There are currently 27 aquatic farms permitted to grow various species of seaweed in Alaska, with 12 farms permitted exclusively for kelp But not all permitted farms are actively growing seaweed, yet Most seaweed farming activity is concentrated around regional hubs (such as Kodiak-Sun’aq and Ketchikan-Kichx̱áan) where seed suppliers and processors are established With other hubs emerging near Cordova-Arwartuliq and Homer/Kachemak Bay-Qackimak.

    Case Study: Seaweeds, Marine Shrimp and Tilapia Fish

    Case study: Seaweeds Summary Successful commercial production of seaweed in the Pacific region is presently based on one single species of red algae, the species Kappaphycus alvarezii, being Solomon Islands, Fiji, Kiribati and Papua New Guinea the 4 main producer countries, with a total production for the region of around 20.000mt (wet weight) and more than 10.000 families involved. This species was introduced from the Philippines and Indonesia to most Pacific Islands Countries and Territories along the 80’s and 90’s. Other seaweed species that have been or are being tested within the region, we should mention the brown seaweed Cladosiphon sp., which is known to occur naturally in Tonga and New Caledonia, was cultured quite successfully in Tonga for many years, but farm- ing ceased in 2007 due to market difficulties. Other edible species, such as Cladosiphon sp., Caulerpa sp., Codium sp. and Gracilaria sp. are currently being grown in several Pacific Island countries in very low volumes (we could say almost anecdotally in most cases). Sea grapes (commonly known as sea caviar), such as the species Caulerpa rac- emosa, have been cultured in Samoa and French Polynesia since 2011 with promising results in terms of growth and survival rate. Three principal farming methods have been tried in the Pacific Islands region: 1) off-bot- tom (fixed monofilament lines between posts driven into the substratum); 2) floating rafts (bamboo floating structure); and 3) floating long-lines (rope-made floating structure). Commercial cultivation in Fiji, Kiribati, Papua New Guinea and Solomon Islands consists almost entirely of off-bottom farming.

    Seaweed Farming: an Alternative Livelihood for Small-Scale Fishers?

    06/27/02 Seaweed Farming: An Alternative Livelihood for Small-Scale Fishers? By: Brian Crawford Program Manager, Asia ([email protected]) Working Paper 06/27/02 Seaweed Farming: An Alternative Livelihood for Small-Scale Fishers? By: Brian Crawford Abstract Development of alternative livelihoods has become a popular policy to uplift the socio- economic status of small-scale fishers and to reduce fishing pressure on overexploited fisheries. Seaweed farming has been incorporated into many community-based coastal resources management projects and fisheries management initiatives as an alternative livelihood option for fishers in tropical developing countries. This is typically based on several assumptions, either unstated or explicit, of program designers, project managers and senior policy makers. First, it is often assumed that small-scale fishers are poor and that this is related in many cases to the overexploited nature of the resource. Secondly, it is assumed that fishers are willing to give up fishing in favor of more lucrative economic opportunities, such as seaweed farming. Lastly, it is assumed that as fishers take up alternative livelihoods such as seaweed farming, this will reduce pressure on the fisheries. This is an excellent example of a project logic framework whereby certain inputs (e.g. promotion of seaweed farming) will lead to specific outputs (e.g. improved socio- economic status of fishers, reduced fishing pressure and improved resource status). This paper will examine the evidence underlying these assumptions and the extent to which development of seaweed farming as an alternative livelihood can increase socio- economic status of fishers and reduce fishing pressure based on a number of examples from coastal communities in North Sulawesi, Indonesia.

  • Social and Economic Dimensions of Seaweed Farming: a Global Review

    Social and Economic Dimensions of Seaweed Farming: a Global Review

    IIFET 2012 Tanzania Proceedings SOCIAL AND ECONOMIC DIMENSIONS OF SEAWEED FARMING: A GLOBAL REVIEW Diego Valderrama, Food and Resource Economics Department, University of Florida, USA, [email protected] ABSTRACT Seaweed farming based primarily on the culture of Kappaphycus and Eucheuma species has grown significantly in the Philippines and Indonesia over the last two decades, with growth also taking place at a smaller scale in Tanzania, India and a few other developing countries. Unlike other forms of aquaculture, seaweed farming foregoes the use of feed and fertilizers and has minimum technological and capital requirements. In addition, growout cycles are short, normally lasting less than two months. Given these unique characteristics, seaweed farming has generated substantial socio-economic benefits to marginalized coastal communities in developing countries, most of which have reduced access to alternative economic activities. In some communities, seaweed farming has emerged as the most relevant livelihood strategy. This paper summarizes the findings of a recent FAO review on the social and economic dimensions of seaweed farming in six countries in Asia (the Philippines, Indonesia, India), Africa (Tanzania), Oceania (Solomon Islands), and Latin America (Mexico). Each case study documented the evolution of the farming sector and examined the mix of public sector policies and private sector involvement leading to growth of the activity. Given the rising global demand for seaweed-derived products, seaweed farming has the potential to generate further socio-economic benefits to coastal communities in tropical regions; however, a number of challenges and constraints (some of which are country-specific) will need to be addressed to fully take advantage of these opportunities.

    Case Studies with Pictures

    Case #1: An open ocean mussel farm in Southern California ● Mussels grow on ropes that hang from rafts 7 miles offshore. ● Mussels are filter feeders, filtering plankton from the water to eat, as well as filtering out pollutants in the ocean. Farmers do not need to buy food for the mussels because they get it naturally from the ocean. ● The ropes can create a habitat, becoming a home for other organisms such as barnacles, sponges, and algae. ● Mussels produce thousands of offspring per year and grow relatively fast. Case #2: An enclosed open ocean Atlantic salmon pen in Scotland ● Salmon are enclosed in a pen that sits in the ocean ● Salmon are fed food pellets that are made of other ground up fish species and vitamins. The salmon farmers buy the pellets from a different part of Europe. ● This farm is a monoculture, meaning there is only one species grown. ● Since it is a monoculture, there are no detritovores to clean up the fish waste. The fish swim in their own waste and sometimes it flows out of the pen and into the environment. ● There is little genetic variation amongst the salmon (they all have similar DNA), so one disease could kill all the fish. ● Those diseases from the farmed fish could spread to the wild fish. Case #3: A coastal seaweed farm in Japan ● Seaweed grows from ropes that are suspended in the ocean, close to shore. ● Seedlings are transplanted onto the ropes and grow relatively quickly after that. ● A large, open space is required for seaweed farming. Farmers had to cut down a mangrove forest to make room for the farm.

    Shading Effect of Seaweed Farming on the Growth and Health of the Corals

    Shading effect of seaweed farming on the growth and health of the corals Porites cylindrica and Acropora formosa 1Parman Parakkasi, 2Rajuddin Syamsuddin,2Najamuddin, 3Abdul Haris, 3Chair Rani 1 Doctoral Program in Fisheries Science, Faculty of Marine Science and Fisheries, Universitas Hasanuddin, Makassar, Indonesia; 2 Department of Fisheries, Faculty of Marine Science and Fisheries, Universitas Hasanuddin, Makassar, Indonesia; 3Department of Marine Science, Faculty of Marine Science and Fisheries, Universitas Hasanuddin, Makassar, Indonesia. Corresponding author: C. Rani, [email protected] Abstract. The objective of this study was to analyze the effect of shading from seaweed farming on coral growth and health. The study applied an in-situ experimental approach, placing 3 replicate seaweed farming plots with an area of 40x30 m2 (floating longline system; 30 m lines with 0.5 m spacing) in a coral reef area, with a control area of approximately 50 m from the plots. Seaweed seedlings (±100 g) were attached 0.2 m apart. In each plot and the control area, colonies of two branching corals, Porites cylindrica and Acropora formosa (10 of each species) were tagged on a principal branch. The growth of the selected branches was measured every 2 weeks during a 6-week observation period. As an indicator of coral health, colony color was recorded using a standard coral health index monitoring chart. The t-test was used to analyze the effect of shade on coral growth and coral health, comparing coral colonies shaded by seaweed cultivation with unshaded corals (natural conditions). There was no significant difference in the growth and health level of the 2 coral species between colonies living in the seaweed farming area and in natural conditions (control).
