New Zealand edible saltwater fish species
I have written 9 times about deep sea fish until now. And this post is last.
I would like to introduce deep sea fish which may be exterminated recent years.
First, I introduce a fish called hoki.
Deep sea fish which inhabits the depth of water between 100m and 1000 m of the sea near New Zealand.
The length is between 70 and 120 cm.
Having a big eyeball, the body has a very long and slender form where it tapered off.
Hoki is predatory. It eats a fish and there is a sharp sharp tooth in a big mouth.
Although a lantern fish is used as the main game, the crustacea and a cuttlefish also eat.
It will lay eggs around June to July.
A life is about 10 to 14 years.
It is an edible fish which circulates not only in New Zealand but in the whole world, and is general white-fleshed fish.
McDonald's use Hoki for fhyleofish which is name of hamburger.
Every year is used also in 7 million km, and especially hoki has greeted the crisis of extinction.
Although McDonald's reduced the amount of the hoki used, if a fish catch frame increases, it is supposed that it may increase from now on.
In Hotto Motto, it is used as materials of the fly of the white-fleshed fish of paste lunch.
Although the New Zealand government also performed fish catch restrictions, but it is said that the number of hoki is continuing becoming fewer.
Next, what is introduced is deep sea fish orange roughy.
Some kinds named roughy generically in three oceans including orange roughy who produces widely are the objects for a fish catch in every corner of the earth as an important edible fish.
Generally the deep sea fish which live in the deep sea of low-wash temperature has a late cycle of growth and breeding.
Therefore, we are anxious about exhaustion of the resources by overhunting.
Orange Rafi's fish catch started in the sea near New Zealand in early the 1980s.
It decreased 70% of resources in only six years, and became extinction anxiety deep sea fish instntly.
Many deep sea fish is driven away to the crisis of extinction also at others.
According to research of the group of Canada, the number of deep sea fish is decreasing quickly under the influence of the deep sea trawl fishery which started in the 1970s.
It is insisted that immediate measures, such as a setup of a refuge, are required.
Deep sea fish also has many which will be useful in about 60 years and reach the length of 1 meter.
Growth and deep sea fish's sex maturation are late, and its ability of reproduction is also low.
Therefore, it was thought that it was difficult to recover if a number becomes fewer by a fish catch.
However, since there were many mysteries in deep sea fish, there was little scientific research.
A research consortium analyzes the data of the test operation carried out from 1978 to 94 in the northwestern Atlantic Ocean about five kinds of deep sea fish caught accidentally frequently.
It turned out that five sorts of deep sea fish are decreasing in number by no less than 87 to 98% in 17 years.
These are equivalent to the extinction anxieties whose danger of very near future extinction is very high.
If a fishery is continued as it is, it will be presumed that 99% or more of the number of habitations is lost.
Thus, many deep sea fish is exposed to the crisis of extinction by being accidentally caught in a net as edible.
Since deep sea fish has many which have fearful appearance, it is seldom sold at a market.
Therefore, it is sold to a restaurant etc. at a low price, and is eaten.
I think that extinction of deep sea fish can be stopped according to our device.
I thought that it was strong with the deep sea fish of a mystical existence not being annihilated.
I think that what is necessary is just to get many people to consider extinction of deep sea fish also alone through this blog.
Copper is also toxic to fish, especially2002-04-04 03:51:43 by MeM
Goldfish. There are several vital dyes that are relatively safe for FRESHWATER fish with ich (I know nothing about saltwater fishes) that are sold in pet stores: methylene blue is very safe for fishes but kills plants. There is a more commonly used drug now, malachite green, which is safe for plants and fairly safe for most fishes. But I believe a few kinds of FW fishes have trouble with it.
If I remember right, you don't have to change the water after using M.G., it naturally breaks down. But you will after M.B., first because it stains the water a deep blue, second because of your plants
