Characterization and evaluation of sex-specific expression of suppressors of cytokine signaling (SOCS) -1 and -3 in juvenile yellow perch (Perca flavescens) treated with lipopolysaccharide. Fish and Shellfish Immunology. 33:468-481. Interpretive Summary: Yellow perch are highly prized as a recreational and food fish. The strong demand for yellow perch in the Midwest traditionally has been met by a commercial wild-capture fishery. Recent declines in wild stocks of the Great Lakes region of the U.S. and Canada, and restrictions on capture fisheries, have fueled the need for aquaculture production as a means to meet increasing demand for yellow perch. However, expansion of yellow perch aquaculture has been limited by the slow growth of this species in aquaculture settings. Additionally, growth in yellow perch is sexually-dimorphic wherein females grow larger and faster than males; such size discrepancies pose further difficulties ...
Fish consumption is a potential route of human exposure to the hepatotoxic microcystins, especially in lakes and reservoirs that routinely experience significant toxic Microcystis blooms. Understanding the rates of uptake and elimination for microcystins as well as the transfer efficiency into tissues of consumers are important for determining the potential for microcystins to be transferred up the food web and for predicting potential human health impacts. The main objective of this work was to conduct laboratory experiments to investigate the kinetics of toxin accumulation in fish tissue. An oral route of exposure was employed in this study, in which juvenile yellow perch (Perca flavescens) were given a single oral dose of 5 or 20 μg of microcystin-LR (MC-LR) via food and accumulation in the muscle, liver, and tank water were measured over 24 h. Peak concentrations of the water soluble fraction of microcystin were generally observed 8-10 h after dosing in the liver and after 12-16 h in the muscle,
Primarily age and body size determine the diets of yellow perch. Zooplankton is the primary food source for young and larval perch. By age one, they shift to macroinvertebrates, such as midges and mosquitos. Large adult perch feed on invertebrates, fish eggs, crayfish, mysid shrimp, and juvenile fish. They have been known to be predominantly piscivorous and even cannibalistic in some cases. About 20% of the diet of a yellow perch over 32 grams (1.1 oz) in weight consists of small fish. Maximum feeding occurs just before dark, with typical consumption averaging 1.4% of their body weight.[3]. Their microhabitat is usually along the shore among reeds and aquatic weeds, docks, and other structures. They are most dense within aquatic vegetation, since they naturally school, but also prefer small weed-filled water bodies with muck, gravel, or sand bottoms. They are less abundant in deep and clear open water or unproductive lakes. Within rivers, they only frequent pools, slack water, and moderately ...
The climbing perch, Anabas testudineus, inhabits large rivers, canals, stagnant water bodies, swamps and estuaries, where it can be confronted with aerial exposure during the dry season. This study aimed to examine nitrogen excretion and metabolism in this fish during 4 days of emersion. Contrary to previous reports, A. testudineus does not possess a functional hepatic ornithineurea cycle because no carbamoyl phosphate synthetase I or III activity was detected in its liver. It was ammonotelic in water, and did not detoxify ammonia through increased urea synthesis during the 4 days of emersion. Unlike many air-breathing fishes reported elsewhere, A. testudineus could uniquely excrete ammonia during emersion at a rate similar to or higher than that of the immersed control. In spite of the fact that emersion had no significant effect on the daily ammonia excretion rate, tissue ammonia content increased significantly in the experimental fish. Thus, it can be concluded that 4 days of emersion caused ...
Using stable isotopes of carbon (δ13C) and nitrogen (δ15N), I investigate the trophic ecology and niche overlap of Yellow Perch (Perca flavescens) and White Perch (Morone americana) across the western basin of Lake Erie. Stable isotopes varied spatially and temporally in lower trophic level organisms, which are used to estimate carbon sources and trophic position of consumers. These variations inhibit our ability to assess trophic relationships, particularly in large lakes. Yellow Perch relied on benthic food sources, while White Perch occupied higher trophic positions and had larger niche widths. Trophic positions of yellow and white perch were related to size however a lack of δ13C- length relationship suggests these species exhibit no changes in carbon source. Significant differences in δ 13C/ δ15N and high niche overlap among Yellow and White Perch indicated that the species are utilizing different forage bases, however, have the potential to compete if resources become limited.

I have a small pond that has a very limited population of yellow perch in it. These fish are offspring of fish I stocked from a local lake. Nearly every fish I catch in that small pond has worms as we call them, but I guess the proper name is some sort of parasite. They look like a small tan colored cyst in the flesh when filleted, but can also be seen through the skin around the lower jaw and gills. Are these a treatable ailment or is this just something common to perch in warm water? I fillet them out and often fry fish with them in the meat, never worried about it, but I have considered stocking some of the smaller fish in my new larger pond, just wondered if these were an inevitability in my new pond regardless of measures I take to stop them? Obviously I would prefer not to have them if I could. Anyone else seen these ...

The Trout-perch Percopsis omiscomaycus (Walbaum) is a widely distributed species in North America, yet they present a number of puzzles. Percopsis means "perch like" (Greek, perke=perch and opsis=appearance) and omiscomaycus is an Algonkian name that includes the root word "trout." This enigmatic fish is certainly not a trout - though it has an adipose fin and a scaleless head -- and certainly not a perch - though its coloration and spines are somewhat similar. It has traits that are characteristic of each group. For example, the dorsal fin has 2 weak spines and pelvic and anal fins each have one weak spine. And the scales are ctenoid with a single row of teeth on the edge. But, there is that puzzling adipose fin. The head is large and the premaxillary bones are nonprotractile, unlike the Yellow Perch Perca flavescens. Trout-perch are ray-finned fish in the Class Actinopterygii (ACK-tih-NOP-tuh-RIJ-ee-eye). They are a surviving remnant of mostly marine fish that marked the transition between ...
A previously unknown microsporidian parasite that severely degrades muscle of yellow perch (Perca flavescens) from lakes in Minnesota, Wisconsin, and Lake Ontario was identified as belonging to the genus Heterosporis. This parasite is characterized by pyriform-shaped spores that are contained in sporophorocysts. In the wild, yellow perch, burbot (Lota lota), mottled sculpin (Cottus bairdi), trout-perch (Percopsis omiscomaycus), pumpkinseed (Lepomis gibbosus), northern pike (Esox lucius), walleye (Sander vitreus) and rock bass (Ambloplites rupestris) harbor Heterosporis naturally, but laboratory studies showed that 12 other fish species are susceptible to infection. In laboratory trials, smallmouth bass (Micropterus dolomieui) consumed significantly more fathead minnows infected with Heterosporis sp. than uninfected. Microscopically, Heterosporis sp. infection can be detected in the muscle of fish two weeks after exposure, and visually identified after seven weeks. To confirm infection, a PCR ...
A 96 hours acute toxicity test was completed in order to determine paraquat lethal concentration 50% (96H LC50) value towards Anabas testudineus. The fish was subjected to 0, 5, 10, 20, 30 and 40 mgL-1
The combined effect of Vitashield 40EC (chlorpyrifos ethyl-CPF) and Bassa 50EC (fenobucarb-F) was compared with the effects from exposure to the two pesticides separately, by measuring the brain acetylcholinesterase (AChE) activity in climbing perch fingerlings (Anabas testudineus). The experiment was conducted under controlled laboratory conditions and included three treatments containing 0.173 mg/L of CPF, 1.137 mg/L of F, 0.173 mg/L of CPF + 1.137 mg/L of F (M), and a control. The inhibition of the brain AChE activity in fish exposed to F was weaker and shorter than in fish exposed to CPF. The inhibition by the mixture of CPF and F was significantly lower and less prolonged than the inhibition by only CPF but significantly higher than the inhibition by only F.. ...

B.1. INTRODUCTION. The Nile perch (Lates niloticus),2 was reportedly transplanted into the Ugandan waters of Lake Victoria in the late 1950s and early 1960s (EAFFRO 1960; Hamblyn 1960).3 The question of whether or not to introduce this large, predatory fish sparked considerable controversy (Anderson 1961; Fryer 1960; Jackson 1971; Ogutu-Ohwayo 1985; Ribbink 1987; van Someren 1963). Opponents pointed out that such a step made little ecological sense: the theoretical potential sustained harvest from predatory fish (at the top of the food/energy pyramid) is significantly less than from their prey (typically represented at the middle or lower levels of the pyramid). Others argued that Nile perch, feeding on the huge but relatively unexploited and unpopular species stocks of haplochromine cichlids, would eventually provide the Lake with an important new fishery. Indeed, certain reports give the impression that Lates was first introduced with just such an objective in mind (e.g. Acere 1985). However, ...

In the middle and lower depths of our lakes in winter, a region of 39 degree water prevails, providing a haven for those fishes that remain active throughout this season. (A noteworthy physical property of water is that it becomes most dense at 39 degrees and sinks to the bottom. As water cools further, it becomes less dense or lighter in weight and rises to the surface. As a given mass solidifies, its density decreases even further, which is why ice floats on the surface rather than sinks.) While 39 degree water causes rapid hypothermia in humans, it is within the lower range of thermal acceptability for various species of cold-blooded organisms, including a favorite of winter anglers- the yellow perch.. The yellow perch, known to most as simply a perch, is a thick-scaled fish with noticeable vertical streaks on its sides and two separate dorsal fins. The first dorsal fin is supported by sharp-pointed spines that make the perch a challenge to handle without experiencing a painful poke to the ...

THIS REPORT is based on several years of intensive studies of the production and related population dynamics of six kinds of warmwater fishes maintained as single species in 1-acre ponds. Species involved included the largemouth bass, Micropteriis salmoides (Lacepede); smallmouth bass, M. dolomieiii Lacepede; bluegill, Lepomis macrochiriis Rafinesque; yellow perch, Perca flavescens (Mitchill); brown bullhead, Ictahiriis uebulosus (LeSueur); and the white crappie, Pomoxis annularis Rafinesque. Most production data published for these species have originated primarily from studies involving complex, multispecies populations. The principal aims of this investigation were to 1 ) increase our knowledge of the carrying capacities of ponds for warmwater fishes, 2) consider the relationship of carrying capacity to standing crop and to rate of production, and 3) measure the influence of controlled population increases and decreases on fish production ...

An estimated one-third of all known snail darters, an endangered three-inch fish that has halted construction of a $116 million Tennessee Valley Authority dam, were killed Tuesday in a freak accident that experts suspect may have involved contamination of a fish net with an insecticide.. Ninety-eight of the estimated total population of 300 darters died a mysterious death Tuesday night as the TVA, bowing to a Fish and Wildlife Service order, was transferring some the controversial fish back to their breeding ground in shallow water above the Tellico Dam.. The Fish and Wildlife Service had insisted the darters would become extinct unless the TVA moved them upriver to their breeding grounds. This had to be done manually because the fish cant fight the current created by the still unclosed dam gates on the Middle Tennessee River. The dam has been halted pending Supreme Court review of the case, by a Sixth U.S. Circuit Court of Appeals order that accused the TVA of violating the Endangered Species ...
The Lake Erie Center at the University of Toledo has been awarded a $209,126 federal grant to study a deadly fish disease that has threatened the health of many species of Great Lakes fish.. The grant, announced yesterday by U.S. Rep. Marcy Kaptur (D., Toledo), will fund a two-year study into viral hemorrhagic septicemia, or VHS.. It is an infectious viral disease present in several species of fish in the Great Lakes, including all-important walleye and yellow perch.. VHS has been responsible for several fish kills in the Great Lakes, including a kill of thousands of freshwater drum, or sheepshead, and yellow perch in central Lake Erie in the summer of 2006.. It is regarded by government biologists as the most dangerous fish virus in the world, though it poses no harm to humans.. For the first time, VHS recently was confirmed in fish beyond the Lake Erie watershed in inland Ohio - among muskellunge at Clear Fork Reservoir near Mansfield.. No fish kill has been recorded there to date, but state ...
Larval parasites within paratenic hosts rarely grow; likewise larval stages in intermediate hosts frequently stop growing before their growth is compromised by limited host resources and enter a stage of growth arrest. At this stage, the parasite may become encapsulated, which as an evolved strategy can reduce their mortality rate [43]. Encapsulation, however, is mutual adaptation between the hosts immune response and parasite, reaching a strategic compromise between the two to ensure the survival of both species [19]. The various life strategies employed by parasite species can influence different aspects of host physiology and so activate different immunological pathways [44]. The manner in which mammalian muscle responds to encapsulating species of nematode like Trichinella spiralis (Owen, 1835), for example, which elicits an inflammatory reaction, is different to that of non-encapsulating species of nematode like Trichinella pseudospiralis Garkavi, 1972, [19]. During infection with T. ...

Perch are popular sport fish species. They are known to put up a fight, and to be good eating. They can be caught with a variety of methods, including float fishing, lure fishing and legering. The best way is to use a small hook and cast into the weeds just before the drop off. When fishing with bait, the angler will want to have a disgorger; perch are notorious for swallowing the hook, and will need aid of a disgorger or forceps for unhooking. In many parts of the world, they are also a favourite species among ice fishermen. They will take a variety of baits, including minnows, worms, maggots, goldfish, pieces of raw bacon, prawn, and softshell crayfish, but seem to prefer shrimp (Caridina, Neocaridina, Palaemon), Krill, small fish, lobworms, ragworms, red maggots, and lures. Fly fishing for perch using patterns that imitate small fry or invertebrates can be successful. The record weight for this fish in Britain is 6 lb 3 oz (2.81 kg), and in America 6 lb 4 oz (2.83 kg).. Perch grow to around ...
Perches are another necessity in keeping healthy finches. There must be a variety of perches with different shapes and textures in the cage since they spend most of their time on them. There are several types of perches available to finches. Manzanita branches are a common form of a perch used by most owners. It provides a natural look in the cage and it comes in a variety of sizes and structures. A manicure perch is often utilized for its perfect diameter size and for its ability to trim nails with ease. Soft rope perches are another type preventing callused feet. Try to stay away from sandpaper perches because they may often cause pressure build-up and sores on their feet. Provide as many different types of perches as possible to keep the finch happy and healthy. Place them away from food or water dishes to avoid contamination and sickness from any fecal matter. The more variety of perches in the cage the healthier the finch will be ...
