Black Soldier Fly, a future for Tilapia feed?

(aquafeed.co.uk) With the increase of the fishmeal and soybean prices over the last decade, insect proteins have become a focus of research into novel alternative livestock feed ingredients. While several insect species have been investigated, the Black Soldier Fly (BSF; Hermetia illucens) remains one of the most credible options.

BSF, generally considered as a non-pest species, is distributed almost worldwide since the Second World War and is not known to carry any pathogenic agents, unlike the common housefly (Musca domestica).

The larvae can grow quickly and have an excellent feed rate. They can consume 25-500 mg of fresh matter/larva/day and feed on a wide range of substrates ranging from manures to food waste. A grow-out cycle takes 15 days to an average larva weight of 0.25g under optimal conditions (30oC) and the substrate/ waste load reduced by up to 70 percent (dry matter basis). The maggots have also been shown to remove pathogenic bacteria, reduce waste odours and to inhibit nuisance housefly oviposition; all valuable secondary sanitation outcomes.

The larvae have a high nutritional value; contingent on the substrate they were bred on, with crude protein levels ranging from 28 to 48 percent, and lipid levels from 12 to 42 percent. With the exception of omega-3 fatty acid, the lipid profile is broadly similar to fish meal and potential exists to augment fatty acid through the use of an appropriate feeds e.g. fish-offal. The essential amino acid profile of the insect meal meets the broad requirements of tilapias simplifying dietary formulation requirements……..

THE “INFANT INDUSTRY “- FLOATING FISH CAGES IN LAKE VICTORIA.

Aquaculture without borders is going to point out some issues based on already numerous reports and news  regarding floating fish cages in lake victoria.

According to professor Wellington Otieno , Findings show that cage aquaculture is a viable business on Lake Victoria, far better than use of canoes to hunt for wild fish while (Businesstoday)  noted that, this idea began as a solution to the plummeting fish populations in Lake Victoria,but the growing popularity of cage fish farming is now posing environmental problems of its own.  The practice could be harming the lake’s ecosystem due to the lack of guidelines to regulate it. The government promoted cage fish farming to address the diminishing fish stocks in the Lake – especially the tilapia species – whose shrinking numbers can only be described as catastrophic.

(News.mongabay): Fishermen, researchers, and government officials alike are
embracing cage aquaculture as a way to boost profits and fish supplies,
as well as give the lake’s free-swimming fish a reprieve.
However, cage fish farming has caused problems elsewhere in the world,
in part due to the use of chemicals and the release of waste products, such as dead fish, uneaten feed, and feces.

This “Gold rush” – to do cage farming in lake victoria has led to collaborative efforts
between KMFRI and its counterparts in Uganda and Tanzania to develop guidelines and policies that will govern cage aquaculture on Lake Victoria, which is a shared resource for the three countries.

Aquaculture without borders advocates for sustainable responsible aquaculture,
therefore the move by different institutions to develop New guidelines for this new industry is quite important to avoid irreversible ecological disaster.

Aquaculture Expansion.

(aquaculturewithoutborders.blog) . The driving force in aquaculture development is multifaceted based on its ultimate goal- either economic gain, foods security and proper nutrition. Players in this field range from commercial producers, rural folk and venture capitalists.

The unprecedented interest in aquaculture has been occasioned by the significant increase in demand for seafood products and paradigm shift in eating habits as far as protein sources are concerned. In recent years many organization have drummed support for better nutrition and to alleviate malnutrition in rural communities while those with huge capital continue the expansive endeavors to meet global demand. In the long run the common denominator is that, all players in aquaculture industry have different targets- economic gain or proper nutrition.

In the economic sense, to match the huge demand for seafood in major importing countries, massive investments have been channeled towards expensive , expansive and super intensive aquaculture systems – ocean or land based. Mariculture development is now taking a center stage as the next frontier because of limited land and land use restrictions especially in EU and North America. If it’s not yet happening, it’s not long before investors start leasing foreign EEZ for aquaculture development.

Marine based aquaculture is gaining momentum because of sustainability challenges in land based system however the future is uncertain because sustainability issues haven’t fully been addressed on open sea systems. On the other hand this industry in quite lucrative however investors are reluctant to venture in because of lack of enough experts, technical know-how and assurance in returns. With all these uncertainties a aquaculture is still expanding at an incredible rate.

Decades ago, aquaculture was confined to only extensive systems but now we have RAS, Intensive pond systems, Super intensive systems , cage culture and so on. Therefore aquaculture has made remarkable strides to get where it is, and still game on.

Africans push for sustainable aquaculture

(thefishsite.com) The projected rapid growth of the aquaculture sector in Africa needs timely interventions to mitigate its potential negative impacts on the continent’s critical aquatic ecosystems, according to leading experts.

Personnel from key national, international and United Nations agencies, who were attending a three-day workshop on Sustainable Inland and Marine Aquaculture in Africa in Nairobi last week, said boosting aquaculture productivity in Africa to address food security and catalyze social and economic development is achievable without compromising environmental health.

Snapshot: Universities in Aquaculture development.

It’s in record that aquaculture is the fastest growing form of animal production. This trend is driven by recent changes in food preference – increased consumption of white meat, diversification of economic activities, increased income and R&D. According to FAO 2018, capture fishery production has been relatively static since the late 1980s so aquaculture’s impressive growth has filled this void.

To ensure that aquaculture economically sound and sustainable, governments and private ventures have channeled huge budgets towards this sector. Some of the key players in aquaculture development are universities which are at the forefront to develop sustainable production systems, do research in fish feeds (nutrition), larval culture, aquaculture economics and genetics.

Just to mention a few of the academic institutions, Auburn university school of fisheries, aquaculture and aquatic sciences research, teaching and extension has trained thousands of aquaculture experts globally. Its International Center for Aquaculture has conducted development activities in more than 100 countries in many regions of the world (sfaas.auburn.edu). Working closely with Auburn University is the Aquafish innovation lab (formerly Aquafish CRSP) of Oregon state university in the college of agricultural sciences. Through USAid funding, this institution has done aquaculture development in 33 countries – Asia, Africa, and Latin America (aquafishcrsp.oregonstate.edu).

Crossing over to Europe, Wageningen university is involved in the whole chain of aquaculture research –breeding, genetics, rearing systems, nutrition… all the way to economic aspects. This university is collaborating with other universities globally. In a more practical perspective, for instance it’s working with business entities such as De Heus (Netherlands based feed supplier with factories in 10 countries) in aquaculture research and development in Vietnam. Note that Vietnam is now ranked 4th in global aquaculture production.

We cannot fail the mention Ghent University which is the home of Aqua Ugent-one of world’s leading research partners for sustainable aquaculture (aqua.ugent.be). It’s in this university that we have the laboratory of aquaculture & artemia reference center (ARC) – renown in culture of fish and shellfish larvae. ARC has footprints in Europe, Asia (especially Vietnam) Latin America and Africa.  Its spin-of company “Artemia Systems NV” (established in 1983) was taken over by INVE Aquaculture NV in 1991. INVE is now a leading aquaculture feed company with branches in many countries in Europe, Asia & the Americas. (aquaculture.ugent.be)

Still in Europe, The institute of aquaculture at the University of Sterling is a world-class aquaculture research, technological innovation and consultancy institution (stir.ac.uk). This institute has links in more than 50 countries and does research in sustainable aquaculture geared towards, aquatic food security…

Therefore it’s clear that universities have channeled substantial about of resources towards aquaculture development globally.  We’d be talking about other universities at a later date.
