| Today, the seaweed industry's main products are the alginates and carraghenanes. The industrial network faces many problems. However, it remains prosperous since it ranks fifth in the world for alginate production and third for caraghenanes'. This stability which seems safe on a middle term standpoint must not conceal the crisis which previously hit Fucus' exploitation. Rightly so, being harvested until approximately 1950 for soil amendment purposes, coastal kelp (i.e. Fucus), was replaced by chemical fertilizers. Brittany's production which was reaching 180 000 cubic metre in the twenties, close to 200 000 tons of fresh kelp, would have become non existent if it had not been converted into seaweed meal for livestock feed. The market demand was then... |

| En 1987, la filière de production de chevrettes Macrobrachium rosenbergii en Guyane Française a fait l'objet d'intervention du laboratoire d'aquaculture de l'IFREMER à 2 niveaux : un appui technique à la profession, et des expérimentations à la station expérimentale gérée en commun par IFREMER et INRA, à KOUROU. L'appui technique a porté sur la formation d'éleveurs notamment pour le démarrage des exploitations, l'amélioration des techniques d'exploitation et de choix des classes détaillées commerciales, la maîtrise des caractéristiques du milieu d'élevage par l'utilisation des amendements classiques, la lutte contre la contamination des produits par les germes coliformes. Le programme de recherche a porté en 1987 sur l'analyse du milieu d'élevage et tenté... |

| Agricultural lenders have a stake in and are in a position to influence their borrowers' management decisions. Risk management practice adoption is an area in which lenders might want to exercise this influence. This study employs logistic statistical models to estimate lenders' influence on crop producers' decisions regarding use of three alternative risk management practices: federal multiple-peril crop insurance, crop hail and fire insurance, and forward contracting. Results suggest lenders can exert significant influence on these decisions but that poor communication between lenders and borrowers likely reduces this influence. |

| This paper presents a quantitative analysis of the Chinese wheat and rice industries. The specific purpose is to analyze government policies for wheat and rice, and their impacts on industry performance. Dynamic relationships among prices, quantities and total GNP are investigated with a vector autoregression using Chinese data. Government intervention in domestic commodity markets is quite common in China. The Chinese government is not only heavily involved in production, but also in marketing and distribution of most commodities, especially agricultural products. Production planning and collection rationing are used to reduce the need for food imports. Grain price policy is used as an economic tool to promote the government's objectives of... |

| Specialty crops have been cited as means to diversify crop portfolios on the prairies. Lentils, a specialty crop, have high variability in yields and prices but are relatively uncorrelated with the yields and prices of other traditional Saskatchewan crops. In addition, yields and prices of lentils may be negatively correlated. These attributes have important but offsetting effects in crop portfolio selection. The objective of this article is to assess the relative profitability and riskiness of wheat and lentil rotations for a representative Saskatchewan farm and to select appropriate farmers who should consider production of lentils. The cumulative density function of net returns are simulated for both rotations assuming stochastic prices and yields.... |

| This paper provides an economic analysis of the historical agricultural price and income support policy, a policy of market-determined prices and income, and a policy linking market-determined prices with sector-wide farm income stabilization in years of economic disaster. The analysis compares commodity prices, net farm income, and government expenditures over the period 1970 through 1982 based on estimates generated by USDA's Food and Agricultural Policy Simulator (FAPSIM). The historical policy generates the highest income and most stable prices. Market-determined income is lowest and has the greatest variability. Stabilization minimized income variability at intermediate income levels. |

| A sequential decision-making model was developed, and data from farm-raised catfish production were used to demonstrate its use. Outcomes of sequences of decisions which satisfied chance constraints on ending cash balances were traced through a specified time period. Discrete choice variables were specified due to the fixed nature of pond facilities. Recourse actions specified were sale of production in excess of endogenously determined transfer levels or purchase of inputs to supplement needs of the next production stage. Production activities cannot be changed during the planning period. Only yield variability was considered due to its impact on relative competitiveness among growth stages. Deviations were calculated from endogenously determined target... |
