Probiotic can act as Anti Pathogenous Bacterial Agent....

1. Function of Probiotic...

Knowledge of probiotic has been increased, recently we know that probiotic can act as anti- pathogens bacterial agent. The following way they work....
- Modifying intestinal microbiota ( Microbiota: itself microorganism, make barrier for pathogenic bacteria)
-Secreting antibacterial substances like: Bacteriocine ( proteins), Enzymes ( Proteases) and organic acid.
- Fight for space and food necessary for pathogens bacteria
- Modulating immune system of fish

2. Gut probiotic...

 Including above 4 functions Gut probiotic has another function like
-  Improve/increase intestinal villous/projection which absorb nutrients transfer to blood cell and formation of tissue
- Normalize the intestinal pH (in high pH  different pathogenous bacteria
 E. coli, Salmonellae) formed .

 3. Function of Red yeast...

Yeast ( saccharomyces ) is fungi. Red yeast has several function
-  Pigmentation ( coloring) of fish muscles cell
- Strong defense system
- improve liver function 

4. Function of Antioxidant:  
Antioxidants are compounds that inhibit oxidation. Oxidation is a chemical reaction that can produce free radicals, that may damage the cells of organisms. Antioxidants like- Ascorbic acid and Malic acid stop free radicals production.

Prepare certain parts per million (ppm) concentrations in water for disease treatment in fish pond culture.

Suppose an Aqua consultant told you to prepare 2 ppm Potash solution for disease treatment in your culture pond. On that time what amount potash ( gm) you will use to prepare 2 ppm solution in your culture pond.

Firstly,

Calculate your pond area (Length and width) and water depth, multiply it by 2 ( so that potash is 2 ppm) . Find out result definitely will gm.

Hydrogen Sulfide (H2S) gas source, management and harmful effect of Hydrogen Sulfide (H2S) on Fish pond

Up to one third of the content of feed used in culture system may be indigestible. And 25% of the feed become wasted if sinking feed is used. That’s why massive gas problem specially Hydrogen Sulfide (H2S) gas occur at the middle of the culture stage. If we do not solve it fish suffer huge suffocation problem and mortality occur. We can easily understand by following diagram.

Aeration with pond capacity, Importance of Aeration and Total oxygen budget in pond

Aeration:

Aeration is the process of adding oxygen to water and maintaining healthy levels of dissolved oxygen (DO) which is the most important parameters of water quality. Because aerobic type of respiration of living organisms only possible by DO.

Aerator

This process will help you to create a perfect production of fish, caring of fish and 

finnaly a good output from you feed. 

Ammonia source, Ammonia management and harmful effect of ammonia on Fish pond

Ammonia 

Ammonia in water basically stayed in two form unionized Ammonia (NH₃) and Ammonium ion (NH₄ ). Unionized ammonia is very much lethal and predominated when P^H is high. In pond environment P^H  up and down due to photosynthesis and respiration by pond organisms. Waste nutrients concentration from feed and feases promote dense phutoplankton. During day time in the presence of sunlight phytoplankton produce their own food by photosynthesis process. Day time CO2 is being low and due to rapid photosynthesis , removal of Carbon dioxide ( CO₂) converted to carbonate ( CO₃) and bi carbonate (H₂CO₃) and pH become high but at night time when CO2 is high it converted to carbonic acid ( H₂CO₃) and  pH become low. So there is a relation between pH and plankton.

When ammonia rise in pond, fish can not extract energy from feed effectively. Ultimately fish going to comma and result in death.

Different fish species in Bangladesh - Marine Fish Species of Bay of Bangol

Different fish species in Bangladesh - Part 3

 Naturally Bangladesh belong to Bay of Bengal which is rich in biological resources. If anybody see the map of Bangladesh they can easily understand why Bangladesh are paramount for capture and culture fisheries. We have billion of ponds, haor, baor,Bill, cannel , river. So we have huge opportunity for fish culture. Here I tried to include some renound fish which are available in Bay of Bengal.
   

Scientific name:Cynoglosus cynoglosus.

NUMBER OF GEAR/ FISHING EQUIPMENT USED IN BANGLADESH

NUMBER OF GEAR/ FISHING EQUIPMENT USED IN BANGLADESH (Part-1 ) :

There are different types of gear/fishing materials used in Bangladesh. Out of them some are Net and some are traps. Only nine net and six traps are used but net/jal are most preferable fishing device.

Different Banned products which are used in fish and shrim farm and Hatcheryp aquaculture

Different Banned products which are being used in fish and shrimp aquaculture :

An attempt was made to identify the source of hazardous antibiotics, nitrofuran and chloramphenicol. Several focus group discussions were conducted in Cox’s Bazar with different stakeholders of the value chin as participants. Although it was difficult to identify the exact source of contamination of nitrofuran in shrimp, three most suspected source could be hatchery developed PL, Indian PL found in black market and 8-12 types of feeds available for shrimp husbandry (4-5 are of Indian origin).

Different company product used for shirmp culture and hatchery management

Different company product used for shirmp culture and hatchery management :

In the present study of chemicals and antibiotics used in coastal aquaculture in Cox’s Bazar region have been investigated. The name of such compounds with the purpose of use, application methods and dose is listed in Table1. Many of such compounds are also common in freshwater aquaculture.

Different company product for fish, fish product analysis and overview of different aquaculture product uses

Different company product for fish, fish product analysis and overview of different aquaculture product uses :

A number of traditional as well as commercial products were used during pond preparation and for improving water quality of fish pond. The list of such branded products are used to reduce Toxic gases (like ammonia) and harmful pathogens trapped in the pores of such compound. They also absorb noxious toxic substance and off odor of water, and these ensure clear and healthy pond environment.
