“…In other words, respiration increased more rapidly than cell growth at high temperature, causing a reduction in NGE. Thus, GGE would decrease with temperature unless AE increased appreciably (Malloy & Targett 1991). In contrast to the negative correlation for ciliates, there is a positive relationship between GGE and temperature for nano-and microflagellates and no significant relationship for rotifers (Straile 1997).…”

Condylostoma is as a group of very large-sized ciliates frequently dominant in various marine benthic microbial communities. However, little is known about the effects of temperature and food concentration on its growth and grazing. Here, using the heterotrophic dinoflagellate Oxyrrhis marina as prey, we determined the specific growth rate, cell volume, specific production, and ingestion rate of C. spatiosum at different temperatures and prey concentrations. These growth and grazing parameters typically followed a hyperbolic response to prey concentration. By applying iterative curve-fitting to the data at each temperature, we found that, with increasing temperature, the maximum specific growth rate, maximum specific production, and maximum ingestion rate of C. spatiosum generally increased, while the maximum cell volume decreased. The gross growth efficiency of C. spatiosum generally decreased at saturated prey concentration from about 45 to 25% as the temperature increased from 12 to 24°C. By fitting these data iteratively to multi-variable nonlinear models, we obtained predictive equations for the growth rate, cell volume, and ingestion rate with respect to temperature and prey concentration.

In order to gain a better understanding of the effects of temperature and prey concentration on benthic ciliate population dynamics, we investigated the growth and grazing responses of C. spatiosum feeding on O. marina at a range of temperatures and food concentrations. Based on the data obtained, we developed predictive models that will allow us to estimate the growth and grazing rate of C. spatiosum within given ranges of temperature and food concentration. MATERIALS AND METHODSStudy organisms. The size of the ciliate Condylostoma spatiosum was on average 700 × 80 µm (n = 20) and the dinoflagellate Oxyrrhis marina was on average 29 × 16 µm (n = 20) in vivo. Both species were isolated from the intertidal sediment of the Licun River estuary at Qingdao, China, in July 2007 and were maintained in Petri dishes containing bacterized rice-grain medium at room temperature.Experimental design. Experiments were run in Petri dishes (diameter 90 mm) in dim light (1.2 to 2.0 µmol m -2 s -1) under a 12 h light:12 h dark cycle. The experimental volume in each plate was 20 ml. Ciliates were taken from the exponential growth phase and were adapted to the experimental temperature and prey concentration for at least 24 h before the beginning of the experiments.Growth and ingestion experiments were run separately at the temperatures of 12, 15, 18, 21, and 24°C. Each treatment was conducted with 20 prey concentrations ranging from about 8 × 10 2 to 1.3 × 10 4 cells ml -1 (corresponding to 0.21 t...

“…The growth rates found in our study were lower than the values in Wakasa Bay and Igarashihama. For Paralichthys species, growth rate is affected by the amount of food (Tanaka et al 1994), temperature (Seikai et al 1986, Malloy & Targett 1991, and size of fish (Kusakari & Mori 1982, Kramer 1991. Compared with the results of Tanaka et al (1994), the lower temperature and larger size of flounder in this study in addition to transient stunting seem likely to be responsible for lower growth rates of released flounder on the Iwate coast.…”

A total of 35900 in 1990 and 73400 in 1991 otolith-marked, hatchery-raised Japanese flounder Paralichthys olivaceus fry ranging from 4 to 15 cm total length (TL) were released into shallow water at depths of 4 to 8 m at Ohno Bay, northeastern Japan. The otoliths of the fish were marked 1 to 3 d prior to release with an alizarin complexone fluorescent marker The size at release of flounder recaptured by a beam trawl, set net and commercial catch was estimated using the fluorescent mark diameter to TL relationship, and survival and growth rates were examined. As time progressed after release, back-calculated release size distributions gradually shlfted to larger values. The flounder fry > 9 cm at release were successful in recruiting to commercial fisheries. The major cause of mortality was thought to be predation by large flounder and greenling Hexagrammos otaku whlch were abundant in the flounder nursery ground. Growth rate of released flounder was high in the warm and low in the cold season. Individual growth rates were estimated by otolith mark diameter and TL at catch. The relationship of release size and growth rate analyzed in the flounder recaptured 1 1 mo after release indicated that survival of released flounder is strongly associated with size itself and growth rate in the field.

“…Summer residence in estuarine waters is an important component of P. dentatus growth and survival. Fast estuarine growth of YOY , Szedlmayer et al 1992 occurs in response to appropriate temperature and food availability, according to laboratory studies (Peters & Angelovic 1973, Malloy & Targett 1991, 1994. Thus, it is important to identify the essential components of habitat use during this important growth season in estuarine waters, especially since these waters are frequently impacted by anthropogenic sources (Able 1999, Hoss et al 1999, Quinlan & Crowder 1999.…”

A comprehensive understanding of habitat use for economically and ecologically important species in estuaries is lacking. This research, based on passive and active ultrasonic telemetry, focuses on temporal and spatial patterns of juvenile and adult (length = 268 to 535 mm) summer flounder Paralichthys dentatus habitat use during years, seasons, tides, and diel periods from 2003 to 2005 in the Mullica River-Great Bay estuary in southern New Jersey, USA. Annual site fidelity was demonstrated by tagged fish that returned to the study estuary and frequented locales within 550 m or less of the sites where they were located in previous year(s). Fish resided within the estuary for a mean of 86 d (range: 1 to 217 d) during summer 2004, the year of the most comprehensive tracking. Fish primarily utilized the lower bay, close to the ocean inlet. Several more mobile individuals moved along the channel of the Intracoastal Waterway in Great Bay numerous times in a single season, while others moved up the bay and into the river in a year when salinity was higher than average. Tagged fish typically used deeper areas of the estuary correlated with high, stable levels of dissolved oxygen (DO) and temperature. Over diel and tidal periods, fish resided within small (0.18 km 2 ) areas for 3 to 6 h but were in motion 74% of that time. Together, these observations indicate habitat-use patterns that are stable over long periods (years) but dynamic within shorter time periods (seasons, hours).
