Java, blue and nile tilapia are the best species for backyard fish farming. Catfish. Exceptional taste and hardy resistance to disease and parasites make catfish another good choice for beginning fish farmers.

How can seafood be more sustainable? Explore how both wild-caught fisheries and fish farms can improve their environmental footprint. Buying local and sustainably-caught seafood is a great way to shrink your carbon footprint and support the local community. Ready to start sourcing sustainable seafood?
The farms can be built in a variety of locations to avoid sensitive habitats. They can also minimize or avoid the discharge of pollutants beyond the farms. The potential for disease and parasite transfer to the natural environment is low, and escapes of farmed fish can be prevented.
They, of all animals, appear to have the most minimal ecological impact, as well as minimizing welfare concerns that come about as the result of captivity. Photograph: Alamy Bivalves – a group that includes oysters, mussels and clams – are the best option for farming.

Bivalves are the best option for farming if one chooses to farm and/or eat animals at all. They appear to have minimal ecological impact while minimizing concerns around welfare in captivity. In fact, bivalves may not just be the best option in the ocean, but the best choice if one chooses to eat animals, period.
Where fish are farmed in their native waters, the concern is often genetic — if escapees breed with their wild counterparts, the genetic makeup of their offspring may be less suited to surviving and thriving in the wild.
Farmed fish are an excellent choice where the species wild counterpart is over-fished, often offering a more sustainable option. Fish and shellfish species which are commonly farmed include: Salmon, Trout, Sea Bass, Turbot, Halibut, Sea Bream, Kingfish, Barramundi, Grouper, Prawns and Carp.
The other important advantages of fish farming are that the production is carried out within easy reach of consumers and also the harvesting can be adjusted to demand, thus minimising distribution problems and spoilage.
This demand continues to grow each year. To meet this demand, people are harvesting more seafood — often in ways that deplete natural populations, damage sensitive habitats and pollute our ocean waters.
Aquaculture has the potential to supply the majority of the world's seafood and reduce fishing pressure on wild populations. But often, wild fish are used as feed for farmed animals. Alternative feeds that use insects and algae — instead of fishmeal — are providing fish farmers with more sustainable options.
The way some seafood products are caught or farmed can affect ocean health. Some methods are much more destructive than others, damaging habitats, depleting populations of discarded species, increasing pollution or affecting populations of other, unfished animals. Challenges facing the seafood industry. 1.
One way to improve seafood traceability is through certification programs, such as the Marine Stewardship Council and the Aquaculture Stewardship Council. Some seafood products are labeled to show that they are certified. Unfortunately, these products only represent a small percentage of the retail seafood market.
Challenges facing the seafood industry. 1. Overfishing. One of the biggest threats to our ocean is overfishing — catching too many fish, too fast for the population to recover. As a result, some fish stocks crash. Ninety percent of fish populations are currently fished at, or beyond, their sustainable limits.
Ninety percent of fish populations are currently fished at, or beyond, their sustainable limits. Fishermen feel the brunt of overfishing too. When populations collapse, fishermen can lose out on critical income. Strong management regulates catch so that fisheries remain healthy and thriving.
Ninety percent of fish populations are currently fished at, or beyond, their sustainable limits. Farming seafood — known as aquaculture — can help reduce the pressure on wild fish stocks. In fact, more than 50 percent of the seafood we eat today is farmed.
Seafood basics. Fishing & farming methods . When you choose sustainable seafood, you support the fishermen and farmers who are leading the way. The environmental impact of different fishing and farming methods vary — choosing less damaging methods supports a healthy ocean. Fishing methods.
Raceways are long, linear containment structures used for farming fish. They’re often in a terraced configuration and usually above ground. These systems can be indoors or outdoors. Types include flowthrough where the wastewater leaves the facility and recirculating where the water is treated and re-used.
Bottom culture involves growing shellfish such as clams, mussels and oysters on the seabed. Types include enclosed bottom culture where the shellfish are inside or under a net or other containment structure. When shellfish are cultivated using open bottom culture, they’re not confined or covered in any way.
Nearly one-third of the global marine fish catch each year goes to feed other animals, in part because those wild fish can be purchased inexpensively from developing countries , such as Peru.
It’s time to look to bivalves, the most environmentally sound animal species to farm. Bivalves – a group that includes oysters, mussels and clams – are the best option for farming. They, of all animals, appear to have the most minimal ecological impact, as well as minimizing welfare concerns that come about as the result of captivity.

Aquaculture must reduce its pressure on wild-caught fish for feed. One way to do this is to farm animals lower on the food web that require little to no feed, such as freshwater carps, tilapia, and bivalves. But this recommendation to increase production of herbivorous fish ignores animal welfare as a growing concern.
Aquaculture – the farming of aquatic animals – is one of the fastest growing food production industries in the world. But it’s growing the wrong way. Similar to factory farming, aquaculture is becoming an industrialized food system that is unsustainable and unnecessarily cruel. It doesn’t have to be this way.
In fact, bivalves may not just be the best option in the ocean, but the best choice if one chooses to eat animals, period. Without taking into account food that is wasted, scientists predict we will need 70-100% more foodto feed an estimated 9 billion people by 2050.
That said, in some sort of evolutionary fluke, mollusks, the large taxonomic invertebrate group that includes octopus, also includes bivalves. This group of animals, protected by a hinged shell and largely sedentary, seems to be considerably less complex.
Fish provides high quality protein in a hungry world. Fishermen in coastal areas around the world help feed their families and communities. Fish farms today could not supply the fish needed to replace wild-caught fish globally.
That’s a daunting thought in a world of 7 billion people. One answer to overfishing is fish farms or aquaculture. Indeed, according to Seafood Watch, over 50% of fish consumed today is farmed and that number is expected to rise. But even fish farms have their challenges.
But according to the Monterey Bay Aquarium – which houses the nonprofit research organization Seafood Watch – “Ninety percent of the world’s fisheries are now fully exploited, over-exploited or have collapsed.”. This means that we are removing fish at a rate that exceeds their capacity to replenish themselves in the wild.
The spread of the Asian carp – a species that wasn’t even raised for food but escaped when a fish farm flooded – is a case in point. Pollution.
Florida is a state with a long coastline and an understandable passion for seafood. We enjoy a huge variety of fish as consumers, while commercial fishing provides a livelihood for many people.
In the absence of coordinated management, fish species can be overfished to the point of extinction. For example, in the 1992 the cod fishery off the Grand Banks collapsed. Two decades later, it has still not recovered. Damage to the ocean floor with fishing gear like trawls or dredges.
