Cross-Hedging Fishmeal: Exploring Corn and Soybean Meal Futures Contracts

During 2006 the fishmeal price nearly doubled from $500MT to over$900MT. The objective of this research is to determine the optimal cross-hedge ratio between fishmeal and soybean meal and corn, and corresponding hedging weight between corn and soybean. Results indicate all hedging weight should be placed on the corn futures contract. This is an interesting result since prior fishmeal cross-hedging research has not analyzed the corn futures contract as a risk management mechanism.Crop Production/Industries, Risk and Uncertainty,

Growth response of Heterobranchus longifilis (Valenciennes, 1840) fingerlings fed raw and boiled Mucuna cochinchinensis seed meal

Feeding trial was conducted in static water to assess the growth of H. longifilis fingerlings fed different I inclusion levels of mucuna seed meal (MSM). Raw and boiled MSM were used in the diets at 10%, 20%, 30% and 40% inclusion levels and the performance of fish fed these diets was compared with fish fed a fishmeal-based diet which contained 40% protein. All diets were prepared to be isonitrogenous and isocaloric A two by five factorial experiment with three replicates using ten fish of average initial weight 1 .46g was carried out. Daily fish ration of five percent body weight was administered two times for eight weeks. The specific growth rate in diets 1 (control) and 6(10% boiled MSM) were similar and significantly (P<0.05) higher than the other dietary groups. The significantly lower growth performance of fish fed diets containing higher inclusion levels of both raw and boiled MSM might be due to incomplete elimination of the antinutritional factors present in MSM by boiling. Other methods of processing MSM to improve its nutritive value should be investigated. (7 page document

Estimation of growth and financial analysis through the application of Ipil ipil (Leucaena leucocephala) leaf meal as supplements to soybean and fish meal in the diet of juvenile monosex tilapia (Oreochromis niloticus)

Among plant protein ingredients,ipil ipil (Leucaena leucocephala) leafmeal (ILLM) is considered the most nutritive plant protein source after soybean meal in aquatic feeds. That was proven in a 21-day experiment conducted to assess the response of juvenile Monosex Nile tilapia Oreochromis niloticus with four iso-nitrogenous formulated diets: One control diet was formulated based on fishmeal, one on soybean meal and one on rice bran, ipil ipil leafmeal was also included in experimental diets

The effect of fishmeal or peameal on milk fatty acid composition in organic farming

Feed fatty acid (FA) composition influences the FA composition of cow milk. In a continuous production experiment with 32 Norwegian red dairy cows fishmeal (FM) was compared to peameal (PM) as protein supplement to home-grown cereals and grass silage in organic farming. The protein supplements were together with cereals formulated to be isonitrogeneous and isoenergetic (NEL) and were compared at high (HC) and low concentrate (LC) level. The concentrate rations did not affect the intake of silage. Fishmeal resulted in significantly higher milk yield (kg) with a lower fat concentration (HC) compared to PM. Lower concentrations of urea and FFA were found in milk produced with FM compared to PM. Milk flavour and odour was equal or better when FM rather than PM was fed. Fishmeal diets increased significantly the proportions of several long-chain FAs: oleic acid (C18:1c9), vaccenic acid (C18:1c11), CLA (C18:2c9,t11, not significant at HC), C20:0, C18:1t10, and DHA (C22:6 n-3) in milk fat compared to PM. DHA, which is found in high concentrations in FM (14 g/100g FAME), had the most significant increase. The proportion of C18:3 n-3 (ALA) was significantly lower when FM was fed compared to PM. The percentage of saturated FA was significantly lower and the percentage of monounsaturated FA was higher when FM rather than PM was fed. For cows on HC the n-6/n-3 ratio was lower in the FM group than in the PM group, and the ratio was lower at LC than at HC (p = 0.006, interaction p = 0.02). Fishmeal diets included higher proportions of oats than PM diets. Oats have high content of oleic acid and may therefore have influenced the composition of FAs in milk fat as well as the protein supplements. Fishmeal increased the proportion of beneficial FAs without reducing the sensoric quality of milk. It remains unclear whether this is an effect of protein source or an effect of the higher oat proportions in FM diets

Catch Shares in Action: Peruvian Anchoveta Northern-Central Stock Individual Vessel Quota Program

The Peruvian Anchoveta Northern-Central Stock Individual Vessel Quota Program is a catch share program that manages the largest volume fishery in the world. The goals of the program were focused on the economic improvement of the fishery through reduction of fleet capacity and lengthening of the fishing season. Additional biological and social goals were identified and seen as vital to ensure program success. Key design elements include restrictions on transferability to help limit consolidation and an industrysponsored social fund to assist with crew retirement and labor transition. To reflect the short-lived nature of anchoveta, management is structured into two fishing seasons per year. Each year, a five million metric ton reserve of anchoveta biomass is set aside to promote long term stock health

Growth response of Heterobranchus longifilis fingerlings fed with varying levels of dietary freshwater mussel (Aspatharia sinuata)

A common bivalve: Freshwater mussel, Aspatharia sinuate was evaluated as a dietary protein supplement in the production diet for Heterobranchus longifilis fingerlings with mean body weight 8.34 plus or minus 10g reared in aquaria tanks. Four diets containing fishmeal protein at a rate of 25%, 50% and 75% along with the freshwater mussel flesh were formulated. The diet without the freshwater mussel served as the control. The fish fingerlings were fed at 5% body weight per day for 56 days. It was revealed at the end of the experiment that freshwater mussel was most suitable as a protein supplement when incorporated at 25% replacement. The body weight gain, specific growth rate and feed conversion ration values of 6.83g, 1.06% day and 0.62 respectively were highest in diet with 25% replacement closely followed by diet with 50% replacement. Beyond 75% inclusion level there was no significant growth (P>0.05). However, complete replacement of fishmeal by freshwater mussel decreases growth rates and should not be used in Heterobranchus longifilis diet

Organic Aquaculture – the link between sustainable production and superior products

The first Danish organic rainbow trout with the Danish red Ø label was introduced to the market in 2005. The demand for organic trout is increasing and Danish trout farmers are currently con¬verting to organic production. However, the development of organic trout production in Denmark has been challenged by a very strict national legislation for organic aquaculture production. The objectives of the research include the most critical areas in the chain that forms the link between organic feed production, organic fish rearing, and the consumer. The main focus is on organic fish feeds in which non-renewable fishmeal is partially replaced by sustainable organic vegetable proteins

Substituting fish meal with grasshopper meal in the diet of Clarias gariepinus fingerlings

The effect of inclusion of grasshopper meal on the growth, feed conversion ratio and survival of Clarias gariepinus fingerlings of mean weight 9.71g was investigated. The results show that the best growth and food utilization indexes were recorded in the fingerling fed with 10% grasshopper meal and 30% fish meal, while the poorest growth and food utilization indexes were recorded with the diet containing 25% grasshopper meal and 15% fish meal. The best survival of 100% was observed in the diet containing 30% grasshopper meal and 10% fish meal while the worst survival of 73.3% was observed in the diet containing 25% grasshopper meal and 15% fish mea

Fish to 2020: supply and demand in changing global markets

Using a state-of-the art computer model of global supply and demand for food and feed commodities, this book projects the likely changes in the fisheries sector over the next two decades. As prices for most food commodities fall, fish prices are expected to rise, reflecting demand for fish that outpaces the ability of the world to supply it. The model shows that developing countries will consume and produce a much greater share of the world's fish in the future, and trade in fisheries commodities will also increase. The authors show the causes and implications of these and other changes, and argue for specific actions and policies that can improve outcomes for the poor and for the environment.Supply balance, Trade, Aquaculture, Fishery management, Economic analysis, Environmental factors, Developing countries
