Into the world of Illegal fishing: what can be done about it

Think about the variety and quantity of food that is available to you every day, just waiting to be ordered, bought, or selected to become part of your favorite meal. Now imagine a world where this variety is no more, where the different types of fish available at the local market have been reduced to a select few. This scenario is not as far from reality as it might seem, in that illegal fishing in the Southern Ocean has ravaged the populations of many fish species. This is a story on illegal fishing and how international policy works to combat the devastation that it has on fish populations and how different people can relate to this issue through their perspectives.

Lindsay Aylesworth, a PhD student in zoology from Miami, Florida researched the effects of illegal fishing of a species known as the Patagonian Toothfish in the waters near Antarctica and how an international organization known as the CCAMLR has responded to regulate the fishing in the area in order to sustain the fish populations that may be in peril. The following interview explores two perspectives, one where Lindsay talks about how this organization works and another where a local fisherman talks about his experience with fishing policy and regulation on his own boat:

Through both of these insights, there seems to be a very strict code of regulation that is followed in at least the Canadian fisheries, and it seems like the involvement of these regulators on the boats truly deters, if not prevents illegal activity.

Now it may seem like there are some big players involved in regulating the oceans, but that does not give everyone else an excuse to ignore the case of the Patagonian Toothfish because the market for fish boils down to the consumer. Thus if the public is not aware of this issue then, then vibrant and diverse selections like what is shown below may not exist in the future.

In effect, it is crucial to look at the big picture to examine how the CCAMLR can provide more credibility in the data that it collects and how consumers can help build awareness, as Lindsay points out:

It is only through collective effort and awareness that illegal fishing can be reduced, and the easy part, as stated by Lindsay, is as simple as asking where the food is coming from at the dinner table. Time will tell if these efforts by consumers and governments pay off and prevent the decimation of fish populations all over the world.

Spend Less Time, Burn More Calories!

Many people go on their daily jogs to stay in shape or to get in better shape over time, these long jogs are popular because they are relaxing and enjoyable, while they still elicit a nice sweat at the end to make it all feel worth while. However, for those who are intent on burning extra fat during their busy schedules, there is a more efficient and rewarding routine, one that could take only 15 minutes out of the day, known as High Intensity Interval Training (HIIT). Here is an example of a routine:

Example HIIT for 12 minutes (http://ittybitsofbalance.com)

Interval training entails maximum effort for a short duration, and a longer rest period, while repeating again and again. This method brings out a big response from the body because it is so demanding, and that is why this form of exercise is also great for many high intensity sports such as basketball and football. These facts are summarized in the following video:

About HIIT benefits for sports (by BodyPerformanceTV, https://www.youtube.com/watch?v=ulPnlyWURz4&playnext=1&list=PLB33940F0924CA1F8&feature=results_video)

One of the other major effects of HIIT that trumps long and less-intense ‘cardio’ sessions is the fact the your body still burns calories well throughout the day after the exercise is complete! Also, keep in mind that interval training will take less than half of the time, and will burn more calories in-session if done with 100% effort. The following are the results of a small study that examined the overall effects of HIIT vs regular cardio:

Results of 2 groups tested: HIIT vs regular cardio, fat loss compared in pounds. (musclecoach.com, http://cdn.shopify.com/s/files/1/0069/0032/files/high-intensity-interval-training-workouts_grande.jpg?105628)

Thus when solely considering the most effective and efficient means to losing fat through cardio-like activity, interval training is truly superior to less-intense jogs in that it takes less than half an hour to get a workout in and it burns many more calories, throughout the day. So if time is not on your side, don’t let a busy schedule deter you from your goals and adopt a workout routine that can involve interval training.

Processors for Gaming: Old vs. New

Nobody enjoys lag and poor graphics while playing games on their computers because of a slow Central Processing Unit (CPU); so when it comes to choosing the right parts to do the job, don’t rely on advertising and pushy sales people to give you an honest choice that will give give you the best bang for your buck; after all, newer technology does not always out-do the older.

Intel’s Core i5 and Core i7 are the two of the top CPU’s on the market today, and many pre-built gaming computers will boast having the newer (and more expensive) Core i7 with ‘Hyper-threading technology.’ Take a look at the following sales points for the i7:

That all seems cool, but this processor is valued around $100 or even more compared to Core i5 processors, as shown below:

i5 vs i7

i5 price vs i7 in different models, i5 is much cheaper (bottom of table) despite similar specifications (Tomshardware)

So why are the i7’s worth so much more than the i5’s? The major difference that i7’s use what is called ‘hyper-threading.’ This basically means that the CPU can handle multitasking much more efficiently.

When looking solely at gaming capability however, the i7 is overkill price wise to the i5 and completely necessary because most games today do not utilize hyper-threading in the first place. That said, actual game benchmarks tell the rest of the story when comparing the two CPU’s and their relative performance (in frames per second) for the new game called Skyrim:

i5 vs i7 skyrim benchmark

benchmarks for i5 and i7 CPU’s in game ‘Skyrim’ in frames per second (higher value means smoother video output that you see). Both are relatively equal. (notebookcheck.net)

As shown above, the top i7 model produces a maximum of only 2.2 frames more per second than the oldest i5 model. This test shows that the cheaper i5 CPU’s (without hyper-threading) are on par with the newest and most expensive generation in the i7 CPU’s. The sum of these arguments is given below,

applications of i5 and i7, which one is better for different tasks. (custompcreview)

As mentioned above, for gaming, the i5 is truly the way to go when gaming and basic applications are that majority of tasks to be done by the computer as opposed to the newer and more advanced i7 processors. This is interesting considering that in this day and age, ‘newer’ is often synonymous with ‘better’ (especially with computer science and technology advances).

Most comparison tests will render similar results to the above example, and that takes into account the fact that even the most demanding games like Skyrim do not take advantage of the hyper-threading that i7 processors boast. Thus the i5 generation of CPU’s are perfect for basic tasks and gaming and will save at least $100 if bought instead of an i7. That $100 or more that is saved by purchasing an i5 instead of i7 can go towards purchasing a nice monitor to play your games on.

Creatine: Quantity Over Quality

          Creatine has become a very popular and sports supplement today and is used by many athletes to improve their performance in high-intensity sports because its energy-inducing effects are undeniable, but the supplementation is highly dependent on a very high volume of ingestion to actually render these effects.  As a result, popular supplement companies tend to include this name in products to raise the price, while in reality, many of them only include minimal amounts into the actual product.

Creatine is a molecule that is produced in the body that aids in providing energy for the cells through the mechanism for ATP synthesis by phosphorylation. Creatines’ role is carried out by a special kinase. This function is depicted by the following link:

By supplementing diet with extra creatine, the idea is that there will be higher abundance of fuel for ATP synthesis which in turn will project a higher performance in high-energy demanding actions, Dr. Rutledge discusses these effects to a broad audience in the following interview:

Creatine discussion on nutrition (Dr. Rutledge)

The downside to this supplementation however comes down to the practice of how it must be taken. The most basic and trusted form of the compound is called creatine monohydrate. This compound readily forms an acidic bi-product called creatinine under the acidic conditions of the stomach. Thus only a fraction of the original desired molecule is actually absorbed. In effect, the only way to actually saturate the muscles with creatine is to ingest about 20g per day for about a week to compensate the loss to formation of the bi product. The acidic state of the stomach and its effect on creatine can be seen from the following illustration:

Here we see that over time, ingested creatine monohydrate will indeed degrade, which in turn hinders its usefulness.

The dirty play by popular pre-workout brands is that they exploit the name of creatine to jack up prices, while most pre-workout products only contain 5-10g, hardly an effective dose for a single workout. One such example is given by ‘SuperPump Max’ by Gaspari Nutrition, where creatine is noted in their ‘propriety blend’:

SuperPump label

SuperPump label (~11.3 grams of creatine) (http://www.nutritionwarehouse.com.au/upload/image/supering%281%29.jpg)
Gaspari Nutrition

This product is sold at about $50 for around 600g, which is quite expensive considering such a large serving size(16g). If the word on the street is that creatine should be loaded at 20g for about a week to reach effective levels, then what use is the small portion included in SuperPump other than to boost marketing and price?

Since this effective supplement may only be effective in high doses, the quality of products sold by major brands is very questionable when high prices are compared to the actual product. Thus the low potency of creatine monohydrate makes this supplement a case of pure quantity in that the desired effects of the product can only be achieved through a high intake over time. Clearly, is impossible to achieve through many pre-workout supplements that boast creatine in their labels, but fail to include adequate amounts.
