A) Bisakah Ikan laut diternakkan?
Beternak ikan biasanya dilakukan di pantai. Bibit ikan itu diletakkan di dalam bak, kolam, atau tong besar agar mereka tumbuh dengan aman. Untuk itu, selalu diperlukan air laut. Para ahli di Eropa melakukan percobaan dengan ikan salmon yang diternakkan dalam kandang, seperti ayam betina. Ikan itu diberi inseminasi buatan. Telurnya juga ditetaskan dengan mesin penetas. Setelah menetas, ikan itu dipindahkan ke kolam pembiakan. Meskipun ikan itu dirawat dan diberi makan, ikan yang menetas sangat peka dan mudah sekali terkena penyakit. Mereka sangat sulit tumbuh di ruang sempit.
B) Apakah Bunga Laut adalah Seekor Binatang?
Bentuknya yang indah dan berwarna warni memang tampak seperti bunga. Sebenarnya, bunga laut adalah binatang. Dengan kakinya yang lebar, bunga laut melekat pada dasar laut atau batu karang. Sementara itu, tubuhnya bergerak-gerak dalam air. Orang harus waspada terhadap “bunga” yang sangat indah itu, karena pada setiap “lengannya” yang disebut tentakel terdapat duri beracun. Duri itu jumlahnya banyak sekali dan terus bergerak. Dengan duri itulah bunga laut menjebak ikan, kepiting, dan binatang lunak. Ikan itu akan merasa terbakar seperti jika kulit kalian menyentuh tumbuhan gatal. Lalu, ikan itu akan lumpuh. Bunga laut pun memakannya dengan lambat, namun rakus.

A) Can marine farmed fish?
Fish farming is usually done on the beach. Fingerlings were placedin the tub, pond, or a large barrel in order for them to grow safely. To that end, it is always necessary seawater. The experts in Europe to experiment with farmed salmon in cages, like a hen. The fish wasgiven artificial insemination. The eggs also hatched by incubator.After hatching, the fish were moved to the breeding pond. Although the fish were cared for and fed, the fish were hatched very sensitiveand easily affected by the disease. They are very difficult to grow in tight spaces.
B) Is An Animal Flower Sea is?
The form is beautiful and colorful it looks like a flower. Actually, seaflowers are animals. With her legs wide, sea flowers attached to the seafloor or coral reefs. Meanwhile, his body moving in water.People should be wary of "interest" is very beautiful, because ineach "arm" called tentacles are poisonous spines. Polynomial thornonce and keep moving. With sea flower spikes that trap fish, crabs and molluscs. Fish will feel burning like if you touch the plant itchyskin. Then, the fish will be paralyzed. Flower sea was eating slowly,but greedy.
