Harvesting Techniques HATCH Global Shrimp Information

Farmers in Ecuador and China do not conduct partial harvests for their crops before the ultimate crop harvest. In China, farmers declare that partial harvests require an excessive amount of administration and trigger disruption to production routines.

Shrimp Harvest Techniques You Must Learn

Hence, they prefer to harvest once per crop cycle. Ecuadorian and Indian farmers could also be pushed to have partial harvest by low shrimp densities and large pond sizes. In contrast, intensive and super intensive farmers in Indonesia, Thailand, and Vietnam have monetary incentives for partial harvests at the least two to three times prior to the ultimate harvest.

Shrimp Harvest Techniques You Must Learn

Harvesting strategies are extra depicted by pond design where farmers with low lying ponds small sufficient to use a net with use forged or seine nets to seize shrimp inside ponds. This is the case for farmers in India, Thailand, Vietnam and China where farmers primarily use seines to collect shrimp while Indonesian farmers with low mendacity ponds will use cast-nets to gather shrimp. If the farm has the capacity to gather shrimp exterior a sluice gate whereas the pond drains by gravity, farmers will use a sock-net to gather shrimp which is the case for some farms in Indonesia and all farms in Ecuador. In Ecuador, some will use a mechanical pump to harvest collected shrimp exterior a sluice gate and pump these directly into containers filled with ice
After harvesting, collected shrimp need to be sorted into measurement classes prepared for processing comfort. Farmers will even be paid in line with the full volume and value for each measurement category in their harvested crop. Most smaller farms will promote to collectors or sellers whereas bigger corporate farmers can promote directly to processors. In Indonesia, the sorting of shrimp is normally completed on farms by the ‘collectors’ team previous to being transported to processors whereas in India, Ecuador, Thailand, Vietnam and China, shrimp are solely sorted after arriving at the processors.

Innovation opportunities

There is immense opportunity for innovation in digital in-situ monitoring of shrimp biomass to predict harvest volumes and sizes in addition to enable for extra correct timing and of feeding and feed amounts. Improved monitoring will give processing companies advance information on what is obtainable, and it additionally provides farmers better negotiation power when discussing prices with buyers. As the market demand for different shrimp dimension lessons constantly fluctuates, figuring out the scale distribution of a particular crop permits farmers to set a harvest date that optimizes promoting worth. In-situ monitoring also negates the necessity for collectors to maneuver sampling gear from farm-to-farm, which potentially spreads contamination alongside the best way.

Faster strategies to harvest shrimp is extremely favourable to cut back stress during harvesting and keep away from compromising flesh quality. Farmers who use mechanical harvesting pumps can harvest typically up to 10 tonnes per hour. That is usually takes over four to 5 hours if executed manually using a larger crew nevertheless, with mechanical pumps, higher prices and better income should be acquired if sooner harvesting velocity is achieved.

For those who don’t have sluice gates, we expect that this technique to grow to be extra available across areas if farmers can rent giant water drainage pumps to drain ponds. Using large water draining pumps is common already in Thailand.
