Fishing in seawater

When you want to raise seawater ginseng and fish, you must first understand After you have a certain understanding of the way to raise it, you must be fully prepared before you can buy the saltwater fish you want. Because the life of fish is relatively fragile, a little care may lead to illness or death, so Care must be taken when raising sea cucumbers and fish.

It is crucial to create a small biosphere suitable for the growth of marine fish: raise more sea anemones, sea urchins, seaweeds, starfish, corals, dried shrimps and other benthic animals and plants; 3 cubic meters of breeding space. Because marine fish are generally longer than freshwater fish, and the distance between fish in the ocean is large, you should try to use a large aquarium; buy sea salt to blend the sea water. The water is generally changed once a year, usually only 1/3 is enough. The key is the control of water quality and salinity. The salinity is probably between 1.020% and 1.023%.

At the same time, feed them with live bait. Experts believe that in addition to the specialized feed that can be purchased in the market, the use of live bait is a necessary condition to promote the healthy growth of marine fish: first, most fish like to eat shrimp eggs and shrimp seedlings; second, chopped squid , especially squid tentacles, are the favorite of larger marine fish; the third is to add nutrient solution on time; the fourth is to raise small sharks such as blacktip sharks, feed them at least once a day, and often feed one or two grass carp or crucian carp.

In addition, experts such as Hunter believe that several misunderstandings must be corrected: Straight crosses should be fed with Shanghai coastal seawater. Since all guinea fish come from the deep ocean with pure water quality and rich microorganisms, if you use local materials to raise fish in Shanghai offshore seawater, the lives of marine fish will be in danger; fierce sharks can kill people. However, even the smallest one is more than 1 meter long, requires a large space for exercise, and is not suitable for family raising; the water temperature must be specially heated. In fact, the water temperature can be consistent with the indoor temperature, and there is no need to specifically heat it.

The feed for seawater ginseng and catfish can be divided into plant-based feed and animal-based feed. The bait is mostly brine-based bait, which is live bait in the ocean or frozen ocean fish. Plant-based baits include seaweed, sea vegetables or green vegetables from the mainland. Animal bait includes small fish, shrimp, beef, beef heart, chicken heart, fry, frozen fish and shrimp meat or marine crustaceans, as well as blood worms, water fleas, water earthworms, etc.

Feeding seawater squid every day should follow the principle of small meals and adequate feeding. The amount of feeding is generally 1/3 of freshwater fish of the same size, and the number of feedings per day is 1-2 times. For carnivorous seawater fish, the feeding amount can refer to freshwater fish of the same size.1/3-1/2 of the category, limited to eating within 1-2 minutes. Omnivorous seawater fish can be fed water fleas, bloodworms, annual worms, fish scraps, etc. Vegetarian seawater fish mostly feed on seaweed, but they can also be fed chopped green vegetables, etc. The amount should be eaten within half a minute, and they should be fed 1-2 times a day.

The water quality requirements for aquaculture of seawater squid are relatively high. Generally, materials can be obtained easily, and water can be obtained from any area where seawater gallfish are raised. If you use artificial seawater salt for tap water or purified water, you must first raise water before raising fish. You need strong lighting, a protein separator, and various filter materials. It is best to use natural live rocks for the stones in the fish tank. The water raising time is 1 It takes about a month, sometimes longer, to benefit from the emergence of calcium algae. Various water quality indicators must also be tested. The best water temperature is controlled between 24 and 27 degrees.

We can’t take care of any kind of animal, especially fish, which are short-lived aquariums. We must pay special attention to all aspects in the early stage of raising seawater ginseng and fish, especially fish that do not have You can feed Taiko, otherwise it will easily lead to sacrifice.
