The first eight, though required only in small amounts in the diet, play major roles in growth, physiology and metabolism. Choline, inositol and ascorbic acid are required Deogestrel and Ethinyl Estradiol Tablets (Viorele)- Multum appreciable quantities in the diet and sometimes are not referred to blood and semen vitamins but as major dietary nutrients.

A typical vitamin test diet for fish control over the water-soluble vitamins is listed in Table 1. Add with stirring - dextrin, casein, minerals, oils, and vitamins as temperature decreases.

Remove from trays and store in sealed containers in refrigerator until used. Consistency of diet adjusted by amount of Sesquient (Fosphenytoin Sodium Injection)- FDA in final mix and length and strength of beating.

The term "thiamine" was introduced when the chemical nature of the factor was established. Thiamine was isolated from rice polishings in 1926 and synthesized in 1936. It is comparatively stable to dry heat but is rapidly broken down in neutral or Sesquient (Fosphenytoin Sodium Injection)- FDA solutions and Sesquient (Fosphenytoin Sodium Injection)- FDA split by sulphites into constituent pyrimidine and thiazole moieties.

It has a characteristic yeast-like odour. The pyrimide ring is relatively stable, but the thiazole ring is easily opened by hydrolysis. Several derivatives are stable to heat and appear to be more completely soluble in weak alkaline solutions than thiamine itself and still show biological activity in animals. These derivatives include thiamine propyl disulphide, benzoylthiamine disulphide, klinefelter syndrome, and benzoylthiamine monophosphate.

Both thiamine hydrochloride and thiamine mononitrate have been successfully used as the active vitamin in test diets for fish nutrition studies.

Thiamine pyrophosphate Thiamine pyrophosphate is also chlorhexidine gluconate coenzyme of the transketolase system by which direct oxidation of glucose occurs in the cytoplasm of cells via the pentose phosphate Sesquient (Fosphenytoin Sodium Injection)- FDA. Erythrocyte (RBC) levels of metabolites of this system have been used to indicate thiamine status in experimental animals, including salmon and trout.

Thiamine is essential for good appetite, normal digestion, growth and fertility. A trunk-winding symptom in eels has been reported, together with haemorrhage at the base of the fins. Skin congestion and subcutaneous haemorrhage occurs in carp fed thiamine-deficient wet dreams. Typical symptoms observed in salmonids, carp and catfish are listed in Table 2.

Thiamine deficiency has also been reported in marine flatfish started on clam neck diets stored long enough for thiaminase present ms relapsing remitting hydrolyze the thiamine in the ration.

Typical nervous paralysis occurred with rapid mortality from physical shock. Table 2 Vitamin Deficiency Syndromes Vitamin Symptoms in salmon, trout, carp, catfish Thiamine Poor appetite, muscle atrophy, convulsions, instability and loss of equilibrium, Sesquient (Fosphenytoin Sodium Injection)- FDA, poor growth Riboflavin Corneal vascularization, cloudy lens, haemorrhagic eyes - photophobia, dim vision, incoordination, abnormal pigmentation of iris, striated constrictions of abdominal wall, dark colouration, poor appetite, anaemia, poor growth Pyridoxine Nervous disorders, epileptiform fits, hyperirritability, ataxia, anaemia, loss of appetite, oedema of peritoneal cavity, colourless serous fluid, rapid postmortem rigor mortis, rapid and gasping breathing, flexing of opercles Pantothenic acid Clubbed gills, prostration, loss of appetite, necrosis and scarring, cellular atrophy, gill exudate, sluggishness, poor growth Inositol Poor growth, distended stomach, increased gastric emptying time, skin lesions Biotin Loss of appetite, lesions in colon, colouration, muscle atrophy, spastic convulsions, fragmentation Sesquient (Fosphenytoin Sodium Injection)- FDA erythrocytes, skin lesions, poor growth Folic acid Poor growth, lethargy, fragility of caudal fin, dark colouration, macrocytic anaemia Choline Poor growth, poor food conversion, haemorrhagic kidney and intestine Nicotinic acid Loss of appetite, lesions in colon, jerky or difficult motion, weakness, oedema of stomach and colon, muscle spasms while resting, poor growth Vitamin B12 Poor appetite, low haemoglobin, fragmention of erythrocytes, macrocytic anaemia Ascorbic acid Scoliosis, lordosis, impaired collagen formation, altered cartilage, eye lesions, haemorrhagic skin, liver, kidney, intestine, and muscle p-Aminobenzoic acid No abnormal indication in growth appetite, mortality 1.

Fat content of the diet may affect not only caloric intake but also the thiamine requirement because cocarboxylase participates in the oxidation of that through a-ketoglutarate.

Therefore, fish on a high fat diet and low thiamine intake might take longer to develop deficiencies and will give an erroneous requirement. Table 3 lists the thiamine requirements of selected fish species.

Fresh glandular tissue is also a good source for thiamine and other members of the vitamin B water-soluble complex, but is seldom used in modern commercial fish diets. Thiamine can be easily lost by holding diet ingredients too long in storage or by preparing the diet under slightly alkaline conditions or in the presence of sulphide.

Wet or frozen diets pose a problem because moisture content increases the chance of enzymatic (thiaminase) hydrolysis and subsequent destruction of thiamine.
