The CGIAR Research Program on Aquatic Agricultural Systems (CRP AAS) was approved by the CGIAR Fund Council in July, 2011. Solomon Islands, one of five countries targeted by the program, began its rollout with a five month planning phase between August and December of 2011. Subsequent steps of the Program rollout include scoping, diagnosis and design. This report is the first to be produced during the scoping phase in Solomon Islands; it addresses the national setting and provides basic information on the context within which the AAS Program will operate.
Tropical sea cucumber mariculture has potential to become a profitable industry and contribute towards natural population replenishment. Here, we synthesise the fields of progress, current impediments and research opportunities in tropical sea cucumber aquaculture arising from recent studies and an Indo-Pacific symposium. We present novel comparisons of data from hatcheries, earthen ponds and sea pens from published and unpublished studies in various countries. Of the few tropical species to have been cultured, only the sandfish Holothuria scabra has been bred extensively.
Effective partnership is central to the CGIAR Research Program on Aquatic Agriculture Systems (AAS). We recognize that many organizations are working to improve the lives of people living in aquatic agricultural systems, and together they spend hundreds of millions of dollars there each year.
This paper assesses factors influencing adoption of new shrimp aquaculture technologies within aquatic-agricultural farming systems in southwestern Bangladesh. The impacts of three new technologies were assessed: two Modified Traditional Technologies (MTT 1 and MTT 2) and a Closed System Technology (CST). A total of 789 farmers from 10 sub-districts in Khulna Division were surveyed randomly, including a control group of 350 farmers using traditional technologies.
Two sustainable, low-cost pond polyculture technologies have been developed to culture carps and mola in ponds, and culture carps and mola in ponds connected to rice fields. These technologies can increase total fish production from ponds. Farmers depend on carps as an income source, and mola is rich in micronutrients that can help to meet the nutritional requirements of the rural poor, particularly women and young children.
Throughout Bangladesh, there are more than 4.2 million household ponds. Regardless of their size and seasonality, whether they are isolated or connected to rice fields, each of these ponds has the potential to enhance its production with the addition of carps and mola. Mola is a micronutrient-rich small fish that is very popular, and grows well along with carps in ponds and rice fields. Carps are one of the most commonly farmed fish by small-scale farmers in Bangladesh. Carps grow to a large size and are profitable when sold at the market.
The effects of ditch size on growth and production of mono-sex tilapia, Oreochromis niloticus in rain fed concurrent rice–fish system were technically and economically evaluated for a period of 4 months. Three different ditch sizes were tried: 5%, 10% and 15% of the total cultivable rice field. It is concluded that rice–fish farming in a rain fed ecosystem of Bangladesh with medium ditch size and stocking density of 5000 ha-1 mono-sex tilapia can achieve better economic return.
Increasing the quantity and frequency of small fish consumption can boost nutrition, health and well-being of the people of Bangladesh. Small fish are rich in micronutrients, particularly vitamin A, iron, zinc and calcium, as well as animal protein and essential fats. Small fish are highly nutritious as they are usually consumed whole. Pregnant and lactating women and young children from the age of 6 months to two years should consume small fish as they promote healthy growth and development in children and can lead to better performance at school, and at work later in life.
The purpose of this information sheet is to provide basic details on how to grow or farm milkfish. Other information sheets will provide more details on pond construction, maintenance and feeding the fish you farm.
Conflict over environmental resources endangers rural people’s livelihoods and can increase the risk of broader social conflict. Yet action to sustain shared resources can also be a potent source of community building. Investing in capacities for conflict management can help launch innovations that build resilient rural livelihoods and strengthen institutions for equitable environmental governance. Governments and development agencies should invest in such capacity and integrate collaborative dialogue about environmental resources into program and policy implementation.
