The measures and methods adopted to secure a disease free environment in all phases of aquaculture practices (i.e. hatcheries, nurseries, grow-out farms) for improved profitability.
Aquaculture continues to significantly expand its production, making it the
fastest-growing food production sector globally.
However, the sustainability of the sector is at stake due to the predicted effects of climate change that are not only a future but also a present reality.
In this Lecture, we review the potential effects of climate change on aquaculture production and its implications on the sector ’ s sustainability.
Various elements of a changing climate, such as rising temperatures, sea-level
rise, diseases and harmful algal blooms, changes in rainfall patterns, the uncertainty of external inputs supplies, changes in sea surface salinity, and
severe climatic events have been discussed. Furthermore, several adaptation options have been presented as well as some gaps in existing knowledge that
require further investigations.
Recirculating aquaculture systems (RAS) operate by filtering water from the fish (or shellfish) tanks so it can be reused within the tank. This dramatically reduces the amount of water and space required to intensively produce seafood products.
Here I have discussed Why AI is needed in Aquaculture and discussed various segments of Aquaculture in which AI is used and various AI tools used like in feed optimization,water quality management, diseases management etc.

اللحوم في المختبر..
فكرتها هي تصنيع منتجات اللحم من خلال تقنية تسمى (هندسة الأنسجة)
في المختبر.
وهو منتج حيواني ولكنه ليس من الحيوان.
وطرح أخر يقول: هو إنتاج لحوم حيوانات بدون حيوانات.
حيث تؤخذ الخلية البدائية الجذعية دون تأثير وألم على الحيوان غالباً من منطقة الرقبة وتوضع في بيئة لتبدأ في النمو والتكاثر بشكل مستقل عن الحيوان.
ستكون هذه العملية فعالة بما فيه الكفاية لتوفير الطلب العالمي المتزايد على اللحوم.
كل ذلك سيحدث دون أي تلاعب بالجينات ودون الحاجة إلى التدخل في التسلسل الجيني للخلايا.

3. Observe the nutritional
requirements of fish
Shrimp at different stages
of life require special needs
in food
The different requirements of
Shrimp are represented in high
quality feed that meets their
needs and ensures strong health
and good growth rates.

22. Feeding Behaviour
Detecting the feed:
• Shrimp’s vision is rudimentary
• Feed is detected by Chemosensory structure: Setea (antennae,
antennule, maxilipeds)
• Detection of soluble organic compounds (Proteins, AA,
HUFA,.....)
Eating:
• Probe the feed with pereopods
• Shrimp’s digestive system is primitive.
23. Shrimp Requirements
The requirements is:
Therefore, shrimp the following is required in feed:
- High content of digestible and absorbable protein
and increase metabolism.
- content of High Unsaturated fatty acids.
- Balance in amino acids according to the nutritional
requirements of shrimp.
- Feed size available to shrimp size in a crumbly and
granular.
- It does not dissolve in water and stable for a long
time, not less than two hours.
- It has an aroma or flavours that attracts shrimp.
- Feed additives to enhance immunity.
24. Attractive Flavours in feed
Attractive flavours in feed
Feed is detected by Chemosensory structure: Setea (antennae, antennule, maxilipeds)
25. Best Feed Size
The ideal granule size must be taken into your mind depends on the sizes of Shrimp
26. Rapid digestion and absorption rates mean rapid growth
The form of the feed and the method of its manufacture affect the rates of digestion and absorption
27. Rapid digestion and absorption rates mean rapid growth
The form of the feed and the method of its manufacture affect the rates of digestion and absorption
Digestive enzymes affect the better feed and digest and absorb it

35. Feed
• improved product stability (antioxidant/low pH)
• antimicrobial effect
• nutritive value of organic acids (energy)
36. Hepatopancreas
• reduction of pH
• efficient pathogen reduction
• activation of digestion
• antimicrobial effects
• stimulation of enzyme secretion
• better Ca and P digestion
38. Calculating the daily feeding
ration
• - Daily feeding ration is calculated according the biomass and the
average weight of the crop.
• - A theortical feeding table is used to calculated this amount of feed.
• - Feed amount is adjusted according to rearing parameters.
• - Shrimps are continuous intermittent feeders and hence should be
fed several times throughout the day.
• - Shrimps need about 3 -4 hours to digest, therefore, ideally,
feeding should be done every 3 - 4 hours.
• -Frequent feeding of smaller rations also provides better efficiency
in nutrient assimilation and reduces losses due to leaching.
• - During the first month: 2 feeding per day (dawn and dusk)
• After the first month: 4-8 feedings per day

42. Sampling to calculate growth and feeding rate:
• To calculate the quantities of feed required per day for any farmed
aquatic animal, there must be data on the average weight as well as
survival rates during a certain period of time, as the previous data can
be collected by taking samples from the animals farmed in ponds.
• - Sampling Must be done 1 hour before feeding or 2 hours after feeding.
• - Throw the castnet at 3 to 4 different places.
• - Period of the day with a high light intensity mus be avoided.
• - Sampling operator should always be the same each 10 days.
• - For shrimps below 5 gr, castnets is not efficient. Use feeder trays. Therefore shrimp have to be
taken from the feed trays 2-3 hours after feeding at a cool time.
• - Sampling must be done early in the morning.
• - Dry the shrimp and weigh them
43. What can I see in the sampile?
Heterogeneity of the crop (class of size)
Average weight (g)
% of soft, hard and molting shrimps
Dead shrimps?
Shrimp health status (necrosis, uropods, gut content, fouling)
Presence of Fish
44. Feeding vs Parameters
• Moulting
• Dissolved oxygen
• Temperature
• Any other stress factors (H2S, diseases,
Ammoniac,...........)
45. Feeding and Moulting
• Shrimp moulting is synchronized to
some extent with the spring tide
during the new moon
• Moulting cyle is separated in 4 phases:
PostMolt, Intermolt, Premolt, Molt.
• Shrimps can not feed during the late
Premolt, Molt and the Post molt.
Adjust the feeding ration according to
the % of shrimps moulting and soft
shell in ponds.
46. Effect of DO on feeding behaviour
• DO < 3,5 ppm is considered as stressful for shrimps
• At DO levels of 1,2 ppm shrimps show signs of hyper
activity (swimming near the surface, jumps).
• At DO levels of 0,9 ppm shrimps show signs of
lethargy (Mackay, 1974)..
• Shrimps avoid places where there is hypoxic condition
(DO< 2 ppm) and move toward better conditions (up
stream, close to the inlet for example)
