A limbless cold- blooded Vertebrate animal with gills and fins and living wholly in water. In internal resources of Bangladesh, 260 Species of native and 12 Species of foreign fishes are seen. In the same way , there are 475 species of fishes in seaborne treasure fish culture and fisheries got . Fish culture and fisheries got a momentum in this country after the introduction of induced breeding of carps with pituitary extract in 1967.Once the major carps were the target species,but now many exotic fishes are cultured in ponds an lakes. Of the total annual fish production about 307. Comes from the culture sector and the remaining 70% comes from the inland and marine capture sector. In internal resources the fishes that are commonly seen are Grass carp, Big head carp, Common carp, Tilapia, Catfish, Phai pangs Sorpunti, Mullets (Bata) Chilta, Bual ,Catla, Rui, Shot, Taki, Gojal, etc. Vhuri, Datina, Vetki. Pupechanda, (Pomfrets) Siton, Lakka are the fishes of oceanic treasuri in Bangladesh. 
In Bangladesh , there are 24 species of shrimp in internal fresh-water resources and 36 species of shrimp in oceanic resources. Among them Lobster, Brown shrimp, white shrimp, pink shrimp are main Lobster is culture in fresh water  and while shrimp and brown shrimp and culture in salt water.

Accommodation/ Resources :
The total Resources In Bangladesh can be classification 3 Ports. Fish , Shrimp and other aquatics live in these Resources . These Resources in Bangladesh regarding their geographical and natural condition, are parted in such way such as.
Inland closed Water Resources :
The total measurement of inland closed water resources in 2,92,378 hector including ponds, canals, coastal shrimp are a etc. Among them the are a of 1,42000 ponds is 1,46890 hector.

 Inland free resources :
The total quantity of inland free resources is 80,47,316 hector, marshy land/ swamp is 1,14161 hector and damped land is 28,32,772 hector.
oceanic Resources :
In the southern part of Bangladesh , the covering of oceanic Resource is 1,66,070,00  hector.
Benefits of Fisheries, collection and Marketing :
A remarkable part of the number of population is restated to it. Not , trotter , Boat , Many types of instrument employed in collection fish-are our asset.

Different Fish Farming System :

Java Barb ( Rajputi)

Java Barb ( Rajputi)

Farming System of Rajputi ( Java Barb) :
Java Barb is a rapid growth full foreign species. There are some characteristics of it regarding it's Farming system such as ,,,
* Its possible to form /cultivate  it in small and shallow seasonal ponds and canals or other resources.
* In paddy fedlds it can be farmed
* It grows rapidly and becomes appropriate to be sold within 4-5 month

Pond Selection :
One should select pond with mixed soil, the area of 10-25 per hundred. It's depth is must to be 1-1.5 meter.
Preparing pond :
It is very important to prepare the the particular pond properly to make a hopeful benefit from fisheries. Regarding all the aspects and pants lime water, soil ,etc.
Pond should be made ready:
It is important to salted young fishes with big size and obtaining proper quality. The fry should be of the size 6-8 c,m.  Many species need periodic sorting by size, so that larger  fish do not cannibalize smaller fish. With favorable water conditions, regular water change, and generous feeding, the fry should grow quickly. Cull unhealthy and deformed fish. 
Equipping/ Supping Supplementary food:
The habits of taking food of various species are different. food for Rajputi  (Java Barb) Is to be supplied at two times doily Rajputi Is fond of mustard-cake, rich-dust, insect larvae and small fry. Per day 2-3kg. Small fry is needed to be provided. 
Using lime and fertilizer after storing  :
By rising the alkalinity and hardness of water , liming serves as direct source of soluble calcium for pond food organics. To time one firstly have  to do is to make the selected pond dried .Nest, to determine weather a pond needs to be timed, check total alkalinity. Collect a water sample from the several inches below the surface, making sure the sample contains no bottom sediment .
Regarding the conditions of soil and water, 25-40 kg . cow-dung or 100-150kg cock-dust or, 35kg mustard-cake is needed. 
Cate hing fish and marketing :
If balanced food is provided and sufficient caring is ensured, Rajputi  ( Java Barb)  a obtain the weight of 150-200gm. In seasonal pond, catching fish will be finished within 6-7 month.

Goat farming

In ruminant animals goat and sheep are the first domestic animal. Goat are very useful animals. Meet and milk of goat are very nutritious and goat farming is very easy. Goat are small so it take small place and it suffer from disease less than other domestic animals. They are very productive cause female goat give birth minimum 4 child in a year. Generally black Bengal goat is very familiar in Bangladesh.
Benefits from goat, Goat farming got farming in bangladesh, breeding  Goat ,Jamunapari goat gives a large quantity of milk, nutritious,  protein in goat milk,

Benefits from goat :
Goat are become perfect for breeding within 6 or 7 month and goat give birth minimum  child in a year.
goat are small domestic animal so it takes small place. Small capital is needed for goat farming so everyone can do it.
goat can survive easily than others domestic animals.
goat need little amount of food than cow or buffalo.
it suffer from disease less than other domestic animals. 
milk of goat are very nutritious.  

Goat milk :
Black Bengal goat give a little quantity of milk but Jamunapari goat gives a large quantity of milk. Goat milk and its products of yoghurt, cheese and powder have three-fold significance in human nutrition. Feeding more starving and malnourished people in the developing world than from cow milk. treating people afflicted with cow.
Milk allergies and Castro-intestinal disorders, which is a significant segment in many populations of developed countries; and  filling the gastronomic needs of connoisseur consumers, which is a growing market share in many developed countries. It has been found that goat milk has a significantly higher dye-binding capacity per unit protein
(1% more than cow milk) and a lower infra-red
absorption (4% less than cow milk), making it necessary to use different calibration curves for each species to measure milk protein
content. This has been confirmed in studies, when testing with cow milk standards resulted in 0.04% less fat and 0.27% less protein in goat milk.
Goat Meet : 
Goat meet is known as mutton in our country. The nutrient value of meat, as also other food items, is becoming increasingly important in the health
management of people. Calcium is an important element in the body required for bone development, neuron-muscular activity, secretory
functions, buffers, certain co-enzymes and nutrients for the nursed young. A comparison of the vitamin content of mutton, liver and kidney indicates the richer source these organs are than muscle. These differences could be expected in goats also.
Goat skin :
Plain, natural shaped calfskin and goatskin hides are becoming more and more popular for accent pieces. In addition, many people buy calfskin to make into lampshades.
A single goat skin hide will measure approximately 2 x 3 feet in dimension, with a typical calf skin being about the same size. This is the perfect size for a small accent rug. In addition, both, goat skins and calf skins can be easily cut up to use in upholstering furniture.

Goat hair : 

Goat is the source of the wool that becomes cashmere fiber for clothing and other textile articles.

Other nursing 
Irrigation: in taros land will be given little irrigation. After plant a bit irrigation helps grow plant quickly. if   not rain or soil wet low then needs irrigation. Irrigation will be given by the canal in middle of two tardy. This canal are used both irrigation and extraction.soil give on trees tuber and give straw on land: Ride give high is a main nursing  of taro. Ridge can’t give in 1 time, it gives 2-3 times. If trees tuber covered properly then small plant can’t grown. Malching  is very important  for taro. Straw is to be given on land so that illegal plant can’t grow. It also helps to fertile the land.  
Insects and diseases: leaf scorch diseases is very harmful, it can control using cooper.

Crops life time:  Generally taro is 150-210 days crops.

Collect crops: in the rainy monsoon taros leaf will red and yellow. it is the time of collect taro. Generally it collects in November to December. If we want to use it as a seed we will collect it after tree die. After cleaned it can be stored and sell.        
 Production: production depends on climate, verities and nursing. It product 20-25 ton per hector.
