The annual global average catch shares of the anadromous Hilsa, Tenualosa ilisha of Bangladesh increased rapidly from 74.5% all through 1984–2013 to 86.7% during the 2010–2015 periods. With a few exceptions, an increasing trend of Hilsa production over the last three decades was found in Bangladesh. Initially three options incorporating digital image measurements were compared to determine the best method for obtaining accurate length data. The length-frequency data measured from digital images showed that Hilsa have a moderate growth rate (K = 0.90 year−1) of up to 58.70 cm (L∞) TL.

Social resilience is an essential aspect of sustainability in environmental management, especially in poor resource-dependent communities. To better understand the dynamics of social resilience, we have conducted a primarily qualitative study of communities dependent on hilsa fishing in two coastal villages in southern Bangladesh. This study applies concepts of social-ecological system (SES), social resilience and co-management in outlining our qualitative data and framing its interpretation.

As part of the project “Assessing economic and welfare values of fisheries in the Lower Mekong Basin” a large fish focused household welfare survey was initiated in 2012 by World Fish and CARDI.

Perception is the bed rock to really apprehend the assertiveness and interpretations of the farmers which are the grass root receptors or benefactors of the effects of climate change. Individual perception and knowledge on climate change varies according to geographical location, occupation, political and socio-economics, ecological, cultural background of the entity. Empirical observations and climate models both indicate that global climate and ocean conditions have been changing over the last 100 years and will likely change more rapidly in the future.

Diseases have been recognized as the major obstacle to the shrimp (Penaeus monodon) and prawn (Macrobrachium rosenbergii) aquaculture production in Bangladesh. This study provided an assessment of shrimp and prawn diseases/syndromes, health management practices, and occupational health hazards associated with the handling of chemical and biological products to prevent and treat shrimp and prawn diseases. A survey was conducted using a semi-structured questionnaire with 380 shrimp and prawn farmers in the southwest of Bangladesh during February and June of 2016.

Shrimp farming is an important income generating activity for hundreds of thousands of small scale farmers operating extensive ghers in Bangladesh. White spot syndrome virus (WSSV) has caused major shrimp production losses globally including Bangladesh. This study investigated the benefits of stocking WSSV infection free (WSSVF) Penaeus monodon post larvae (PL) to extensive gher holders of southwest Bangladesh and considered different parameters of the farming system.

The current study aims to compare the technical and economic performance of salted and fresh fish processing associated with Lake Nasser fisheries. Field interview approach adopted to collect data from twenty two fish processors in Aswan. The questionnaire collected data of socioeconomic of fish processing, inputs and output and allowed for estimation of operational costs and revenue for the processors. The study revealed that fresh fish processing is attractive business for some university graduates than salted fish processing.

To assess the performances of CBFM, the study articulates the investigation along 3 dimensions, namely the social, economic, and biological outcomes. The monitoring of these is made possible by the simultaneous use of two methodological tools, namely a household survey and a biological monitoring scheme. The household survey consists of a comprehensive socioeconomic questionnaire administered to a randomized selection of households residing in villages adjacent to 12 CBFM fisheries under investigation.
