Indonesia rice-fish farming

 

 

Rice-fish farming has a long history in Indonesia and is believed to go back to the mid-1800s. This technique has been found good for both the fish and the rice leading to increasing farm household income, and employment.

Fish produced from rice-fish are either fingerlings/juveniles to be used in grow-out systems or harvested as table-size fish.

The targeted production of juvenile fish is normally achieved after 40- 60 days when fish attain about 50-100 g are to be stocked in cages. In such case, the stocking rate is usually high whereas the stocking rates are much lower when marketable size fish is targeted. Field management also influences the stocking rates of fish in rice fields. When the table-size fish is targeted, the stocking rates in no-feeding system are usually low and may range of 1000- 1500 fingerlings/juveniles/ha while this rate increases when supplemental feeding is provided reaching about 1500- 3000 fingerlings/ha; supplemental feeds used are rice bran, chopped cassava, corn kernel and others.

With the widespread use of the high-yielding rice varieties (HYVs), several issues of concern have emerged. The maturation of the HYV rice varieties in shorter period (100 days or less) represents a significant challenge in regard to the size of fish produced in this integrated system. However, a table size of about 125-200 g is acceptable in Indonesia. In Indonesia, common carp (Cyprinus carpio) and silver barb (Barbodes gonionotus) are widely used in rice-fish farming. The choice of fish is based on the availability of seeds, as well as marketability and consumer acceptance of produced fish.

Preparation of dried seafood mix in South Korea – Video

Video credit: Hisham El Gazzar (Egypt)

Review: Abdel Rahman El Gamal (Founder of the video channel)

Dried shrimp and seaweed in South Korea

 

This video was filmed in the Busan area (South Korea)

The video shows the typical process of preparing the mixture of dried seafood that composes seaweed, shrimp and fish. It is obvious that the mixing process in the shown operation –although done manual- but goes fast enough giving the impression on a reasonable weighing accuracy in regard to the contribution of each component (seaweed, shrimp and fish) in the final mix. The use of dried seafood –with the same or different components- in making soup including snack soup is a traditional and popular food of high nutritional value in South Korea.

Cage culture of tilapia in Indonesia (02) Cage culture of tilapia in Indonesia (01)

 

 

The inserted pictures show a private tilapia cage farm in West Java. Tilapia which is not native to Indonesia has been introduced to Indonesia from Taiwan, Thailand, and Philippines and turned popular among fish farmers and consumers.

According to published statistics, in West Java province being one of the key tilapia producers, 63845 tons of tilapia have been produced from floating net cages in 2013 whereas the domestic consumption of tilapia in West Java averaged around 2 kg/capita/year during the period 2011-2013. Temperature in the site of cages ranges from 20-27 degrees Celsius with a height of about 700 meters above sea level.

The Balai Besar Pengembangan Budidaya Air Tawar (Main Center for Freshwater Aquaculture Development – MCFAD*), which is the Indonesian governmental research center, is supporting tilapia aquaculture through the development of new tilapia strains targeting higher productivity as well as better profitability to tilapia farmers.

*The old name of the center was BBPBAT before changing to MCFAD

Smoking of African catfishing in Malawi (02) Smoking of African catfishing in Malawi (01)

 

 

The inserted photos show the smoking process of African catfish (Clarias gariepinus) as carried out in Makawa in Mangochi district. Fish smoking is a common processing method especially for large size fish. However, smaller fish are also smoked because of its fairly distinctive taste.  In fact, a wide range of consumers like smoked/dried catfish more than fresh. The smoked fish in general are marketed locally and also in city markets. The prices of smoked catfish fish are slightly higher the fresh fish.

The smoking process begins with fish drying that lasts for about half a day and then fish are placed on a wired oven for an overnight; sometimes fish are just put on a wire ring and fire is set under this ring. Normally big fish are gutted before drying. Compared to other processing methods smoking requires fairly large amount of firewood.  One of the two photos shows the smoking of catfish chunks which is done to allow the heat to penetrate the fish flesh easily in the chunks of the very large catfish specimens. In general, fish smoking is dominated by women.

Chicken fish farming in Tanzania

 

The inserted picture shows an integrated farm located at Morogoro, Mkuranga  District (East coast of Tanzania) in where chicken and fish are integrated. All-male tilapia and African catfish are the species used in the present system. Based on farmer’s experience, 30 birds are sufficient for fertilizing a 300-m2 fish pond. The present pond is about 500-m2 (20×25 m). The chickens are housed in a simple structure established above the water surface of fish pond. The photo shows how water turns deep green due to the plankton which is stimulated by chicken droppings; plankton whether phyto or zoo serve as the main fish sources supplemented by other ingredients such as rice bran. Also, the uneaten chicken feeds are swept to the fish pond and eaten by fish. The growing season of fish takes about 6-8 months during which, fish grows to market size. Locally manufactured poultry feed is provided to chicken. The photo was taken during the sampling of pond fish.

Small fish and nutrition in Bangladesh

 

 

 

More than 30% of Bangladeshis suffer from undernutrition, consuming insufficient quantities of vitamin A, iron and zinc. To help improve nutrition security in rural Bangladesh, two USAID-funded projects, the Cereal Systems Initiative for South Asia Bangladesh (CSISA-BD) and the Aquaculture for Income and Nutrition (AIN) project, are providing training and inputs to help families cultivate micronutrient-rich small fish and vegetables. Since 2014, the projects have collectively provided training to 68,584 participants.

Tuna slaughtering (Libyan waters)

 

 

 

The video shows the slaughtering of bluefin tuna (Thynnus thunnus) before lifting it by tail and placing it on the ship’s deck where the processing takes place. The few minutes taken in cutting the head, tail and fins using electric hand saw with almost no waste which indicates that personals who carry out this operation must have enough experience to carry out such processing at this level of perfection. Gutting the tuna and cleaning is thoroughly done. Tuna slices seen in this particular video have been frozen before heading to Japan.

Culture of “Mola” in rice fields in Bangladesh

Photos’ credit: World Fish Center

Review: Abdel Rahman El Gamal (Founder of the website)

Mola in Bangladesh (02) Mola in Bangladesh (01)

 

 

 

Mola (Amblypharyngodon mola) is a small indigenous fish that do exist in household ponds and natural waters in Bangladesh. In addition to its content of animal protein, mola is rich in vitamin A (20 times higher than commonly cultured fish species).  Mola is also rich in calcium, iron, zinc, and phosphorus.

Including mola as part of the diet can help those suffering from malnutrition and micronutrient deficiencies, especially pregnant and lactating women and children younger than 2 years of age.  In fact, human nutritionists claimed that “mola” can play a major role in lowering the incidence of child blindness, night blindness and infant mortality in Bangladesh. When cooked as a whole and processed into a paste, and mixed with rice and vegetables, turns to a child-friendly one-pot meal (khichuri) which is high in micronutrients.

Mola feeds on natural food organisms stimulated by fertilization. Moreover, the species spawns naturally two to three times a year and hence there is no need for sophisticated hatchery facilities)
