New laws put in place in Tanzania to punish dynamite fishermen
Tanzanian authorities are in the process of enacting laws that will mete out heavy penalties for fishermen engaged in dynamite fishing which is now rampant in the east African nation, an official said last week. Fatma Sobo, the Assistant Director of Fisheries Resource Development, said dynamite fishing in Tanzania’s Indian Ocean Coastal line was out of control.
“Controlling dynamite fishing is difficult because of the involvement of politicians,” Sobo told a two-day workshop for key actors in the marine fisheries sector in Tanzania gathered to identify challenges facing the tuna fishery sub-sector and seek common solutions.
She said the government has formed a task force with members the Tanzania People’s Defence Forces (TPDF), the Ministry of Home Affairs and the government’s environment department to find out how the fishing malpractice could be eliminated.
Sobo said that in 1997/98 dynamite fishing in Tanzania was almost eliminated after the involvement of TPDF. Mwanaidi Mlolwa, a senior official with the Ministry of Livestock and Fisheries Development, said the process to review fisheries laws was intended to make dynamite fishing a treasonable offence.
“The current laws are not deterrent enough,” she said. According to the Fisheries Act of 2003, any person who uses explosives to kill fish or destroy aquatic flora shall be liable to imprisonment for a term no less than five years and not exceeding 10 years.
In a recent world map of the Global Reefs at Risk initiative, Tanzania is the only African country where dynamite fishing occurs – a practise that destroys coral reefs.
A survey conducted in Tanga Region in the 1990s showed that 10 per cent of coral reefs were damaged beyond recovery, while 70 percent had significant damage but could recover if protected.

Book Review: Shells of the World
Shells of the World: A Natural History by M.G. Harasewych
Shells of the world is a guide to the world of marine, shelled molluscs. And what a varied and interesting world it is. Some of my favourite things to find on a dive are detailed in this book, including disco clams (or Electric File Clams as they are correctly names), the cephalopods, giant clams and sea hares. There are also many on my wish list, top of which is the Nautilus.
Each chapter provides a detailed description of the species, along with beautiful images. You can dive deeper and discover where they live, both with global distribution and the habitat they prefer. Learn about their diet, reproduction and diversity.
Having dipped in and out of this lovely book over the past few weeks, it has inspired me to learn more about this group of animals that we see on most divers, wherever we are in the world. Some of the shells are incredibly intricate and beautiful. I have always agreed with never collecting, or touching, marine life. The description of a certain set of cone shells should be a warning to those that are happy to pick up marine life! One of the cone shells has a local name called the cigarette snail. Why? Because once the venom is in your system from this animal, you only have time to smoke one cigarette before the affects of the venom are fatal!
What the publisher says:
Mollusks are invertebrate animals with a remarkable natural history and a rich fossil record, and their shells are prized for their breathtaking variety and exquisite beauty. Shells of the World provides a wide-ranging look at the incredible diversity of marine mollusks. An informative introduction outlines the lineages covered, followed by a directory section, split into classes, that profiles a broad selection of different taxa to give a sense of their sheer numbers and variety.
- Features hundreds of beautiful color photos, depicting both the live animals and their shells
- Discusses mollusk evolution, anatomy, life cycles, behavior, and ecology
- Describes unique characteristics, distribution, habitat, and size
- Provides valuable insights into the conservation of the world’s marine mollusks
- Ideal for malacologists and shell collectors everywhere
