Sea Cage

Commercial salmon farming in the Maritimes shows potential as a source of rural employment, growth, and foreign exchange. Canada lags behind most advanced countries in developing its aquaculture industry; Atlantic salmon (Salmo salar) might be one species in which Canada has a comparative advantage and in which Canada's late start might be overcome. This paper evaluates sea pen salmon culture by a number of criteria, including financial feasibility, and concludes that salmon farming can be profitable, contribute to growth, absorb labour, and earn foreign exchange. A final section explores policy options available to governments and to private sector producers.

Late Maturation

The sexual maturation of Atlantic salmon Salmo salar is a multifactorial process in which fish acquire somatic characteristics to reproduce. In salmon farming has been described a high variability in the trait age at maturation derived from wild reproductive strategies. Early maturation is a phenotype that generates serious economic repercussions on both, sea cage and on land-based aquaculture systems. In view of the challenges of this problem for the global salmon farming industry, it is essential to thoroughly understand the influencing factors of early and late maturation to find efficient alternatives for managing the phenomenon. This review briefly describes sexual maturation in S. salar, its variability in cultures, and the factors influencing the maturation age trait at the physiological, genetic and environmental levels. The control of early maturity through changes to the natural photoperiod and through the use of genetic markers are discussed.

Aquaculture Industry

Abstract Aquaculture is currently one of the most rapidly growing food production industries in the world. The increasing global importance for this industry stems primarily from the fact that it is reducing the gap between the supply and demand for fish products. Commercial aquaculture contributes significantly to the economies of many countries since high-value fish species are a major source of foreign exchange. This review looks at the aquaculture industry, the issues raised by the production of fish through aquaculture for food security, the sustainability of the practice to agriculture, what the future holds for the industry in the next 10-20 years, and why there is a need to have available analytical procedures to regulate the safe use of chemicals and veterinary drugs in aquaculture.

The Impact

Abstract In Norway, there have been restrictions on salmon farming in several fjords to reduce the potential negative impact on important stocks of wild Atlantic salmon. Little is known about the incidence of escaped farmed salmon in fisheries and broodstocks relative to the extent of fish farming in nearby areas. In this study, we analysed data on the incidence of escaped farmed Atlantic salmon in angling catches and broodstock fisheries in rivers for a 16-year period (1989–2004). These data were weighted using official catch statistics and combined at the county level, and the incidence of escapees was correlated with both the stock of farmed salmon in net pens and the reported number of escapees in different Norwegian counties. Our results indicate a significant positive correlation between the incidence of escaped farmed salmon in the rivers at the county level and the intensity of salmon farming, measured as the number of farmed salmon in net pens, suggesting that protection areas may reduce the impact of escapees in salmon populations nearby.

Prospect of Cocoa Farming Development in Pangsan Village, Petang Sub-District of Badung Regency Cocoa plays an important role for the national economy, especially openingemployment opportunities, sources of income, and foreign exchange. The objectivesof this research are: to investigate the suitability of land for cocoa farming inPangsan Village, financial feasibility of cocoa farming in Pangsan Village, seen frominvestment criteria, and market prospect of cocoa commodity of Pangsan Villageproduction. The analysis used in this research is investment criteria method includingNPV, IRR, and Net B/C for financial feasibility analysis, while land suitability andmarket prospect are analyzed descriptively and qualitatively. The findings of thestudy showed that : land in Pangsan Village is appropriate (S2) for cocoa farmingand it has low productivity compared to cocoa productivity in Bali and Indonesia,cocoa farming in Pangsan village which is intercropped with coconut and bananatrees is financially feasible to be cultivated, with NPV of Rp 29.454.914,86, IRR of38%, and Net Benefit Cost Ratio (Net B/C) of 7,68, and the market prospect of cocoaproducts in Pangsan Village is not prospective for foodstuff, because the product ofcocoa produced is not fermented and not certified.

Livestock Products

With the rapid increase in consumption of some livestock products in Indonesia, expansion of domestic production of these commodities may enhance smallholders' incomes, increase rural employment and add to the country's trade balance. Policy analysis matrices (PAMs) were constructed to estimate divergences between private and social costs and returns in poultry and pig production in selected regions of Indonesia. In each case, producers' use of capital was subsidised but feed input private costs exceeded social values, and output prices received by producers fell short of values based on world prices. Production of all products as import substitutes was socially profitable, but in many instances private returns to farmers were negative. Product price and feed cost divergences were the major policy-induced distortions. Reform of these policies was estimated in a static partial equilibrium framework to lead to supply expansions of each livestock product, a contraction in livestock product consumption, and therefore additional net foreign exchange earnings from the poultry and pig sectors of around $320 million.
