Shrimp waste

Description: 

Shrimp waste consist of head, shell and meat portions of shrimp that are being processing for human consumption. Approximately 70 % of the total shrimp landing becomes waste, so there is a tremendous tonnage of shrimp waste produced. A portion of the CP that is contained in shrimp meal is in the form of chitin, which is not readily digestible.

Waste that is associated with shrimp (prawns) that are being harvested and processed for human consumption.

Feeding Experiments: 

Weight gains and feed conversion was reduced when shrimp waste meal replaced fish meal in broiler diets, but feed intake was not found to be different (F)(CAB 19991411675)(Fanimo, 1998). When shrimp meal was compared to fish meal in growing chickens diets with the same dietary CP levels growth was decreased and when supplemented with lysine gains were increased (B)(CAB 731406929)(Jarquin, 1972). As the level of shrimp waste meal increased in the diets of broiler the mortality rate also increased (F)(CAB 19991411675) (Fanimo, 1998). Up to 66 % of fish meal could be replaced with shrimp waste meal in the diets of broilers without reducing performance (F)(CAB 19991411675)(Fanimo, 1998); (J)(CAB 971410693)(Fanimo, 1996). 

Feeding shrimp waste meal has been shown to affect the pigmentation in the tissues of broilers to be increased (A)(CAB 741422517)(Chawan, 1974). Protein quality of shrimp waste meal was found to be inferior to fish meal, but was improved when supplemented with methionine and lysine (E)(CAB 20001408357)(Fanimo, 2000). Performance was higher in oven dried vs sun dried shrimp waste meal (G)(CAB 19991411690) (Oduguwa, 1998). Feed conversion was found to be superior when shrimp waste meal was compared to fish meal, calm meal or silkworm meal, as was growth rate in a feeding trial with fish (Macrobrachium rosenbergii)(I)(CAB N244528)(Ravishankar, 1988). Shrimp meal Digestible CP was found to be 84.29 % when fed to fish (Macrobrachium rosenbergii)(I)(CAB N244528) (Ravishankar, 1988). Protein digestibility of shrimp waste meal was found to be 89.68 % when fed to fish (Clarias batrachus) (H)(CAB 991400028)(Borthakur, 1998). Diets containing shrimp meal and silkworm meal performed better as compared to when diets were based only on fish meal or silkworm meal (2)(AGRIS 87-110484)(Ravishankar, 1986).

Feeding and Handling Characteristics: 

Shrimp waste from the processing of black-tiger prawn consist of 38 % heads, 7 % shell and 55 % meat (1)(AGRIS 1998-100335)(Piangchai, 1994)

Nutrient Characteristics:

Ether extract (EE) level was found to increase in the waste as the age of the prawns being processed increased 1.5 % EE (1 month old) to 3.4 to 4.5 % (fully grown prawns) (1)(AGRIS 1998-100335)(Piangchai, 1994)
