Info about aquaculture. Spending time restless

Hello everyone: Today we will see about seepage issues in aquaculture.  First I want to tell one example  - Life is not same for all people, it varies depends on individual person situation, if any good thing is happened to one person, the same thing won't work for another person..  Wait... Why are you telling this...  Most farmers thought seepage is very good... 😳 because if any succeed people have seepage pond then they thought seepage pond is good. But it is not worked for all ponds.  Now you compare my example!  Seepage :       Site selection and pond construction is very important. Perfect soil with good water holding capacity is important for pond construction.  * The adjacent site must not be taller than your pond.  * Your dike must be perfect height enough to prevent entry of outside water.         When the pond is aged or the soil is loosed or your site is shallow or higher from the near water sources are the important factors leads to seepage.  It is like diffusion proce

Hello everyone:         Today we will see about interesting topic on aflatoxin.  1. How many of you noticed the aflatoxin range in your feed bag?       Some feed companies mentions the range of aflatoxin on feed if they have more plant based meal in that feed.  Now, there are many questions arising within your mind, right?, we will see in brief, why they mentioned and what is the need.  We are farmers, we don't know more details, just we bought feed and give feed to the organism. But you have to know about the aflatoxin.  Aflatoxin is a mycotoxin, in short it is a toxin which is produced from the fungus Aspergilus flavus and Aspergilus parasiticus.      Oprimum temperature: These are developed at high temperature especially more than 32 degree celcius and developed at high moisture or humidity conditions.      These are mostly formed and produce toxins in plant based ingredients . Cereals, nuts etc... Selection and storage of ingredients is important.  Nowadays, plant based pr

Hello everyone:         We all know the inland fish production is very high compared to coastal farming. But the market price, high FCR, improper selection of ingredients, use pellet feeds, poor knowledge will leads to slow growth and reduce profit. Best solution is here....        Most of the farmers using only mash feeds in their carp ponds. Very specific regions only have good market price for carps and tilapia.       The other important factor for slow growth is improper protein in the selected ingredient.       There are many nutritional factors deficient will suppress the growth of the animal. Researchers identified in one species, which is fed with low level of (Thiamine) - vitamin  and high percent of carbohydrates source which will leads to death of fishes.  Why it is died?        Because, thiamine plays an very important role in the carbohydrate metabolism. If presence of any mineral like copper then it will destroys the thiamine function. So, thiamine deficiency

Hello everyone:          Today we will see about the use of calcium chloride in aquaculture.  Is it safe to use calcium chloride in pond?         In my opinion, calcium chloride is not the first choice of application in pond. Anyway it is safe, it hardens the shells, the hydronium ions formed from the reaction of calcium chloride with water helps to maintains hardness and alkalinity.  Calcium chloride reacts with water and produces cao and HCl. Then HCl reacts with water and forms Hydronium ions. Heat is formed in this reaction.  What is the reaction?         Calcium chloride is present in the form of small stone like structures. The ions are  with ionic bonds. Mixing of calcium chloride with water is an exothermal reaction.               It is an reaction, when one substance reacts with other substances and producing heat energy. Calcium chloride mix with water and produces calcium oxide and hydrochloric acid. This hydrochloric acid reacts with water and produces hydronium ions.     

Hello everyone:           Today we will see about the one of best disinfectant used for aquaculture.              Here we all are knows about Bleaching, Potassium permanganate, Hydrogen peroxide . But the other important and powerful disinfectant called triple salt which not leave any residues in your pond environment.  Triple salt:            It has chemical composition of Potassium monopersulfate  or potassium peroxymonosulphate. It have other names like oxone etc..             It has a strong oxidizing agent. It can kills wide variety of algae, bacteria, virus, fungi and other protozoan in your pond.  # Various trials shows, it has good effect against Vibrio harveyi in shrimp farming. How it works...         It also oxidizing agent only. It also kills or invades microorganisms by creating oxidative stress and leads to formation of free radicles in an organism.       It also oxidizes various organic matter in effective manner. It oxidizes nitrite, hydrogen sulphide, chlorine residue
