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.
Coastal fisheries are central to the lives of rural Solomon Island villages, supplying daily food and serving as one of the few sources of income. Yet, it is predicted that coastal fisheries in Solomon Islands, like many countries in the Pacific region, will not be able to provide enough fish to meet peoples’ needs by 2030. Proposed strategies to prevent this scenario include improving the management of coastal fisheries and diversifying sources of fish by enhancing access to other fishes, either through aquaculture or the use of fish aggregating devices (FAD).
This brief provides an overview of the monitoring and evaluation (M&E) system of the CGIAR Research Program on Aquatic Agricultural Systems (AAS) and describes how the M&E system is designed to support the program to achieve its goals. The AAS program aims to improve the lives of 22 million people dependent upon aquatic agricultural systems by 2024 through research in development.
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.
Early program achievements: In 2012 improved technologies enhanced productivity of Bangladesh fish ponds and generated: 2) $92m increase in combined annual income 3) $300 per household income from homestead ponds 3) $6000 more income per hectare from commercial fish ponds 4) $2000 more income per hectare from commercial shrimp ponds
Livelihoods in Solomon Islands are diverse, composed of a wide range of activities. The marketing of marine resources through value chains is an important component of this livelihood portfolio in many parts of the country. Gendered analysis of marine resource value chains can identify key entry points for equitable improvement of the livelihoods of those participating in these value chains. Case studies of two Solomon Islands communities (one each from Western and Isabel Provinces) provide insight into this issue.
