In 2017, local data-collectors recorded information on fish catches in 12 villages in Malaita Province, representing the main littoral habitats and zones. A total of 10,583 fishing trips were recorded over a period of 14 months, yielding 340 marine species. Data was collected in the framework of the ADB-funded project ‘Strengthening community-based natural resource management to safeguard food security in Malaita Province’ (TA 7753).
The dataset was collected from a sub-sample of private firms providing aquaculture services and products in Lusaka and Southern Provinces of Zambia, where the bulk of medium-to-larger scale private firms are located. The private firms identified for this assessment refer to key commercial players along the aquaculture value chain that are active and have the potential to invest in developing the aquaculture sector in Zambia, and specifically to be an important source of employment for students training in Fisheries Science at TEVET and higher-learning institutions.
Evaluation of Oxford Nanopore Technology Minion for genome sequencing of aquatic pathogens. Folder contains a curated, complete reference-quality genome of Streptococcus iniae, an important bacterial pathogen of tilapia and other warm water fish species, assembled from PacBio and Illumina HiSeq data. The same strain (QMA0248) was sequenced using ONT Minion and an assembly prepared from subsampled reads to provide ~100 fold coverage. For comparison, alignment of the two assemblies was performed in progressive mauve single nucleotides polymorphisms (SNPs) called.
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.
