We compared morphometry and total swimming costs of wild, farmed (first-generation hatchery progeny of wild progenitors) and domesticated (seventh-generation progeny of the Norwegian aquaculture strain) juvenile Atlantic salmon (Salmo salar). Respirometry experiments were performed to assess total swimming costs of fish ranging in size from 4.0 to 16.1 g wet mass at a water temperature of 15 °C. Fish were subjected to flow conditions of low and high turbulence. Total swimming costs increased significantly with intensity of turbulence and were, on average, 1.4 times higher at high than at low t

Abstract:
Individual computations and social interactions underlying collective behavior in groups of animals are of great ethological, behavioral, and theoretical interest. While complex individual behaviors have successfully been parsed into small dictionaries of stereotyped behavioral modes, studies of collective behavior largely ignored these findings; instead, their focus was on inferring single, mode-independent social interaction rules that reproduced macroscopic and often qualitative features of group behavior. Here, we bring these two approaches together to predict individual swimming patterns

Abstract:
In situ swimming speed and swimming behaviour of dielly migrating planktivorous fish were studied at a 120-m-deep location. Acoustic target tracking was performed using a hull-mounted transducer and submersible transducers located on the sea bottom and free hanging in the water column. The original data displayed a relationship between distance to transducer and swimming speed. A simplistic smoother applied during post-processing, appeared to break this relationship. Target tracking thus provided robust results on in situ swimming behaviour throughout the water column. Swimming speeds of deep-

Seabass swimming behavior was investigated in a salt-marsh area located along the Atlantic coast north of La Rochelle, France. Seabass is a natural inhabitant of this coastal zone and is farmed there as well. During its 3rd year, seabass can move about either singly or in small groups. Swimming activity of single fish and fish in a group was studied using an acoustic telemetry recording system. This study demonstrates that swimming activity levels and patterns of this species are modified by a group effect. Single fish were mainly nocturnal and fish in a group adopted a diurnal activity rhythm

Abstract:
<i>Abstract</i>.—Based on previous investigations of flatfish swimming performance, three hypotheses regarding frequency distribution of body angles (pitch and roll) during periods of pelagic excursions and periods when the fish swim along the bottom were formulated and evaluated. A tagging experiment on Greenland halibut <i>Reinhardtius hippoglossoides </i>was made with archival tags (DST) recording body angles each 15 min together with ambient depth. A total of 19 tags were recovered, representing 80,000 h of recording. The paper shows that for periods when pelagic or demersal swimming behavior can be deduced from the depth trajectories alone, the angular spectra were consistent with the hypothesized patterns for pelagic and demersal phases, respectively. Based on this distinction, the percentage of pelagic occupancy was estimated for each month of the year. With almost no occurrences of vertical swimming positions, the common perception that Greenland halibut adopts such position during pelagic phases was rejected.

<em>Abstract</em>.—Fish ladder designs that pass adult sturgeons are poorly studied. This is partly due to difficulties associated with obtaining and testing large adults. To learn about behavior and swimming of sturgeons in fish ladder environments, we observed juvenile lake sturgeon <em>Acipenser fulvescens </em>to determine the type of ladder opening that fish passed best. We also constructed a short fish ladder (6% slope) using the best opening type and determined the general usefulness of the ladder design to pass juvenile lake sturgeon, pallid sturgeon <em>Scaphirhynchus albus </em>and shovelnose sturgeon <EM>S</EM>. <em>platorynchus</em>. Lake sturgeon swam upstream through orifice and vertical openings better than through surface weir or weir and orifice openings. Because 37% of the fish hit the orifice when swimming upstream, and also, sturgeon could be damaged passing downstream through an orifice, we focused on testing a ladder design with vertical openings. A side-baffle ladder design that created vertical openings that alternated from side to side showed promise at passing the three species of sturgeons. All lake sturgeons (<EM>N </EM>= 15), most pallid sturgeons (12 of 22 fish, 55%), and 1 of 3 shovelnose sturgeons ascended the side-baffle design. Also, all sturgeon species moved safely downstream in the side-baffle ladder by passively drifting tail-first. Mean velocity in side-baffle openings was 60–75 cm/s, so sturgeons could use prolonged swimming speed to swim upstream. Vertical openings were wide enough for fish to partially erect their pectoral fins, likely a critical factor for maintaining balance. Our observations suggest that a ladder for adults should have vertical openings, enable fish to swim continuously and not stop at cross-channel barriers, have resting areas, enable fish to safely drift downstream, and enable fish to swim upstream using prolonged swim speed. The study of juvenile sturgeon behavior and swimming ability can contribute to developing a fish ladder for adults. This approach to fish ladder development can be used for other species with large adults.

<em>Abstract.</em>—We examined the swimming performance and behavior of red snapper, <em>Lutjanus campechanus. </em>Our intention was to use this information toward developing a more efficient bycatch reduction device for use in the Gulf of Mexico shrimp trawl fishery. Using a Brett type swim tunnel, we found a significant effect of fish size and season on red snapper critical swimming speeds. For fish ranging between 6 and 17 cm standard length, critical swimming speeds ranged from about 35–70 cm/s, depending upon season. However, critical swimming speeds did not differ between day and night. This was an important observation since the majority of shrimp trawling in the Gulf occurs at night. We constructed and tested in the laboratory, a Vortex Generating Bycatch Reduction Device (VGBRD) that may prove useful in the shrimp trawl fishery. During behavioral tests during daylight, 79.2% of red snapper exited the VGBRD in an average of 4.1 min. However, during night-time tests, only 17.6% of red snapper exited the VGBRD in an average of 5.0 min. Behavioral tests revealed a strong negative phototactic response in dark adapted red snapper. We found that, during night-time tests when the VGBRD was illuminated with LED lights placed downstream of the exit, 96% of red snapper exited the device in 7.1 min. In color/ contrast choice experiments, red snapper unerringly associated with the dark colored (black or dark green) panel placed on the bottom of the experimental tank. In another set of experiments, we found that snapper displayed a strong optomotor response, i.e. the tendency to following and match speeds with a moving pattern. Illumination, color/contrast, and/or the optomotor response may improve bycatch reduction device performance.

There are many types of systems in both nature and technology that exhibit limit cycles under periodic forcing. Sometimes, especially in swimming robots, such forcing is used to propel a body forward in a plane. Due to the complexity in studying a fluid system it is often useful to investigate the dynamics of an analogous land model. Such analysis can then be useful in gaining insight about and controlling the original fluid system. In this paper we investigate the behavior of the Chaplygin sleigh under the effect of viscous dissipation and sinusoidal forcing. This is shown to behave in a simi

Abstract:
Recently, flexible matrix composite (FMC) actuators were demonstrated in a robotic fish for swimming. When actuated at a specific frequency in the experiments, the sinusoidal component of the thrust was eliminated, leaving only a constant thrust. This elimination of the sinusoidal component of the thrust is due to the hydroelastic tailoring of the tail stiffness with the actuation frequency. The FMC actuators are pressure-driven muscle-like actuators capable of large displacements as well as large blocking forces. The FMC actuators can also exhibit a large change in stiffness through simple va

Abstract:
Flow fields around an oscillating airfoil at the low Reynolds number region are extremely unsteady because the change direction of leading edge produces unsteady vortex motions. Studies of unsteady propulsion system of birds, insects, and fish are few and inconclusive. It has been noted that the unsteady fluid force plays an important role in biological flight. To evaluate the force correctly, it is necessary to know the unsteady properties determined from the vortex dynamics. The actual motion of a hand in swimming is obviously unsteady, and time-dependent fluid forces must be considered, bec

Abstract:
This study explores the average flow field inside and around stocked Atlantic salmon (Salmo salar L.) fish cages. Laboratory tests and field measurements were conducted to study the effects of biofouling and especially fish behaviour on the flow patterns around and through fish cages. Currents were measured around an empty and a stocked fish cage in a fjord to verify the results obtained from laboratory tests without fish and to study the effects of fish swimming in the cage. Fluorescein, a non-toxic, fluorescent dye, was released inside a stocked fish cage for visualization of 3-dimensional f
