Breeding Sea slug

  I think there are people who'd like to breed the cute and beautiful sea slug.In saltwater fish shop, sea slug are sold is supposed sometimes, food is not being sold basically. Food is not only to raise their own basically at present. So, breeding of sea slug is not easy.Therefore, I can not really recommend the shop to buy saltwater fish, the sea slug. In addition, the sea slug you buy, do not release to the nearby sea. By releasing the non-native species of sea slug, it may breaking the ecosystem. So,advantage in the case of the collecting can be collecting together for food. Even then, it is necessary to collect the food to come regularly to the sea.

　In fact,  the researchers have facilities and in many cases, the environment can be collecting along with the sea slug bait near the sea. It is said that even in the aquarium, breeding of sea slug is difficult. You whether you can supply bait your own, try to collect thoughtfully.

　First, what to eat sea slug.Sea slug is alive for some period of time even if there is no bait, died gradually become smaller.Sea slug not only eat certain bait depending on the species.Previously, about food, was introduced in TOPIC3.Compared with the Sea Hare the food seaweed, sea slug is carnivorous, it is difficult to obtain bait.Sea slug bait that has been artificially created will not eat.Only one,eat a live artificial bait,but the only bait that seems to be a lack of nutrients. Depending on the season,some species in time, there is no bait because the ocean temperature changes.There are some sea slug bait of sea anemone, sea anemone sometimes eat sea slug. To breeding sea slug, you need to give bait, knowledge of the organism.

   For example,Blue sea slug eating a sea sponge. However, do not eat only particular sea sponge.Most sea sponge look the same except for color. Sea sponge is not only about living several months in a water bath. So, you need to look carefully around you find a sea slug.There was a sea slug of 5-6 at the sea sponge in the ocean,it means high possibility of that sea sponge is bait.

　Of course, need water.There are only a beautiful water place most sea slug.In order to breed, you must have a clean natural seawater,periodically, you must be replaced. I

　As introduced before,sea slug is a hermaphrodite,and place them in a water bath for 2 or more of the same species, sea slug lay eggs.Sea slug, also lays one individual, species that do not hatch eggs is most.Although it is not the always lay eggs,it affects seasons,water temperature and so on conditions.Even hatched, necessary knowledge, equipment, and it 100μ size,so it is not easily observed.Creatures of the natural world, such as the sea slug, has created different human livestock and pets are easy-to-breeding creatures.



・Examples of breeding environments
The table below when the rearing environment (from autumn until early summer) were bred 300 days White sea slug.

Water bath ｓize	60x30x45cm
Filtration	Top filtration  (filtration material: coral sand)
Lighting	Fluorescent lamp 18Wx2Lamp
Water replacement intervals	About 10 liters a month 1-2 months.
Keep warm device	Once 1-2 months. (Collected from the sea sponge)
Feeding intervals	Setting of 20 degrees the heater.  (in winter)
Other	Deniball & Denifa use. Nitrate 10ppm ~ 20ppm. (Measured by TetraTest)

White sea slug

・High temperature-is not good. About 20 degrees to 18 degrees is good.

(There is also a place which is kept at about 24 degrees.)

・Sea slug is hidden lighting is strong.(There are exceptions, such as Centipede mino sea slug.)

・The smell of food is filled, in water bath, it is difficult to find food. I'll take a good close to bait for sea slug.

・Examples of comparatively can be breeding sea slug

Centipede　mino sea slug

・Centipede　mino sea slug harboring symbiotic algae that the body is known.The symbiotic algae get nutrients produced by photosynthesis,Centipede mino sea slug is alive.However, the food is hydroid, hydrozoan not eat, only shed light, what really good, it is questionable.

Meribe sea slug

・Meribe sea slug to predation by small crustaceans that big mouth.Meribeumiushi to predation by small crustaceans that big mouth.As a simple example, brine shrimp is considered.Because it may become undernourished and only brine shrimp, so it may give from time to time, such as amphipods and skeleton shrimp came out to wash the seaweed.

Aeolidiella chromosoma

・Aeolidiella chromosoma eat sea anemone.Flow sea anemone is well adapted to water bath environment,it grow easily in water bath.Flow sea anemone is called Kali hated among those who raised the coral.Let's ask the people who are breeding  coral shops selling and coral acquaintance.

Grape shell 

・Grape shell eat brown moss that grows naturally in the water bath.If Grape shell grow water bath moss grows to some extent,without feeding.In an environment where the larvae is unlikely to be filtered, also breed in a water bath.

Okada sea slug

・Okada sea slug eats the piral sand worm attached to the stones of the tide pool.piral sand worm　is easy to find  so it in tide pools, easy to obtain the bait if you go to sea.

Hira mill green shell

・Hira mill green shell eat mill of seaweed. Heimel is seaweed commonly seen in places shallow,you can be taken without entering the sea if the tide.

Leaf of a tree green shell

・Leaf of a tree green shell eat seaweed, such as Hosotsuyunoito.Even in an environment water bath, such as seaweed Hosotsuyunoito,if you even prepare condition,can be breeding  bred relatively easily.It increased 1 ~ 2cm between one month.

 Emuramino sea slug

・Althought Emuramino sea slug of original bait is hydroids,it can be long-term breeding Asari as bait.In this way, a rare sea slug to eat anything other than natural bait in the ocean, it is a special exception.

　Life of the sea slug is a few years long ones, short ones is said to be a few months. So,often think of those who freely alive'll be the best in nature. If you think the breeding of sea slug will perform responsibly.

The method of photo a small Sea slug

Mr.Jun Imamoto

  Would it have taken beautifully how a very small sea slug. I would like to introduce my favorite sea slug photo book,Mr.Jun Imamoto author's “A wonderful living thing Sea slug”and “Cute Sea slug”of way with photos of sea slug.

 “A wonderful living thing Sea slug”

“Cute Sea slug”

  First, Mr. Imamoto was taken using a compact digital camera on the market. However, does not quite work out, he went on trial and error.As a system of cameras,combination of macro lens adapter with a high magnification single-lens reflex camera seems to be common.With this combination, you will be able to shoot big, the small sea slug a few millimeters. However, on the contrary, a large sea slug flooded from the screen.Mr. Imamoto has wanted to shoot a large sea slug and a small sea slug met at sea.

　Mr. Imamoto have tried several cameras, that he has finally arrived,Digital camera with high-magnification zoom function and it was a way to combine the close-up lens.If you install a close-up lens such as a magnifying glass to 10x zoom digital camera, you can shoot a 5mm slug to fill the screen. Is it okay if you return the zoom sea slug of 10cm. In addition, by removing the detachable water close-up lens, you can capture the whole even sea slug of 70cm.

 However, the problem of this time, appeared dissatisfaction the flash of lighting condition.Exposing the flash from near the top of the camera, you might end up in the sea slug really strong shadows. Mr. Imamoto is well organized the photos he wants to express,he was thinking about how to apply soft light evenly across as possible.Then was completed is the "diffusion plate lunch box." I purchased the 100 yen shop,drilled a hole the tapper lunchbox,he attached to the front of the close-up lens.And hit the flash from behind the tapper, the light turns evenly across around the lens, In addition, he becomes milky soft light by tapper. I was able to own parts of 100 yen effect similar to that of a system that nearly ¥ 100,000 called Ring.

Mr.Jun Imamoto　Camera

  There is another indispensable to Mr. Imamoto. It is a bar to stabilize the camera in water are called "support bar". It is a L-shaped bent aluminum plate was purchased few 100 yen.Have a profound effect on a small sea slug shooting just installed it. That focus on the small screen sea slug is not stable in water bodies are easy feat. Mr. Imamoto is mounting with tried to think, "I wish there was another one arms" is so was beginning.Again, in order to take the sea slug is beautiful, I need to experiment a lot. It seems important to enjoy of oneself liking shooting.I have two books of Mr. Imamoto. A small sea slug been taken  beautiful and large . And some explanation of sea slug, a description of the actual size,so,it is very fun photo album. Everyone, might be more like sea slug If you look at this book actually.

TOPIC8

Actual size of a Sea slug

Thompsonawatsubu shell 


  Please try to imagine the size of the sea slug. Do you think you are about the size of one?I think the most people think about 5 ~ 10cm. In fact, most of the sea slug is there are only a few millimeters only. Exactly what it is the size of rice grains on. If you look at the photos I put on the fingertips, I should be self-explanatory.Really small, it is hard to find a sea slug.

Igaryugu sea slug

The photo on the right of Igaryugu sea slug is a baby.It is very cute! ButThe photo on the above of Thompsonawatsubu shell is this size is the respectable adult size.It is very very small!

  But, are also found in the sea slug is so giant.Is from the newspaper on 19 June 2012.

- Found in the Osaka Bay giant sea slug  with more than 40cm in length. Companions of sea slug called "Yamatomeribe",seen in the Pacific Ocean side of the Miura Peninsula from Kyushu, being caught in the Osaka Bay unusual. -

Yamatomeribe

  There was an article that.

  I tried to find out about Yamatoribe, as a sea slug length of more than 40cm~60cm is like one of the largest.The body is in the form of semi-transparent an agar,A giant predatory called "hood" to 1/3 of the body is occupied. It is a very big mouth. Comes with a pair of projections 8 on the back, there are spots of bright red on the surface of the protrusion.Yamatoribe body shook from side to side, it is a swim to broadens or reduces the hood. There is also a citrus fruits smells peculiar to the body. Some sites writing "The hand touched the Yamatoribe smells was Zanthoxylum." Also Yamatoribe feces smells was a citrus fruits.

  It is quite different from the image of small and cute sea slug, in fact, it is quite scary so I met such a huge mystery creatures in the sea.The fluttering of protrusions that are not part of Yamatomeribe is all mouth,It seems eat anything if this very large mouth. It is scary and the folds around the mouth look like a fang. However, the actual meal, seems to be a food is small shrimp. It is cute food. If you look at the world of strange creatures, such as deep-sea fish　is pounded my heart!

Swimming Yamatomeribe Movie

  Appearance to swim illuminated by the lighting is beautiful rather than frightening. The unknown organisms can not imagine, there is a mysterious beauty.

Choco Egg

 and 

ChocoQ

  Surprisingly how! Yamatomeribe is like has become a figure of Choco Egg and ChocoQ series "mysterious creatures". As far as you see this, just visible only to aliens.Come and I want to get.

  In this manner,the sea slug have various species and shapes.In addition the size of sea slug many many types! It is a versatile creature sea slug is. There are many unique species,so I don`t get tired of seeing. If I still more find out about sea slug, I can meet interesting sea slug!
