Impact of small indigenous species of fish (SIS) on livelihood of local fishing community in two upazilas of Mymensingh

The fisher folk used to catch small indigenous species of fish (SIS) from rivers, canals, wetlands and floodplains at little or no cost for their livelihood. Surplus fish was sold at the local market to generate some little capital for the households. The livelihood and consumption of SIS in fishing community of two upazilas viz. Trisal and Ishwarganj under Mymensingh district were studied for 3 months in 2004. Most of the fisher folk of the study areas belong to resource-poor section of the society living below the poverty level. Majority of them had no cultivable land. As professional fishers they face many problems during lean fishing period from January to April due to little or non-availability of fish. Majority of the fisher households consumed SIS three to four days a week. The fisher households of Trisal upazila consumed more small fish than those of Ishwargonj upazila. More than 50% respondents consumed <20 g SIS/day and 20% consumed >40 g SIS/day in Trisal upazila. On the other hand, in Ishwargonj upzila, most of the fisher households (66%) were found to consume <20 g SIS/day. SIS was mostly available from July-December in rivers, wetlands (beels), and canals, and income from fishing was reported to be good. The dominant SIS was Puntius spp., Mystus spp., Anabas testudineus, catfishes, mola, and small prawns. Non-indigenous species like tilapia was also dominant in Trisal upzila where aquaculture practices were well established.

A characterization of community fish refuge typologies in rice field fisheries ecosystems

In rural Cambodia, fish is a source of food and income to millions of people. However, there has been a real threat to fish populations in natural wetlands due to the degradation of aquatic biodiversity and habitat, illegal fishing, increase of population and demand for fish, and the use of harmful pesticides for agriculture. The Rice Field Fisheries Enhancement Project (RFFEP) seeks to rebuild and protect the fish populations through innovative methods. The project works with communities to sustainably strengthen the rice field fisheries near their villages by improving protected habitats called "community fish refuges". This handbook characterizes rice field fisheries that are connected to community fish refuges. Community fish refuges are designated fish conservation areas promoted by the Fisheries Administration of the Royal Cambodian Government. It also examines the characteristics of rain-fed rice field ecosystems that are connected to community fish refuges in order to further refine descriptive criteria and better understand potential benefits and management strategies.

Community Based Fisheries Management (CBFM) in Sunamganj district of Bangladesh: the nature of cooperation and conflicts

There are altogether 411 haors comprising an area of about 8000 square kilometer, covering 25% of entire region dispersed in the districts of Sunamgonj, Sylhet, Moulvibazar, Hobigonj, Netrokona and Kishoreganj. Sunamganj district is particularly known as a district of haors and baors where a large number of people depend on fishing for their livelihood. Some people are basically fishermen and fish all the year round. Community Based Fisheries Management (CBFM) project has been initiated in this area to develop fishery sector as well as for the development of the inland fishermen of haor area. Healthy cooperation among the beneficiaries of the project is very much present and some NGOs are found working actively there to help the fishermen for the sound implementation of the project. But the influentials of different villages around create troubles and conflicts intentionally in the project area because of which fishermen cannot fish smoothly and the implementation of the project is getting hampered. Therefore, a kind of consensus needs to be reached among the inhabitants of the haor area and a powerful association of the fishermen should be established so that fishing may be undertaken in the beel without having any troubles and conflicts. In this article the conflicts and cooperation that are in existence in the implementation process of CBFM project in the haor areas of Sunamgonj district have been discussed. Some suggestions have been offered in the paper to overcome the existing conflicts impeding the smooth implementation of CBFM project in the fishery sector of haor area under Sunamganj district.

Enhancement of fish production in a reservoir after partitioning by dikes through community participation

A reservoir of 70 acres was portioned by dikes into four manageable big ponds to get more production of fishes at Basurhat, Noakhali, Bangladesh under the supervision of local community through a society of 40 people ownership. Pangus (Pangasius hypophthalmus) @ 20,000/acre, and then fry and fingerlings of different types of fishes such as catla (Catla catla), rohu (Labeo rohita), mrigal (Cirrhina mrigala), grass carp (Ctenophmyngodon idella), bighead (Aristichthys nobili), silver carp (Hypophthalmichthys molitrix), common carp (Cyprinus cmpio) and rajpunti (Puntius gonionatus) @ 500/acre were stocked. Feed containing 25% protein was used two times daily and feed was adjusted fortnightly. After 8 months, all the fishes were weighed 0.80-2.10 kg except rajpunti (150-200 g) and tilapia (150-220 g), and a total of 25 ton of fish was harvested which was five times higher than the previous production under signal ownership. The production of fishes were increased after partitioning the lake with dikes due to proper management and control.

Community-based tarball monitoring in the Maldives

Monitoring oil pollution by using students to count tarballs on beaches. Samples were taken between 2006 and 2010; a significant relationship was demonstrated between the abundance of tarballs and exposure to shipping lanes. The contribution of local communities to monitoring marine pollution was also demonstrated.

Review of community-based ICM: best practices and lessons learned in the Bay of Bengal, South Asia

Conclusions and recommendations of the report were based upon eighteen case studies of community-based Integrated Coastal Management (ICM) in Bangladesh, India, Maldives and Sri Lanka. These include empowerment of coastal communities; failure of imposed fishery co-operatives; and the application of territorial use rights in fisheries(TURF).

Benthic community survey of Gwadar (east bay) Balochistan, Pakistan

Benthic communities of the Gwadar east bay (Balochistan) was surveyed during the onset of S.W. monsoon. A total 1030 specimens were collected which represented Phyla of Arthropoda, Mollusca, Annelida, Echinodermata. The most abundant class observed was that of Bivalvia. Seawater parameters such as dissolved oxygen, temperature, pH, salinity together with sediment characteristics were measured. Analysis of variance between observed stations and fauna do not show any significant difference (P<0.05). The present observation forms a baseline study in the area.

Mangrove community structure survey

Highlights are given of a mangove community structure survey conducted in the coastal barangays of Carles, Panay Island, Philippines, in April 2003. The survey aimed to qualitatively describe the species composition, community structure and plant biomass of mangrove forests. The 13 sample sites showed a total of 18 mangrove species, dominated by Avicennia marina. The findings, which indicate a modest yet declining diversity of mangroves in Carles, reinforce the need for their protection and management. This is due not only to their importance as habitats for fish and shellfish juveniles that replenish stocks for capture fisheries and aquaculture, but also due to the fact that Carles is one of the few remaining areas in Panay where rare mangrove species can still be found.

Technology for the community: SEAFDEC-designed artificial reefs

An account is given of the fabrication and deployment of artificial reefs used in the SEAFDEC/AQD's Community Fishery Resource Management project, which focused on Malalison Island located in west Central Philippines. The project aimed to apply community-based techniques of fishery resource management through the collaboration of community organizations, biologists and social scientists. The 3 types of reefs (building blocks, concrete pipe culvert, and modified concrete pipe culvert) were deployed at Gui-ob reef covering an area of less than 1 ha.

Fish exploitation and changes in the fish community of Lake George, Uganda

Unlike Lake Victoria, the fisheries of Lake George have undergone gradual changes in the size and proportion of the major commercial fish species, the Nile tilapia (Oreochromis niloticus: cichlidae) in the last 40 years (1950-1989). The size decreased from an average weight of 900g in 1950 to 430g in 1989 while percentage contribution in commercial catches during the same period declined from 92% to 36%. The over all annual commercial catches though showed a steady increase from the period 1950 when the fishery was opened to intensive and controlled exploitation, consistently high catches were observed in the 1960s and 1970s followed by a general decline in the early 1980s to amore or less stable fishery in the late 1980s. These changes are attributed to increased fishing pressure especially on the nil tilapia and to increased use of smaller gill net mesh sizes lower than the recommended 127mm mesh. The changes in gill net mesh have brought O. leucostictus, acichlid, into commercial catches confirming that the 88.9mm mesh size nets are used by the commercial fishermen to harvest smaller fish species. The commercial catches are presently dominated by the piscivorous fishes,(over 60%) whose contribution was less than 10% during initial exploitation of the virgin fishery in 1950.The piscivorous fish are mainly caught using hooks and lines. The entire fishery is believed to be exploited close to the maximum. The above trends serve to show the impact of exploitation on fish species diversity. Quantitive and qualitative changes of the major fish species on lake George are due to exploitation pressure unlike Lake Victoria where it is a combination of both exploitations and impact of fish introductions. There has been no fish introduction in Lake George.

The potential of community fish refuges (CFRs) in rice field agro-ecosystems for improving food and nutrition security in the Tonle Sap region

The fisheries sector in Cambodia contributes 8%–12% to national GDP and 25% - 30% to agricultural GDP, with an estimated 4.5 million people involved in fishing and associated trades. Fish and other aquatic animals are important food sources, contributing an estimated national average of 60% - 70% of total animal protein intake. Of the 2013 total fish production, 550,000 metric tons were harvested from freshwater habitats, of which rice field fisheries and small-scale family fisheries contributed approximately 20%. The productivity and value of rice field fisheries to households in rural Cambodia has been highlighted in a number of previous studies. The Fisheries Administration of the Ministry of Agriculture, Forestry and Fisheries plans to increase productivity from rice field fisheries and aquaculture at an annual rate of 15% to maintain supply for a growing population. This report draws mainly on the baseline and monitoring data from the Rice Field Fisheries Enhancement Project (RFFEP) during its implementation between 2012 and 2014. Reference is also made to the Fish on Farms project to highlight the relative contribution of fish from small-scale aquaculture compared to wild-caught fish.
