Tropical Freshwater Fish Aquarium

I will say that as much as the expression “Canary in the coal mine” implies an early warning of danger in mines so does it in water too. In this case the fish directly helps us know the extent to which our ecological sphere is damaged, and helps humans to take the necessary precautions to save the environment.

Once the experiment was concluded, aged water was slowly added to the temperature- stressed fish in order to raise the temperature of its water. This helped to return its environment back to normal conditions.

More than 24 billion gallons of untreated sewage waste and storm water are pumped into the lakes annually. Pollution is increasing as well, due to the cottage development, where people enjoy spending their summers relaxing. For many years, the lake habitats have been affected by pollution and habitat destruction. The market for fish is tremendous; so much so, that we have depleted our fishing resources, and have had to market on invasive species.

Studies have repeatedly shown that as oxygen concentrations decrease, the abundance and diversity of fish decrease (Breitburg). Fish kills, in which large numbers of dead and dying fish float to the surface or wash onto shore, are probably the most dramatic and publicly visible manifestation of hypoxia and nutrient over-enrichment of coastal waters(Breitburg). In addition to mass mortalities that are easily observed, high mortality of fish lacking a swim bladder can occur leaving little or no visible evidence of fish at the surface or littering beaches (Breitburg). With no fish, shrimp, or crabs the Louisiana fishing market takes a huge hit that the economy feels in a major way. The gulf accounts for almost one-fifth of the countries fishing landings, which total to be three billion dollars (Petrolia). Fishing is not only a major part of Louisiana’s economy but also its culture. Without wildlife in our waters microorganism are given more opportunity to grow leading to bacteria infected waters. These bacteria infected waters could cause major health risks for those who come in contact with

But I think that I will be responsible enough. I took care of a Beta fish ( a Japanese fighting fish ) for 3 years without it dying. I changed it’s water in the bowl twice a week every week for

My friend had invited me along with him and his family to the ocean. It was vacation for the family, but for him and me it was the beginning of a week of serious business. We had an obsessive hobby to pursue. As avid and long-term freshwater fisherman, we were thrilled by the thought of catching those large and exotic saltwater fish we had seen on television a billion times before. Yet little did we expect there to be such vast differences between our freshwater fishing and the saltwater fishing, which we were about to pursue. We learned through trial and much error that in order to have a successful saltwater fishing experience we had to make adjustments to all the freshwater

Before attempting this lab, we conducted some research on what conditions catfish need to survive in an area. Catfish are better off at temperatures ranging from 88-90 degrees Fahrenheit. Their preferred dissolved oxygen levels are at least 4 ppm.(http://www.thefishsite.com/articles/1907/water-quality-monitoring-and-management-for-catfish-ponds/). The diet of catfish often changes as they age. Younger catfish primarily feed on aquatic insects such as dragonfly larvae, water beetles and fly larvae. By the time they're adults, catfish consume small fish, seeds, aquatic plants, algae, crawfish and snails.(http://animals.mom.me/catfish-eating-habits-9466.html). The alkalinity of the water needs to be at least 40 ppm but the catfish will be happier

Some fish are captive bred, but others are caught in the wild. Is it safe to catch wild caught fish? The answer is no. most of the time it is not because people catch the fish using a poison called cyanide. This chemical “quickly stuns the fish. it can be captured and later sold.” “A diver simply adds a pellet of cyanide to a bottle and squirts a bit on a target fish. Or someone may pump larger quantities down from a boat.” “For those who supply pet-shop fish,

For my entire life, my family has had a fish tank. Not just a small goldfish aquarium, either, but a huge, 90 gallon saltwater aquarium with everything from fish to coral to sea urchins, and more. One of my first memories was of pressing my tiny little toddler hands onto the glass, pointing out the “fishies and anemenenomies”, as I called them then. It was my dad's baby, his pride and joy. The effort that he put into creating the ideal environment was astounding and clearly visible- the aquarium was always vibrant and healthy. By the time I was seventeen, he had perfected his fish tank-keeping skills so much that the his corals, notoriously hard to grow, had overgrown the tank, and he needed to buy another.

When fish like salmon are farmed, often the fish are still kept in the ocean; however, they live inside of nets so that they are still contained. There are many ethical arguments based around these net systems because these nets pose threats to wild salmon. Captive salmon can escape from the nets, which allows them to breed with wild salmon. This can disrupt the natural gene pool of wild salmon. Farmed salmon have been shown to outgrow wild salmon when introduced into the wild, and typically have higher mortality rates, which would be poor traits to be introduced into the wild gene pool, (Hindar, et al., 2006). Unfortunately, with the invasive farmed salmon being introduced to wild populations from escapees of net systems, the recovery of the original wild salmon is unlikely, even if decades went by without more intrusive farmed salmon being present, (Hindar, et al., 2006). Another problem is that the nets do not contain wastes from the captive salmon inside, wastes such as uneaten feed, and feces from the fish are dispersed into the open waters of the ocean. Wild salmon can contract infections and parasites from captive farmed salmon in nets. A study indicated that these parasites, such as sea lice, and infections lead to high mortality rates in wild salmon passing near

According to the United Nations, 17% of fish stocks worldwide are currently overexploited; 52% are fully exploited; and 7% are depleted. This means that only an estimated 20% of worldwide fish stocks are not already at or above their capacity(Seafarms, 2013). Catches of Pacific herring have decreased by 71% since the 1960s, with Atlantic herring catches falling by 63%. Atlantic Cod catches have fallen by 69% in the same time(Seafarms, 2013). These are just a few of many facts and statistics on the topic of overfishing. The effects of these statistics and facts impact people’s and animal's lives around the

In actuality, fish are more work and require so much more time than the average cat or dog. That being said, there are plenty of “beginner” freshwater species that are relatively low-maintenance and hardy and are great to start out with, and by the same token, extremely complex and delicate fish best reserved for experts. Saltwater fish are also best kept for the experienced, who understand the needs of the fish they are keeping. Overall, anyone, beginner or pro, needs to understand amount of time, effort, and money that has to go into this hobby in order to be successful.

The water that combined with the drugs will make the fish get sick. The fish in the wild can reach the maximal size for the growth, but in the tank, the fish will get difficult to grow maximally. They may grow slowly because the place will be different with the river. You can only see the maximum size clown loach fish only 20 cm in length. The fish with the right care will life for the long time until 20 years. You can see the fish growth while you see your growth.

The fish tanks at Petsmart were all lined up against the walls, illuminated by blue and violet lights. Each fish tank held fish of all kinds of different shapes, colors, and sizes. My family had bought 5 glimmering fish, a bag of fish care supplies, and when we got home, my mom and dad took the old fish tank we had in our garage, and much to my delight, set it up in my room, on top of a low bookcase.

2. Explain why you considered these factors and how you dealt with them in order to create a sustainable ecosystem? What biological systems were taken into consideration?
