Restocking the Seas around Bahrain through Fish Farming

The marine waters around Bahrain have been showing a decline in fish stock for several decades. But in the first decade of this millennium, restocking has become a routine practice endorsed by the former Public Commission for the Protection of Marine Resources, Environment and Wildlife (now the Supreme Council for the Environment). In recent years, the fishing industry in the Kingdom of Bahrain is starting to really look up with the restocking of the waters from farmed fish. Requirements of a Fish Farm Fish farming means growing fish in fixed enclosures (tanks, ponds or cages) exposed to the natural climatic conditions … Continue reading →

Over the last decade we have become increasingly alarmed at the amount of plastic in our oceans. More than 8 Million tons of it ends up out oceans every year and if we continue to pollute at this rate, there will be more trash than fish by the year 2050. By the way, there are 3.5 Trillion fishes in the ocean now. Where does all this waste come from? After analyzing waste in rivers and surrounding landscape, researchers found that most plastic waste comes from rivers; and 90% of this waste comes from only 10 river systems. One of them, … Continue reading →

CO2-Caused Ocean Acidification – Causes and Consequences

“The CO2 problem” has traditionally been understood as the fact that excessive CO2 produces global warming. But near the end of the 20th century, scientists started talking about a second CO2 problem, “ocean acidification”. Ocean acidification results from the fact that about 30 percent of our CO2 emissions have been absorbed by the ocean. This absorption keeps down the warming of the atmosphere that would otherwise be produced by these emissions. Ocean acidification involves the ocean’s pH, changes in which make the water become either more alkaline or more acidic. Tests have shown that “for more than 600,000 years the … Continue reading →

The Menace of Marine Litter

Marine litter, long a neglected topic, has started to garner some attention. Marine litter is composed of a diverse mix of items from various sources and so a one-size fits all solution is unlikely to be effective. Abandoned, lost and discarded fishing gear (ALDFG), shipping wastes, plastic packaging (bottles, caps, bags, etc.) and plastic manufacturing pellets are amongst the most common and persistent items found. Comparing the feasibility and the financial case for recovery versus prevention for each of these groups reveals a worrying gap in our attempts to deal with the problem. Scale of the Problem Abandoned, lost and discarded fishing … Continue reading →
