      Net cage culture of tilapia in dams and small farm reservoirs 

      DD Baliao, MA de los Santos, NM Franco & NRS Jamon - 2000 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Series: Aquaculture extension manual; No. 30
      The manual describes the net cage of tilapia in dams and small farm reservoirs, which has been found to be a low-cost yet high-income earning farm activity and offers an excellent option as an alternative livelihood for poor inland fisherfolks. The following aspects are covered: 1) Characteristics of a suitable site; 2) Design of the net cages - the floating cage, the stationary/fixed cage; 3) Stocking the net cages - source of juveniles, stocking rate, stocking time, acclimation; 4) Management of the cages - feeds and feeding, monitoring activities; 5) Harvesting - partial harvest, total harvest; and, 6) Profitability analysis.

      An assessment of the coastal resources of Ibajay and Tangalan, Aklan: Implications for management 

      LMB Garcia (Ed.) - 2001 - Aquaculture Department, Southeast Asian Fisheries Development Center
      This report describes the present state of marine resources in several coastal barangays of Ibajay and Tangalan, Aklan (Philippines). Field data were obtained from rapid surveys conducted from July to September 1998. Recommendations based on analyses of the data will guide fisherfolk and other stakeholders, particularly the local government units, in their development plans for these neighboring municipalities. Both land and marine products in the area are mainly harvested for the local market. All coastal barangays are dependent on fishing for their livelihood. The medium-scale municipal fishery of Tangalan employs several passive (encircling gill net, bag net, fish corral) and active gears (baby purse seine) compared with the traditional fishing methods employed by Ibajay fishers. Pond aquaculture in mangrove areas is well-developed in Ibajay West (barangays Aquino and Ondoy) and in Tangalan. However, ownership of these ponds is limited to a few individuals and families, unlike in Barangay Bugtong Bato where informal ownership distributed among families has been the traditional rule. Nonetheless, the introduction of so-called environment-friendly methods of utilizing mangroves (e.g., aquasilviculture) and other shared coastal resources may seriously undermine the informal rights-based social structures in the barangays. Without proper rules and enforcement, the application of these methods may be misused, aggravating the already poor overall state of their coastal resources. Major problems affecting their fishing livelihood include siltation of nearshore waters due to illegal deforestation upland, encroachment of municipal fishing grounds by commercial and other fishers elsewhere, and the lack of capital to finance the fishery. Weak inter-organizational links among government and non-government organizations have hampered the implementation of solutions to these common problems in coastal barangays. For instance, a conflict between fishers from these neighboring municipalities over territorial boundaries of common fishing grounds in Pangayawan and Pungtod reefs has not been resolved over the years. Likewise, the introduction of aquasilviculture in mangrove areas may become a potent source of conflict among resource-users who maintain informal rights over the mangrove resource. The overall state of coastal resources in these municipalities is in immediate need of a unified plan to promote both their preservation and conservation. To achieve this end, a joint resource management council representing all resource-users from both municipalities must be organized and convened. To address the presently weak inter-organizational links among existing organizations, this joint council may provide a legitimate forum to identify, resolve, integrate, implement, and enforce guidelines on the common use of resources, both marine and inland. Low estimated yields from the reef fishery, conversion of mangroves for aquaculture beyond the allowable limit, a persistent conflict over fishing rights in several reefs offshore, the limited resources for seaweed and fish mariculture, and threats on existing traditional social structures by progressive resource-users are several issues that require thorough discussions to formulate popularly approved and acceptable management strategies. These strategies include community-based approaches of co-managing resources such as "no-take zones" (sanctuaries), ecotourism development, and livelihood schemes to mitigate, in part, the pressure of over-exploitation of fishery resources.

      Grow-out culture of the Asian catfish Clarias macrocephalus (Gunther) 

      EB Coniza, MR Catacutan & JD Tan-Fermin - 2008 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Series: Aquaculture extension manual; No. 41
      Asian catfish Clarias macrocephalus is an esteemed food fish especially in Southeast Asia due to its tender and delicious meat. This commodity constitutes a valuable fishery for small-scale fishers in the region and has a great potential for aquaculture. The important considerations in the grow-out culture of catfish are reliable water supply, soil with good compaction properties for dike construction, supply of fingerlings, feeds, labor, pond supplies and technology assistance. The farm must also be accessible by road, near to market facilities and has a peaceful environment. Rearing catfish in ponds is the most popular and commonly practiced. The pen culture is a system fully enclosed by nets on all sides but utilizes the dug-out pond, dam or lake bed as bottom enclosure. Tanks in abandoned old hatcheries with freshwater source can be used for catfish culture. In the cage culture system the stock is fully enclosed by nylon nets on all sides and bottom similar to an inverted mosquito net installed in suitable areas like reservoirs, dams, lakes and dug-out ponds. The rice-fish (catfish) culture is also practiced where the rice pond canals are utilized to retain water at 1-2 m depth to provide shelter to the fish while the rice plot maintains 10-20 cm water depth. For the stock, select fingerlings that are active, healthy and uniform in size. Handling of fish stock is important to avoid mortality due to stress during harvest, sorting, counting and transport. Furthermore, stocking of fish is recommended during the cooler part of the day. Catfish fingerlings stocking density is about 5 to 20 pcs/m2 depending on the water supply and support facilities of the farm. The catfish, C. macrocephalus, requires a substantial amount of dietary protein for growth. For this species a formulated diet with crude protein (CP) of 34%, moist diet (trash fish or blanched chicken entrails plus rice bran or cooked broken rice), and a combination of pellet feeds (50%) and moist diet (50%) have been tested and acceptable for the grow-out culture. Economic evaluation based on a grow-out culture in pond with an area of 1,000 m2 showed that feeds and fingerlings are the major variable costs. The net income, return on investments and payback period, respectively range from PhP22,972-PhP35,741, 80-122% and 0.8-1.2 years when using pellet, moist feed or a combination of these feeds. Feeding using formulated diet has an advantage of convenience, quality and quantity over moist diet which has issues such as inconsistent supply, storage requirement and fouling the rearing water.
