INTRODUCTION
 What is freshwater aquaculture?
 Freshwater aquaculture: a composite culture system?
 Prospects in Bangladesh
KEY ASPECTS
 How technologically and resource-wise potent is
freshwater aquaculture?
 Effective mitigation measures have the capacity to
overcome the constraints associated with freshwater
aquaculture..
TYPES
Freshwater bodies encompass various types of water sources that
contain low salinity, typically less than 0.5 parts per thousand. Here are
some common freshwater bodies:



River
Streams
Lakes
Ponds
Reservoirs
Swamps
Floodplains etc.
FRESHWATER AQUACULTURE SYSTEMS
 Open culture system:
 Cage culture
 Pen culture
 Raft culture
 Rack culture
 Semi-closed culture system:
 Pond culture
 Raceway culture
 Closed culture system:
It involves no water exchange and necessitate extensive water treatment.
ADVANCED FRESHWATER CULTURE SYSTEMS
 Aquaponics:
• Combines raising fish in tanks
with soilless plant culture
• The nutrient-rich water from
raising fish provides a natural
fertilizer for the plants and the
plants help to purify the
water for the fish
 Recirculatory Aquaculture
System (RAS):
•
Water is recycled and reused
after mechanical and
biological filtration
ADVANCED FRESHWATER CULTURE SYSTEMS
 In-Pond Raceway System
(IPRS):
 Constant water circulates is
maintained for optimum water
quality and to improve feed
management
 Integrated multi-trophic
aquaculture(IMTA):
 Similar to polyculture
 Two or more organisms are farmed
together

FRESHWATER AQUACULTURE: MANAGEMENT
NEEDS FOR SUSTAINABLE AQUACULTURE
DEVELOPMENT
1. Responsibilities
 To understand the management needs a bottom-up approach has been made:
farmer's needs (technology, training and credit) are at the top and at the bottom
are the universities which take responsibilities to produce the required senior
manpower.
2. Institutional Collaboration and Curriculum Enhancement
Curriculum Development by Universities
Research Organizations' Focus on R&D
3. Strengthening Regulatory Oversight and Financial Support
 Strengthening Department of Fisheries
 Non-Governmental Organizations' Role
in Technology Adoption
 Coordinated
Banks
Efforts
 Coordination
Board
through
of
Commercial
DOF
Advisory
 Monitoring and Evaluation Wing
 Execution Wing for Implementation
4. Core Principles for Sustainable Freshwater
Aquaculture Management
 Environmental Stewardship
 Water Resource Management
 Market access
 Disease Prevention and Control
 Responsible Feed Management
 Community Engagement and Social
Responsibility
 Regulatory Compliance and
Governance
 International collaboration
