Extreme Weather Hits Tilapia Output by Paul Icamina (March 28, 2017)

Tilapia farming is in for a dire future – unless something is done about it.

And that’s what farmers, weather scientists and agriculturists are doing, preparing for what they see as the inevitable impact of a changing climate.

“The major tilapia producing regions in the Philippines are now experiencing significant impacts from the progressing negative effects of climate change,” according to a report prepared by the Bureau of Fisheries and Aquatic Resources (BFAR), Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) and the United Nations Food and Agriculture Organization (FAO).

“Tilapia pond-aquaculture farmers are alarmed at the recurrent decline in farm productivity; mass mortality and fish kill brought about by prolonged dry season; increasing air and water temperatures; critical dry spell and drought; frequency of strong thunderstorms; and heavy rainfalls which induce flooding and overflows of aquaculture farms,” the report stated.

Citing the key findings of a Special Report on Emission Scenarios by the Intergovernmental Panel on Climate Change, the report projects that seasonal rainfall will generally increase and that temperature warming will occur for all seasons. “Extreme events are likely to increase in the period 2011-2040,” it said.

Global climate change affects aquaculture, bringing tropical storms, typhoons, cyclones, flooding, strong winds, tornados and extreme temperatures that impact off-shore and inland fish farms. 

Climate change induces rise in temperature, changes in rainfall patterns and frequent typhoons with extreme flooding, together with change in wind direction that alters the characteristics of near-shore fish habitats, ocean circulation pattern, coral reef production and fish migration pattern.

It will be greatly felt in coastal areas through rising sea level which would flood low-lying wet and dry land areas, erode shorelines, worsen storm flooding, increase salinity of estuaries and threaten freshwater aquifer. Areas devoted to fishery will decrease in size while important fish species may move to other areas making it less available to fishers.

Tilapia production from freshwater and brackishwater ponds accounted for 716.4 tons out of the country’s fisheries output of 261,210.41 tons in 2015. Most tilapia pond operators follow semi-intensive system in producing marketable size tilapia for the local market.                

With inputs from PAGASA and FAO, BFAR has issued an Aquaculture Bulletin that covers the dynamics between tilapia farming in relation to the impact of weather systems on day-to-day pond management and operations. It is based partly on a participatory workshop among farmers from major pond-based tilapia farming provinces, aquaculture scientists and weather and climate experts.

 It complements tilapia technology guides and manuals, most of which assume conducive weather or climatic conditions that are not often the case.  

 The information promotes agricultural adaptation to climate change through climate smart farming and fisheries, and reducing disaster risk through the use of weather and climate information, said Dr. Vicente B. Malano, PAGASA administrator.

One weather system, for example, that immediately impacts on aquatic habitat is the northeast monsoon (Hanging Amihan). Cold winds blowing from the northeast direction cause cloud development and rainfall at the eastern section of the country; this normally occurs from November to February.

Amihan causes widespread cloudiness and heavy rainfall, low air temperature, flooding and cold wind while rain may reduce water temperature (less than 24 degrees Celsius) that is stressful to tilapia.

Fish Recipes for Lent

Fish Recipes for Lent

You don’t need to be Catholic/Christian to enjoy a tasty meal of fish on Friday! Think of Fish Friday as an alternative or partner to Meatless Monday. Fish offers numerous nutritional benefits and many nutritionists recommend eating fish at least once a week. So why not on Friday, when you have the time to cook fish and want to enjoy a delicious meal after a long work week?

What exactly about fish makes it so nutritious? Fish is one of the best sources of omega 3 fatty acids, which reduce inflammation, improve recovery, and boost athletic performance. Fish provides a high source of protein, which additionally assists in the recovery process.

While you could receive the benefits of omega 3 fatty acids from fish oil pills, as with many nutrients the actual source is preferable to the supplement. No supplement can provide the rich yet light taste of a bright pink salmon filet or the mouth-watering flavor of a fresh piece of blackened cod on a fish taco.

Many people avoid cooking fish based on the misconception that fish is messy and difficult to prepare. In my experience, quite the opposite is true. Fish requires a short cooking time and can be poached, baked, pan fried, or seared, meaning that there’s a method for preparing fish that will fit your culinary style.

Fish Fridays can pose a challenge in terms of meal planning, finding recipes, and knowing which type of fish to select from the market. So, as Lent begins next week, this week I’m sharing a round up of Lenten fish recipes!

These fish recipes contain no other meats (since bacon-wrapped scallops may be delicious but don’t meet the meat-free requirements of Fish Friday). With this many options, you can eat fish for lunch and dinner each Friday in Lent without ever repeating a recipe. Pair your fish with whole grains or potatoes and some roasted vegetables or a side salad and you have a nutritious and satisfying meal.

Why Do People Eat Fish During Lent?

Why Do People Eat Fish During Lent?

Lent, a religious tradition observed during the 40 days before Easter, is an important period of the year for many Christians, especially Catholics. It’s a time to pay respect to Jesus’ sacrifices, suffering, life and death, through both increased mindfulness, prayer and adherence to certain practices.

For 57% of those who observe Lent, that includes fasting—but not in the formal sense of the word. A religious fast is a strict form of diet rather than abstaining from eating any food at all. While some foods and meals are cut out, there are many other things practitioners can enjoy, such as fish. Here’s a breakdown of why many Christians eat fish during the Lenten season.

It Dates Back to Roman Times

The Lenten diet consists of the food an average person could get themselves during the Roman period—namely, fish and vegetables. Essentially, meat is the only food that’s omitted from this diet, since it was considered a food for the upper class and Lent is a time to eat as the poor would. This is also a time to recognize that Jesus sacrificed himself and therefore, observers pay respect by abstaining from the fleshy meat of beast and bird on Ash Wednesday and all Fridays during Lent.

Fish is Affordable

In theory, anyone can catch a fish and feed themselves and their family. Rich or poor, in both Roman times and today, anyone could simply walk to a river or lake and find themselves with a protein-rich dinner. Fishing doesn’t require complex equipment and, at the time, was a free mealtime solution. In grocery stores now, seafood is often priced higher than some meats (though fish like Tilapia at Costco can be very reasonable), but that’s due to the commercialization of the industry. Seafood was not considered a luxury in biblical times and therefore, is an acceptable alternative to meat during Lent.

Fish is Not Considered Meat

Another reason fish is consumed during Lent? Fish has no “meat taste.” Jesus’ flesh was that of a warm-blooded mammal and fish was and is a cold-blooded animal. While this is a scientific difference and not a biblical one, the blood of the animal is the largest difference between the proteins besides the taste. In biblical records, the flesh of fish is separated from the flesh of man, beast and bird. This verse is used as the bedrock for the allowance of fish during Lent.

Fish has been a staple in Christian diets for a very long time. Moreover, it’s a core part of Lent to include it in meals during the fast. While explanations might differ as to why fish is allowed during Lent, it has always been and will likely remain an important part of this religious period.

Know your FISH - Tuna

Tunas are one of the most consumed fish species. There are 8 species of tuna. All species of tuna are nomadic, which means that they do not spend their entire life on a single place. Instead, they often change their location. Tunas are usually located in temperate and subtropical waters of Atlantic Ocean, Mediterranean and Black seas. Tunas are over-fished in different parts of the world, especially in Japan and Australia. As a result, number of tunas decreased for over 90% percent since the beginning of 20th century. Although tunas are listed as endangered species, fishermen around the world hunt them persistently.

Interesting Tuna Facts:

Tuna is a large fish. It can reach length of 6.5 feet and weight of up to 550 pounds.

Largest (ever recorded) specimen of tuna was 21 feet long, weighing 1600 pounds.

Color of the body provides excellent camouflage in the water. Dorsal (back) side of tuna's body is dark blue and it blends with the ocean floor when observed from the air. Belly of tuna is silver-white and it blends with the surface of the ocean when observed from below.

Despite their large size, tunas are very fast swimmers. They can reach the speed between 44 and 62 miles per hour.

Tuna is able to change the position of its dorsal and pectoral fins to reduce drag and accelerate the swimming speed.

Tuna can swim near the surface or can dive to the depth of 3000 feet while it searches for food.

Tuna is a carnivore. It feeds on different types of fish (mackerel, herring, hake…), squids and crustaceans.

Unlike other fish, tuna is able to increase and maintain the body temperature few degrees above the temperature of surrounding water. Because of this feature, tuna can be classified as "warm-blooded" animal.

Tuna has unique network of small arteries and veins near the muscles called "rete mirabile" which facilitates warming of the blood. Warmed blood is essential for fast and strong swimming.

Tuna breathes oxygen from the water and because of that it needs to swim constantly.

Tunas can travel large distances in a short period of time. It can pass across entire Atlantic in 30 days by traveling 16 miles per hours

Besides humans, natural predators of tunas are orcas and sharks.

Mating season of tunas depends on their geographic location. Tunas in Gulf of Mexico mate from middle of April to middle of June. In Adriatic and Mediterranean Sea, mating takes place from June to August.

During the spawning, one female can release 30 million eggs. Only 2 of those 30 millions will survive until the adulthood. Remaining eggs will be eaten by other marine creatures.

Average life span of tuna is between 15 and 30 years in the wild. Small percent of tuna managed to survive until this period.

Brief History of Milkfish aquaculture and market in the Philippines

Brief History of Milkfish aquaculture and market in the Philippines

The milkfish is an important seafood in Southeast Asia and some Pacific Islands. Because milkfish is notorious for being much bonier than other food fish, deboned milkfish, called "boneless bangus" in the Philippines, has become popular in stores and markets.

Milkfish aquaculture first occurred around 800 years ago in the Philippines and spread in Indonesia, Taiwan and into the Pacific. Traditional milkfish aquaculture relied upon restocking ponds by collecting wild fry. This led to a wide range of variability in quality and quantity between seasons and regions. In the late seventies, farmers first successfully spawned breeding fish. However, they were hard to obtain and produced unreliable egg viability. In 1980 the first spontaneously spawning happened in sea cages. These eggs were found to be sufficient to generate a constant supply for farms.

Milkfish processing takes two forms. Traditional ways include smoking, drying and fermenting. Bottling, canning and freezing are of recent origin. There has been a steady increase in demand since 1950. In 2005, 595,000 tonnes was harvested worth USD $616 million.
There is an increasing trend toward value-added products. In recent years the possibility of using milkfish juveniles as bait for tuna long lining has started to be investigated, opening up new markets for fry hatcheries.

Eat fish, live longer by Peter Lavelle (published 14/07/2005)

Eat fish, live longer by Peter Lavelle (published 14/07/2005)

One or two servings of fish a week will reduce your chances of getting heart disease, because it's rich in omega-3 fatty acids.

Next time you're passing your local fish market, pull up, get out of the car, part with some money and take home some fish. You'll live longer than those people who've driven on by without stopping.

That's the conclusion of an increasing number of studies showing that eating fish regularly lessens your chance of getting heart disease, and might help other medical conditions too.

Not only is fish is high in protein and low in fat, it contains a type of polyunsaturated - or 'good' - fat, called omega-3 fatty acids. There are two main ones in fish: EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). They're thought to act as natural anti-inflammatory agents.

Seven Days Fish Diet Plan

Holiday season is almost over. Some of us forget our DIET routine, because of the sumptuous meals served over our buffet tables. Here's a quick diet program to lose the weight gain these past holidays.

Fish is one of the excellent natural sources of proteins and essential amino acids. Fish diet is considered as one of the ideal ways to reduce weight. Fish diet lasts for one week by following the same diet plan throughout the week which can shed 5.7 kilograms within seven days.

Fish Diet Plan

For breakfast:
Have 1 whole boiled egg with apple and green tea

For lunch or second breakfast:
Eat cooked lean fish of 200 grams plus cucumber and one glass of mineral carbonate water

For dinner:
Eat cooked lean fish of 200 grams again, 150 grams of cottage cheese which is fat-free, lettuce and green tea

Fish Diet to Lose Weight
Fish diet seems to be the ideal diet for weight lose because of its high protein content and amino-3 fatty acids. But the big question remains whether using fish diet for weight loss is healthy one or not? So here are few precaution and points to remember during fish diet.

You need to choose a good variety of fish. Consuming the exact same meal for continuous day may be quite difficult, so try to prepare in different way and add more variety.
Canned tuna seems to be the best because of its high content of protein, omega-3 fatty acids and low in calories, you can add other fresh fish to help you stay on diet.
Instead of going for fried dish go for baked and grilled fish


Warning and Precautions
This diet is not recommended for pregnant women because there is a high chance of getting mercury contamination which is injurious to the fetus
Avoid eating excess carp and catfish because these fish eat anything and accumulate pollutants and lots of dirt in their flesh. Limited eating may not harm much, but these fish should not be kept as the mainstay in your diet.
