M2 Questions- Elements of fish nutrition

According to the FAO, Fish In Fish Out is the number of tonnes of wild fish that takes to produce a tonne of farmed fish. The calculation is done according to the following formula:

The target FIFO for Sparus aurata is:

The components that fill in the blanks, in the correct order, are:

What is the option that contains the steps missing in the blank spaces?

Feeds are composed of water and dry matter and part of it corresponds to raw materials. Corn, straw, E, iron and yeast are sources of:

There are 12 steps in aquafeed production, fill in the blanck spaces with the correct step.

Fill in the blank spaces with the schematic food metabolism steps.

Fill in the spaces with the adequate stages of growth response to nutrient intake.

Fill in the blank spaces with the correct stages of energy flow in fish.

It is a fact that fish conversion [blank_start]efficiency[blank_end] is low in fish. There are [blank_start]three[blank_end] main reasons for that: fish are [blank_start]poikilothermic[blank_end] and require [blank_start]low[blank_end] energy for maintenance, water environment require [blank_start]less[blank_end] energy to live in, and, the use of [blank_start]fat[blank_end] in the feed that has [blank_start]more[blank_end] energy density compared to carbohydrates fed to land animals.

The fee conversion efficiency for salmon, sea bass and red sea bream are, respectively, 1.1, 1.3 and 2.

Proteins are required for the supply of [blank_start]essential amino acids[blank_end] and [blank_start]nitrogen[blank_end] for synthesis of non-essential amino acids.

Protein requirement varies between different species of fish. The protein content in feed for best growth of Chinook salmon, Gilthead bream and Red sea bream, respectively, are: 400, 400 and 500.

The roles of lipids in fish nutrition are energy supply, structure, precursors and signaling anomg others.

Lipids include fats, waxes, sterols, water-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, triglycerides, phospholipids, and others.

Triglycerides are important energy source and storages of fatty acids.

Phospholypids are elements present in the structure of membranes.

Fish can not synthesize fatty acids of the series w-3 and w-6 although they are not essential for many functions.

The essential fatty acids for freshwater fish are alpha linolenic (18: [blank_start]3w3[blank_end]) and alpha- linoleic (18: [blank_start]2w6[blank_end]).

The essential fatty acids for Marine fish are 20: 5w3 and 22: 6w6

The fatty acid requirement for coho salmon is [blank_start]1-2.5[blank_end]% of linolenic acid while for [blank_start]red sea bream[blank_end] is 0.5% EicosaPentaenoicAcid (EPA) and DocosaHexaenoicAcid (DHA).

What is the percentage of fish oil that can be replaced without affecting the fish growth?

Feed fatty acid composition reflects [blank_start]body[blank_end] composition because there is a tendency of [blank_start]conservation[blank_end] of [blank_start]Highly Unsaturated Fatty Acid[blank_end].

The optimum dietary lipid levels in diets for Sparus aurata and Pagrus pagrus are, respectively, 15% and 9%.

Which alternative on carbohydrate id correct?

If it is desired to increase the palatability of the feed, which element would be recommended to increase?

The metabolism of glucose in fish can be affected by carbohydrate soure, feeding rate and macro-nutrient balance.

Check the boxes of the alternatives that are correct or true about carbohydrates.

There are 4 fat-soluble and 11 water soluble vitamins in the fish body.

Which of the alternatives are correct?

Check the alternatives about vitamin D that are correct?

What is the name of the vitamin that exists in 8 forms, it's required for reproduction and has antioxidant action?

What is the correct alternative regarding Ascorbic Acid?

Fat soluble vitamins are absorbed together with [blank_start]fat[blank_end] and stored in [blank_start]tissues[blank_end] if their intake [blank_start]exceeds[blank_end] requirements, and therefore, are difficult to be quantified. Nonetheless, their presence in feed need to be moderated since [blank_start]hypervitaminosis[blank_end] may be toxic.

Minerals can be classified as basic elements, macro elements, and, microelements. Two correct examples of each category would be:

Which of these affirmations on minerals are correct?

Fill in the blank space with the correct information on mineral requirements of fish.

Fill in the blank spaces with the correct characteristics of feed composition.

Nutritional [blank_start]genomics[blank_end]: study on the influence of feed on [blank_start]genes[blank_end] and how [blank_start]genetic[blank_end] differences affect the [blank_start]behavior[blank_end] of fish response to [blank_start]nutrients[blank_end].

Fill in the blank spaces with the correct nutrition genomics steps.
