23/04/2018: How inadequate cold storage systems constrain East Africa’s seafood market

by Shem Oirere, Journalist, East Africa

East Africa’s fisheries sector continues to grapple with the persistent challenge of inadequate, or a lack of cold storage facilities coupled with a troubled refrigerated transport industry whose woes resonate across the region’s food supply chain.


These inadequacies have contributed to the high post-harvest fish losses (PHFLs) whether in terms of physical damage, decline in quality or constrained market performance in a region that is also characterised by poor access roads, unstable electricity supply, inadequate landing sites and a weak policy enforcement culture.
 


The United Nations agency, ‘Food and Agriculture Organization’ (FAO) estimates that Kenya, Tanzania and Uganda incur PHFLs of between seven percent and 40 percent of their sardine fish and between five percent and 28 percent of fresh tilapia fish production in a year because of long and unreliable transport, lack or inadequate fish preservation facilities, use of crude equipment such as spears and hooks and also market forces that could be responding to situations such as oversupply of the fish.

The PHFLs could be much higher were researchers to overcome constraints in data collection, which the FAO says is “rather a challenge due to complexes in the industry” such as the many fish species in the tropics, varying fishing methods and equipment, many landing sites and deployment of different preservation and storage systems.

A previous sample survey by FAO among selected sub Saharan African countries estimated physical losses by sardine fish operators in Kenya at 7.5 percent while loss of quality of the same fish shot up to 18.7 percent or an equivalent of 3,600 tonnes every year. The survey indicated the country losses up to 28 percent of the quality of its fresh tilapia harvest annually.

For Tanzania, FAO found out the country’s fish operators suffer physical loss of up to 40 percent of their sardine fish harvest or an equivalent of up to 28,000 tonnes annually. Their losses in quality of the sardine catch goes up to 20 percent or an equivalent of 14000 tonnes every year.

A similar situation was observed in Uganda where physical losses in sardine fish goes up to 40 percent or 11,000 tonnes per a year and up to a five percent loss in quality of the same type of fish.

It would appear there is little public and private investment directed into solving the challenges that contribute to high PHFLs in East Africa despite the potential of aquaculture to turn around for the better the earnings of fish operators in the region and boost contribution of the sector to the respective countries’ gross domestic product (GDP).

20/04/2018: Feeding systems for frys and fingerlings

by Fish Farm Feeder, Spain

Fish Farm Feeder (FFF), is a Spanish Company that specialises in manufacturing Aquaculture Feeding Systems, and supplying automatic feeders to the global market.

With headquarters based in the main aquaculture production region of Spain and an established international distributor network, FFF knows first-hand the threats and challenges aquaculture farmers face today, mainly related to feed externalities.
 

Hatchery Central Feeder
FFF developed the first central feeder for hatcheries, a solution which aims to respond to the aquaculture sector’s needs by improving hatcheries’ success, through implementing automatic feeders with micro diets between 150- 500 μm of grain size. Hatchery feeders manage, monitor and control the feeding process based on different parameters (dissolved oxygen, temperature, etc.) and operate with high precision instead of the current artisanal and manual feeding process used for fingerlings. The hatchery feeder is supported by fully programmable software with learning ability from species-specific feeding regimens generating a continuous improvement of feeding protocols.

The system is provided with the ability to make decisions based on both the interpretation of insitu rearing parameters and accumulated experience. The hatchery feeder helps reduce direct feed costs, while diversifying the farmed species due to their low profitability associated with their early feeding stages. Objectives Hatchery feeder covers the following

Objectives
1. To optimise fingerling stocks viability by reducing direct feed purchases;
2. To decrease a fish hatcheries’ production costs through automation reducing mortality and deformity rates;
3. To diversify fish farmed species due to precise parameter control and protocol optimisation for each individual species.

Operational workflow
FFF’s hatchery feeders ensure specific Pathogenic Free Standards (SPF) and have the capability to monitor and manage feeds between 150-500 μm of grain size as follows:

1. Feed storage. This is carried out in four silos/hoppers for different feed sizes (from 150 to 500 μm) and types;
2. Feed composition and frequency is calculated by the software based on the datalogged parameters (water temperature, dissolved oxygen and hopper capacity);
3. Feed dosage mixing and provision. Feed proper dosage based in software decision is prepared in the intermediate silo until matrix outlet assignation;
4. Matrix delivery positioning. This is the one of the most critical technical developments of Fish Farm Feeder’s technology. The system consists of a mobile distributor along a matrix of outlets, where each one corresponds to a specific rearing tank;
5. Blower transportation from the matrix through the 20 mm hose system fabricated in polyethylene to maintain pressures between two and four bar.
