Development of Bighead Catfish (Clarias Macrocephalus) Culture for Sustainable Aquaculture in Cambodia

The goal of this project is to develop and apply new applied aquaculture research technologies, in order to support bighead catfish (BC) culture in Cambodia. The project will be articulated around two main investigations, namely (i) the development and scaling of cost-effective feeds for sustainable culture of BC in Cambodia; this will lead to the determination of the optimal protein and lipid requirements in grow-out stage, the formulation of soybean-meal-based commercial feeds for BC, and the development of feeding protocols for BC; (ii) the building of the infrastructural and human aquaculture research capacities of local institutions that will ultimately lead to the establishment of new research facilities, renovating of the existing facilities, training of local scientists and technicians on basic and applied aquaculture research approaches, running an aquaculture research station, and formulating and manufacturing aquafeeds.

Enhanced Coastal Fisheries in Bangladesh II

Enhanced Coastal Fisheries in Bangladesh II (ECOFISH II) is a 5-year project funded by the United States Agency for International Development (USAID). Jointly implemented by WorldFish and the Department of Fisheries (DOF), ECOFISH II is built upon the previous work of the original ECOFISH (2014–2019) project regarding hilsa shad production in the Meghna River ecosystem. ECOFISH II is reducing the impacts on the natural resources and fishing communities along the Teknaf–Cox’s Bazar peninsula from the influx of over a million Rohingya refugees. It is also reducing the impact of the Naf River fishing ban on host communities in Teknaf. ECOFISH II is scaling up lessons learned from the previous project while expanding interventions for improving the livelihoods of fishing communities and enhancing biodiversity conservation in the artisanal fisheries of the Bay of Bengal. The ongoing conservation activities in the lower Meghna sanctuaries and the improved management of the Nijhum Dwip Marine Protected Area (MPA) remain integral parts of the project.

Harnessing Machine Learning to Estimate Aquaculture Production and Value Chain Performance in Bangladesh

Digital technologies are undergoing a revolution. Artificial intelligence (machine learning), remote sensing, smartphones, mobile internet, social media, and open source data collection and video production software open up an array of new possibilities for cheaply collecting, analyzing and communicating information in new forms, to multiple audiences. Drawing together all these strands, this project will combine survey based research techniques with remote sensing, machine learning and video production, to generate knowledge products disseminated via digital media to reach and serve the diverse information needs of farmers, enterprises, researchers and government. The project is also intended to build organizational and individual capacity in Bangladesh for conducting rigorous research on socio-economic and spatial dimensions of aquaculture, and contribute to a more enabling environment for fostering sustainable aquaculture growth.

The project comprises three components:

  1. surveys
  2. remote sensing
  3. capacity building. 

Component 1 follows the "stacked survey method" developed by Michigan State University to survey a sample of 1,100 hatcheries, feed suppliers, farmers, and fish traders interviewed by Michigan State University researchers in 2013 in the Feed the Future Zone of Influence. Comparative analysis of 2020 and 2013 data enables identification of new and emerging technologies and practices. Additional in-depth interviews are used to gather detailed information on these practices and produce short videos featuring individuals talking and demonstrating their innovative behavior in their own words to provide easily relatable content to be disseminated widely through social media platforms.

Component 2 utilizes machine learning to extract and analyze data on fish ponds from satellite images. Combined with data collected under Component 1, this analysis facilitates development of an interactive, online data visualization tool that can be used to estimate aquaculture’s multidimensional contributions to the economy and nutrition, focusing on production, economic value added, and employment – all differentiated by gender and value chain segment. The publicly available web-based tool designed based on stakeholder consultations facilitates user interaction with and visualization of the data generated.

Component 3 is dedicated to formal training and outreach that builds individual, organizational, and societal capacity and includes 1) stakeholder consultations on features potential users wish to see incorporated into the interactive GIS interface; 2) a two-week data-analytics capacity-building retreat, to build host-country researcher capacity for quantitative survey data analysis, analytical thinking, and written and oral academic presentational skills; 3) dissemination of Bangla-language extension videos via social media; 4) a five-day remote-sensing capacity-building course for GIS users; and 5) workshops to promote new and emerging technologies to private sector actors and extension agents in each of the surveyed zones.

Role of homestead farming systems in the livelihoods and food security of poor farmers in southern Bangladesh

Areas in southern Bangladesh share common economic prospects but also challenges. The vast region is already undergoing adverse effects from natural disasters, such as tropical cyclones and accompanying storm surges. Integrated farming, with poultry, fish and crops, can play a significant role in increasing manifold production, income, nutrition and employment opportunities for rural populations in the southern part of the country.

Nutrition approaches in the Fish for Livelihoods project (Burmese version)

This document is a guideline about the nutrition approaches to be followed in Fish for Livelihoods project. Development and printing of communication materials on nutrition and WASH based on the Essential Nutrition Actions and Essential Health Actions messages; includes the importance on consumption of micronutrients rich small fish (SIS), farming SIS, etc.


Nutrition approaches in the Fish for Livelihoods project

This document provides a common understanding among stakeholders (staff from implementing partners, WorldFish staff, donors, communities) on the approaches undertaken throughout the project. These approaches are based on experience from other WorldFish projects, both in Myanmar and in neighboring countries. This document serves only as a guide, so feedback and recommendations from stakeholders are welcome.
