Yellow perch, Perca flavenscens, is a sportfish found throughout the Great Lakes region and highly valued for its high-quality, firm, white, flaky flesh (Hinshaw 2006). A commercial fishery established for yellow perch yielded as high as 37 million pounds through the 1950s and ’60s but nearly collapsed shortly thereafter (Scott and Crossman 1973). In response, commercial yellow perch harvest became prohibited except for Lake Erie and Green Bay of Lake Michigan. In 2008, the estimated commercial yellow perch harvest from the Great Lakes was 8.33 million pounds. Despite the major decline in commercial harvests, demand for yellow perch as a food fish has remained high for over 30 years (Riepe 1998). As early as the 1970s, researchers at the University of Wisconsin-Madison became interested in culturing/farming the species (Hart et al. 2006). Initial research showed that yellow perch had characteristics that made them a favorable candidate species for commercial aquaculture:
- They readily accepted a pelleted fish food.
- They handled crowding, handling, and water quality degradation with little impact to growth.
- They did not exhibit cannibalistic behaviors at high densities.
- There were no detectable issues with the flavor of fish cultured in ponds and tanks (Hart et al. 2006).
There are challenges associated with the culture of yellow perch. Limited knowledge of nutritional requirements has been an issue common in many culture species. A commercially available specialized diet has not been developed for yellow perch, and they are typically fed diets developed for rainbow trout (Hinshaw 2006). Furthermore, yellow perch become sexually mature before they reach market size. Small perch spend energy on development of reproductive organs and spawning rather than on meat production. Research to develop both sterile fish and all-female production has been conducted (Hart et al. 2006). The final, and possibly most concerning, issue is the limited supply of fingerlings for grow-out. To have a commercially viable industry, you must have a sustainable and steady supply of fingerlings. Consistent procedures for spawning yellow perch have yet to be developed. Additionally, formulated or artificial first feed diets for yellow perch fry have not been developed. In the midwestern United States, where the majority of yellow perch production occurs, pond productivity cycles are variable from year to year even with established pond fertilization techniques. As a result, in outdoor systems, timing of zooplankton blooms, which is critical for fry survival, can be substantially out of synch with the timing of first feeding necessities. Intensive indoor fry production would therefore seem to provide better control. However, indoor first feeding techniques are currently expensive and time consuming and achieve highly variable survival as well. Most commercial yellow perch facilities in the United States currently utilize outdoor production techniques for first feeding and either outdoor or outdoor/indoor combination methods for fingerling feed training.

I Look at aquaculture from more of a “Nutrient generator” rather than a specific fish and limited plant production type of operation. Whatever the fish generate in the way of waste products is the most important aspect to me. I Use their waste to feed plants in the greenhouses as well as field row crops. This is a cool fishing simulator in which you control a fish that must survive. The game is in cool 3D graphics so it will feel as if you really were in the underwater world. Just make sure your fish does not get eaten which you easily happen. Try to eat your way up in the food chain.

Spawning
Mature females begin to spawn in the spring when temperatures reach 6° to 12°C and continue for two to three weeks. In the wild or in culture ponds, females lay a strand of eggs, called ribbons, over a substrate, such as sand, gravel, or vegetation, and then several males will fertilize the eggs. Females deposit between 79 to 233 eggs/g of fish (Hart et al. 2006). In commercial culture settings, there are three methods of spawning yellow perch.
Fertilized yellow perch eggs (courtesy of Jim Held, University of Wisconsin).
- Pond spawning – Males and females are stocked in the ponds to spawn naturally, with adults being removed after eggs are detected, allowing the eggs to hatch and grow in the ponds.
- Egg collection – Fish are either spawned in tanks, or eggs are collected from the wild and brought to the hatchery to be incubated and reared.
- Strip spawning – Fish are continually checked for ripeness, ripe fish are then stripped (squeezed) of their gametes, the gametes are mixed together and then placed onto a suitable substrate for incubation (Hart et al. 2006).
Larval Cycle
Egg ribbons, whether collected from the wild, strip spawned, or spawned in ponds, hatch in 6 to 51 days depending greatly on the water temperature (Hart et al. 2006). Egg ribbons are delicate, and the percentage of hatch will depend on the quality of the eggs and the amount of handling. Newly hatched larvae will be 4.5 to 7 mm and begin feeding in a few days. They initially feed on small zooplankton such as Daphnia. Zooplankton remain an important part of the diet throughout the life cycle, but as the larvae grow, they begin to feed on larger invertebrates and fish, including other yellow perch (Hart et al. 2006). Fry and fingerling production methods strive to reduce cannibalism to the extent possible.
Fingerling Production
There are three methods typically used to grow larvae into fingerlings: pond culture, tank culture, and tandem pond/tank culture (Hart et al. 2006).

- Pond culture involves stocking larvae into ponds and allowing them to feed on natural sources of food maintained through pond fertilization. This method, while lower cost than tank production, results in high variability in the number of fingerlings and variations in growth that can lead to cannibalism.
- Tank culture, while more expensive due to cost of equipment and production of live feeds, is still being researched as a more desirable method for consistent production of yellow perch fingerlings.
- The tandem pond/tank method is currently the most common method used by producers (Hart et al. 2006). Newly hatched larvae are stocked into fertilized ponds where they feed on natural food sources. After one to two months, they are moved to tanks and put through a feed training process involving a transition from live to formulated feeds. The use of natural production in ponds cuts down on production costs, while finishing in the tanks provides more control over fingerling feed training (Hart et al. 2006).
Grow-Out

Fingerlings can be grown to market size in a variety of systems including ponds, cages, and recirculating aquaculture systems (RAS). Pond culture, stocking the fingerlings into a pond and feeding them a commercial diet until they reach market size, is the most popular culture method due to lower startup and production costs. Unfortunately, in regional temperate climates where yellow perch production occurs, water temperature variability results in seasonal production cycles for yellow perch (Hart et al. 2006). As a result, time of production from egg to a standard harvest size of one-third pound for food fish is about two years in outdoor ponds throughout the midwestern and north central regions of the United States. Yellow perch have shown to perform well in cages, but grow-out also appears to take two to perhaps three years. Recirculating aquaculture systems permit year-round culture of yellow perch and faster production cycles. However, RAS are expensive to construct and also require higher operational costs, redundant safeguard systems, and a fairly significant amount of training and/or learning time to efficiently operate.
Temperature and Water Quality Requirements
Yellow perch have a physiological optimal temperature range of 22° to 24°C (72° to 75°F; Hart et al. 2006), although yellow perch RAS producers have shown a tendency to maintain water temperatures between 18° to 20°C (64° to 86°F) to reduce potential for disease outbreak. Their upper lethal temperature limit is between 26° to 30°C (79° to 86°F). Additional water quality parameters are provided in Table 1.

Description
If you have ever had fish tank, then you probably enjoyed watching the gracious moves of these marine creatures. You probably thought that being a fish is easy and is better than being human. If such thoughts occurred in your mind, then you should see how things look like in the reality. With the new game with the early access you may follow fish in a new survival arcade Feed and Grow with gameplay. You will see how difficult life of a simple fish is, and how it changes with the growth of your pet.
You start the game as the smallest fish that you can only imagine. Your primary food will be crabs, starfish and even weed that you may consume before you get the second level. After you grow even a little, you may start eating fish, and the process of eating isn’t that simple as it seems. You should bite your victim many times, and then it starts looking like a ready dish, and you may open your mouth to gobble small portions. There are several modes of the game, and the most expected now is the multiplayer, because fighting with real enemies that act not like planned is much more interesting than playing against bots.

The easy mode is good only for those, who have no idea about how to play this arcade. After you learn how things are going on, you may switch to the hard mode, because here comes the fun. When you press the start button, you start to look around, and see where you can head to. After a couple of seconds something eats you, and voila, the game is over. You need to know that the sense of the arcade is movement, and if you stand still – get ready to die. At first you may consume only simple food that you don’t have to fight for, but if you notice that someone bites other fish, and you see luscious portions of food that you can’t afford at the moment, you should rush to that place, and eat as much as you can, because such nutrition will help you grow faster. When you grow to the highest available now level, there will be no need to hunt or bite anyone – you will eat fish with its bones, and you don’t need to wait for small portions. The game lasts to the moment, when you become the biggest fish in the ocean.
