake, and were located in shoreline emergent vegetation on fewer than 10 occasions. There was little variation in use of plants by grass carp in Lake Yale during the first versus second half of the study, but there was some evidence of seasonal variation. Lake Harris fish were primarily found in association with littoral vegetation communities, or in canal or riverine environments. These were the only areas in Lake Harris that contained appreciable amounts of submergent aquatic vegetation. Triploid grass carp have the potential to cover the majority of a lake from a single stocking site, but, where plants are present in abundance, the fish can be expected to feed in areas from 250 to 750 hectares in size.

Seasonal distribution of adult crucian carp nigorobuna Carassius auratus grandoculis and gengoroubuna Carassius cuvieri in Lake Biwa, Japan

Seasonal habitat use by nigorobuna Carassius auratus grandoculis Temminck et Schlegel and gengoroubuna Carassius cuvieri (Temminck et Schlegel) in Lake Biwa was investigated using acoustic telemetry. Twentythree nigorobuna and 11 gengoroubuna specimens caught using set-nets in the lake's south basin were surgically fitted with acoustic transmitters and then released. Signals from the fishes were recorded by 23 receivers installed around the lake. Between April and June 2007, the first spawning season after release, signals were received from all tagged fishes. Thereafter, until the second spawning season, signals were collected from 26 and 45% of released nigorobuna and gengoroubuna individuals, respectively. Seasonal habitat preferences for these species were studied by distance-based analysis. The analysis revealed that nigorobuna tended to stay near their spawning area in the south basin of the lake throughout the year, whilst gengoroubuna tended to show a seasonal migration pattern between the north and south basins. After the spawning season, the latter species migrated to the north basin where it remained until the next spawning season, when it returned to the south basin. This is the first report of seasonal migration of nigorobuna and gengoroubuna in Lake Biwa.

“…Data are somewhat mixed in terms of diurnal movements. Experiments conducted in a small canal in Great Britain suggested that grass carp may move during the entire 24 h day (Hockin et al, 1989). Movements were greatest around dawn, and elevated activity levels persisted until midday.…”
