Ndebele-Murisa PhD, Biodiversity and Conservation Biology Department, University of the Western Cape Analysis of temperature, rainfall and evaporation records over a 44-year period spanning the years 1964 to 2008 indicates changes in the climate around Lake Kariba. Mean annual temperatures have increased by approximately 1.5oC, and pan evaporation rates by about 25%, with rainfall having declined by an average of 27.1 mm since 1964 at an average rate of 6.3 mm per decade. At the same time, lake water temperatures, evaporation rates, and water loss from the lake have increased, which have adversely affected lake water levels, nutrient and thermal dynamics. The most prominent influence of the changing climate on Lake Kariba has been a reduction in the lake water levels, averaging 9.5 m over the past two decades. These are associated with increased warming, reduced rainfall and diminished water and therefore nutrient inflow into the lake. The warmer climate has increased temperatures in the upper layers of lake water, the epilimnion, by an overall average of 1.9°C between 1965 and 2009. -

Fishery Basics – Seafood Markets Types of Fishery Products
Fishery Basics – Seafood Markets Types of Fishery Products Fish products are highly traded and valuable commodities around the world. Seafood products are high in unsaturated fats and contain many proteins and other compounds that enhance good health. Fisheries products can be sold as live, fresh, frozen, preserved, or processed. There are a variety of methods to preserve fishery products, such as fermenting (e.g., fish pastes), drying, smoking (e.g., smoked Salmon), salting, or pickling (e.g., pickled Herring) to name a few. Fish for human consumption can be sold in its entirety or in parts, like filets found in grocery stores. The vast majority of fishery products produced in the world are intended for human consumption. During 2008, 115 million t (253 billion lbs) of the world fish production was marketed and sold for human consumption. The remaining 27 million t (59 billion lbs) of fishery production from 2008 was utilized for non-food purposes. For example, 20.8 million t (45 billion lbs) was used for reduction purposes, creating fishmeal and fish oil to feed livestock or to be used as feed in aquaculture operations. The remainder was used for ornamental and cultural purposes as well as live bait and pharmaceutical uses. Similar to the advancement of fishing gear and navigation technology (See Fishing Gear), there have been many advances in the seafood-processing sector over the years. Prior to these developments, most seafood was only available in areas close to coastal towns. The modern canning process originated in France in the early 1800s. Cold storage and freezing plants, to store excess harvests of seafood, were created as early as 1892. -

However, bivalve industry growth is falling behind fish aquaculture due to critical problems Food security in the production process.

Frozen shrimp continues to be the item of highest demand in foreign markets. Individual quick frozen (IQF) prawns which are indeed value added products and have already penetrated international markets elicit export incentive from development agencies like the Marine Products Export Development Authority. With the projected potential of 1.8 lakh tonnes of cephalopods against the current yield . of 13,000 tonnes, there are good prospects of increasing exports of frozen &;JUid and cuttlefish. The technology of packing fish in retortable pouches as an alternative to canning has now been perfected. Salted fish mirice has good market potential within the country and abroad. Diversification of fish products which are acceptable to larger fish consuming communities would alone ensure profitable utilization of our marine resources. INTRODUCTION India's total marine fish ·landings amount to 1.53 million metric tonnes against the harvestable resource of 4. 5 million ton nes projected potential. Of the landings, just over 65% are con sumed in fresh condition, about 20% converted· into salted and dried products, 4% reducted into fish meal and 7% made into frozen products which almost exclusively go for export purpose. -
Resources for Fish Feed in Future Mariculture
Vol. 1: 187–200, 2011 AQUACULTURE ENVIRONMENT INTERACTIONS Published online March 10 doi: 10.3354/aei00019 Aquacult Environ Interact OPENPEN ACCESSCCESS AS I SEE IT Resources for fish feed in future mariculture Yngvar Olsen* Trondhjem Biological Station, Department of Biology, Norwegian University of Science and Technology, 7491 Trondheim, Norway ABSTRACT: There is a growing concern about the ability to produce enough nutritious food to feed the global human population in this century. Environmental conflicts and a limited freshwater supply constrain further developments in agriculture; global fisheries have levelled off, and aquaculture may have to play a more prominent role in supplying human food. Freshwater is important, but it is also a major challenge to cultivate the oceans in an environmentally, economically and energy- friendly way. To support this, a long-term vision must be to derive new sources of feed, primarily taken from outside the human food chain, and to move carnivore production to a lower trophic level. The main aim of this paper is to speculate on how feed supplies can be produced for an expanding aquaculture industry by and beyond 2050 and to establish a roadmap of the actions needed to achieve this. Resources from agriculture, fish meal and fish oil are the major components of pellet fish feeds. All cultured animals take advantage of a certain fraction of fish meal in the feed, and marine carnivores depend on a supply of marine lipids containing highly unsaturated fatty acids (HUFA, with ≥3 double bonds and ≥20 carbon chain length) in the feed. The availability of HUFA is likely the main constraint for developing carnivore aquaculture in the next decades. -

Please do not cite without agreement of | the authors I. Introduction Fish from Lake Malawi are a major source of animal protein for large numbers of people in Malawi and Mozambique, two of Sub- Saharan Africa's poorest countries. It is estimated that fish, supplied by a dynamic and diverse small-scale African fishing industry, contribute seventy percent of animal protein consumed by Malawians per year (Alimoso et al. 1990). In this paper we briefly discuss the scale and social organization of fishing and what we have learned about use rights in the southern and central portions of Lake Malawi. We propose that the open access fishing which exists in these areas has not significantly harmed fish stocks to date, although problems may be emerging. An equal, if not greater, threatjto the fish, fishing and the ecology of Lake Malawi than that posed by open access small-scale fishing originates from developmentalists— internal and external actors advocating large-scale, capital intensive exploitation of the fish and the development of an international tourism industry. -
Final Report
FINAL REPORT EXTERNAL EVALUATION of the Research, Monitoring and Development Project of Fisheries in the Cahora Bassa Reservoir – Phase II 2007-2010 Republic of Mozambique Ministry of Fisheries JUNE , 2010 Final Report: External Evaluation of the Research, Monitoring and Development Project of Fisheries in the Cahora Bassa Reservoir – Phase II EXECUTIVE SUMMARY I. INTRODUCTION The Research, Monitoring and Development Project of the Fisheries in the Cahora Bassa Reservoir – Phase II (a.k.a., Phase II or Project in this Evaluation) is a collaborative effort between ICEIDA and the Ministério das Pescas (MP, or Ministry of Fisheries) of the Government of Mozambique (GoM). Within MP, the Instituto Nacional de Investigação Pesqueira (IIP) is the implementing institution and is responsible for promoting scientific management of fisheries resources in Mozambican waters. ICEIDA commissioned an independent Evaluation of the Phase II Project in June 2010. This report presents the findings of the Evaluation Team. The Phase II Project was formulated in 2006 and implemented in 2007 as a complementary continuation of the very successful Phase I, conducted 2003–2005 that principally concerned the kapenta fishery and capacity development at Cahora Bassa. The objective of Phase II was stated as: The Project is a research-based project aimed at producing management options for the three fisheries, the semi-industrial, the Artisanal and the sport fisheries on the Cahora Bassa reservoir with the objective of minimizing fisher conflict and at the same time optimizing the harvest from Cahora Bassa. The specific objectives were defined in the Project Document (PD) as: 1. Strengthening the infrastructure and research facilities of the IIP delegation in Songo; 2. -
