Marine fisheries are distinguished into two types. These are Inshore and Offshore fisheries. Inshore fisheries  – Shore line to 5 nautical miles in northern areas   and 10 nautical   miles in the southern area Department of Fishery “DOF” allowed to fishing vessels  less than 30 feet’s (12 HP) Offshore fisheries  – Outer limit of Inshore fishing zone to EEZ, DOF  allowed to  fishing vessels more than 30 feet’s (above 12 HP).

El cultivo de tilapia, Oreochromis sp. en Peru – in Spanish

Credit: David Mendoza Ramirez (Peru)

El cultivo se desarrolla en selva alta y en la costa norte aprovechando las represas y recientemente en jaulas, existe tecnología disponible. El nivel de producción es de mayor escala (más de 50 TM/año) y menor escala (2 a 50 TM/año), el principal mercado es el nacional y en una escaza proporción el de exportación. Su desventaja es la informalidad y la limitada competitividad para un acceso estable al mercado de exportación.

Reef stonefish, Synanceia verrucosa (introduction, distribution, feeding habits, reproduction, commercial value)- video

This video was taken during June 2012 at the Sea World, California, USA

Review: Abdel Rahman El Gamal (Founder of the website and video channel)

Introduction: The stonefish, Synanceia verrucosa which belongs to the family Synanceiidae is a fish species, which is widely known as the reef stonefish, rockfish or “dornorn”. The average length of most stonefish is about 30-40 centimeters although longer specimens have been reported.

Distribution and habitats: The Reef Stonefish is widely distributed and known to be found throughout tropical, marine waters of the Pacific and Indian oceans. The main habitat for stonefish is coral reefs where they live on reef bottoms. They are also found under rocks or ledges and are also found buried dormant in the mud or sand using their pectoral fins.

Feeding habits: Stonefish eats mostly small fish, shrimp and other crustaceans. This species is patient hunter as it usually waits motionless for prey to swim past, and then strikes with incredible speed. The mouth cavity of stonefish expands creating a vacuum allowing them to swallow small prey. It is believed that if enough food is present, this fish demonstrates its sluggish nature and will stay in the same general area of the reef for very long periods. Hunting preys is greatly enhanced by the outstanding ability of stonefish to camouflaging themselves and giving the appearance of a rock and hence fool their prey and catch them unaware.

Reproduction: A stonefish female may produce about a million eggs. Because of potential predation by other fishes, only a small number survive till maturity.

Commercial value of stonefish: The primary commercial merit of stonefish is as an aquarium fish. However, stonefish are food fish in some countries like Hong Kong and the Philippines. It is also consumed in Japan as sashimi.

Note: One may not be able to identify the fish among the surrounding rocks. Please visit the second post on the same species where you will be able to see the excellent camouflaged fish when moving and leaving the surrounding rocks.

Reef stonefish, Synanceia verrucosa (camouflage, predators, Poisonous venom) – video

This video was taken during June 2012 at the Sea World, California (USA)

Color and camouflage: The common color of stonefish is the mottled greenish to mostly dark brown color. They may have patches of yellow, orange or red color. This type of coloration enhances their ability to camouflage themselves among the rocks or many of the tropical reefs. Stonefish are extremely well camouflaged, looking like stones, rocks or lumps of coral. It may worth mentioning that the “stonefish” derives from their ability to camouflage itself similar to the color of a stone. Because their excellent camouflage and ability to blend with corals, they are easily overlooked by swimmers and divers.

Stonefish predators: Predators of the Reef Stonefish include sharks (tigers and white sharks) and rays.

Poisonous venom: The Reef Stonefish is known to be the most venomous fish in the world. Its dorsal fin has thirteen stout 13 spines that release extremely poisonous venom from two sacs attached to each spine. Its venom causes severe pain with possible shock, paralysis, and tissue death and it is believed to have killed many Pacific and Indian Ocean islanders especially if immediate medical attention was not available. The risk of venom toxicity increases for persons under the age of seven as well as for very old persons. The development and use of the antivenom has reduced the fatality due to the venom. Stonefish antivenom is the second-most administered in Australia.

Because of the excellent camouflage of stonefish, swimmers and divers may not notice them, and may inadvertently step on them, triggering a sting. When the stonefish is disturbed, it may inject an amount of venom proportional to the amount of pressure applied to it. Most stonefish stings occur when stepped on.

All water used in aquaculture is the same water used in plant production. The underground water is the only water resource used in both systems (plants and fish). Water depth ranges from 70-100 m. Wells are licensed by Palestinian Water Authority who also determines the quantity of water discharges based on agriculture acreages.

Initial farming of Indian white prawn, Penaeus Indicus in Egypt

Photo credit: Adel Mansour and Hussien Mansour (Egypt)                   Review: Abdel Rahman El Gamal

Even though the Initial attempts of shrimp farming in Egypt goes back to about 10 years back, the productivity per unit area was never satisfactory due to variety of reasons. The farmed species is considered among those reasons. For years, green tiger shrimp, Penaeus semisulcatus has been tried but with modest productivity. The request to import whiteleg shrimp, Liptopenaeus vannamei was rejected by fishery authority according to fishery law. Instead, the Indian white prawn was tried starting several years ago with better outcomes. The photos show the harvest of the Indian white prawn harvested from a shrimp farm located along Port Said-Damietta road.
