Under the blue-green
Isinglass of the sea
I hear the melody
black Jewelfish sing
as sleek males hum
their love songs
the sonic muscle
a mating organ Bach
might have played
in the 17th Century if he
had lived in the Pacific reefs
off Santa Catalina, which,
on a clear day Bill Ackerman
in his youth could see
from Laguna, but the males
have no interest except
in the bubble nests where
fertilized eggs will pulse
in the currents, a kind
of rhythmic tempo Johann
Sebastian might gather
in his arms as rainbow-hued
Paradise Fish and Barbs
and Blue Bettas and Deltas
swim through his fingers
on the way to spawn,
a small cantata starting
or a concerto which
by the end of the day
as westerly trade winds
sweep in will swell to a
choral masterpiece even
the sun might notice as it
crescendos gloriously into
the flaming horizon
--Miguel de O

my dad swimming with tropical fish out on the reef. (I had just climbed out of the water.) the fish were everywhere! angelfish, parrotfish, jewelfish, yellowtail, and many others. they were close enough to pet, but always managed to stay just beyond my fingers.
Many varieties of fish are found in the Nile system. Notable among those found in the lower Nile system are the Nile perch (which may attain a weight of more than 175 pounds), the bolti (a species of Tilapia), the barbel, several species of catfish, the elephant-snout fish, and the tigerfish, or water leopard.
However, prospects for Nile fishermen are not promising. Many schools of fish that fed in the waters of the Nile in Egypt during the flood season have been reduced or have disappeared since the construction of the Aswan High Dam. Most of the species of the Nile fish were migrants, and the dam has prevented many from migrating to Lake Nasser. The diminution in the number of anchovies in the eastern Mediterranean has also been attributed to the serious reduction in the outflow of waterborne nutrients due to the dam.
Almost half of the Nile fish depicted in ancient reliefs are now extinct from Egyptian waters. Researchers comparing historic fish collection records estimate that as many as 35 of these fish species, including the elephant fish, Nile jewel cichlid, and African bony tongue, disappeared from the lower reaches of the Nile in the last 40 years. Dozens more are listed as threatened or endangered.
Justin Grubich, assistant professor of biology at the American University in Cairo, says Nile river fisheries suffered a catastrophic decline following the construction of the Aswan High Dam in the 1960s. The dam acts as a barrier, impeding the reproductive cycle and migratory routes of many fish species, and preventing millions of tonnes of silt and organic matter from reaching the lower Nile.
“The High Dam was built to control the flood season so as to have more consistent agriculture,” Grubich explains. “The dam helps regulate water better, but downstream there is no replenishment of soil and nutrients (to support aquatic life).”
The impact is felt over 1,200 kilometres downstream. Without sedimentation, the Nile delta is receding, in some areas by several metres a year.
The coastal erosion has allowed the sea to advance into a series of shallow lakes at the mouth of the Nile, killing freshwater species unable to tolerate the higher salinity. It has also allowed predatory marine fish to invade spawning and nursery areas, devastating fish stocks.
Research conducted in the 1970s found that aquatic biodiversity in the four Nile-fed Delta lakes in Egypt had decreased significantly. Surveys by the National Institute of Oceanography and Fisheries (NIOF) identified 34 species of fish in Lake Manzala, compared to more than 50 recorded half a century earlier. Similar patterns were found in nearby Lake Burullus, which had become exceedingly brackish.
And polluted. Over 4.5 million tonnes of industrial effluent, including 50,000 tonnes of hazardous contaminants, is poured into the lower Nile each year, according to the environment ministry. The pollution, which also includes agricultural runoff and untreated sewage, poisons aquatic life in the river and concentrates in the lakes at its mouth.
Juvenile fish are extremely susceptible to pollution, which can kill them directly, “or create a large volume of decaying organic matter that uses up all the dissolved oxygen that fish need to survive,” says Osman El-Rayis, professor of chemistry at Alexandria University.
Lethal levels of water toxins may have already extirpated the jewelfish, which once flourished in the Nile delta and northern lakes. Fishermen say the plump, bottom-scouring moon fish is now rarely seen in the river. And the once ubiquitous Nile minnow, which moved in large schools in the shallows, is now restricted to a few locations near Aswan.

Anthers are small, brightly-colored marine fishes (subfamily Anthiinae of the family Serranidae) that have elongated bodies, inhabit coral reefs, often occur in large schools, and include several popular aquarium fishes.
Members of the subfamily Anthiinae (Fancy Basses) are known by many common names around the world. Labels include: wreckfish, reeffish, goldies, seaperch, swallowtails, fancy basslets, and jewelfish - just to name… more than a few. era.
Anthias and most wrasses are protogynous hermaphrodites. This means they are born female but if a dominant male perishes, the largest female of the group will often change into a male to take its place. On the other hand, clown anemonefish are protandrous hermaphrodites. This means that they mature as males and the largest one will change into a female when the resident female dies.

While I sat watching I saw several different southern water snakes (Nerodia fasciata) successfully catch and eat fish (in each case African jewelfish) in the shallow water. When they tried to swallow the fish tail-first it could take several minutes. Tamiami Trail E, Everglades National Park / Big Cypress National Preserve, Florida

This airmail stamp (= Scott Catalogue # C6) was issued on 15 November 1965 by Ajman, which is located in the eastern Arabian Peninsula. Ajman is both a city and a country (also referred to as an emirate, a sheikdom, a Trucial State, and a confederation). In modern times, it is part of the "U.A.E." = the United Arab Emirates. Ajman formerly issued many postage stamps in the 1960s and 1970s, as did other Trucial States in the region. The stamps were created specifically to be sold to non-domestic stamp collectors to raise money ("revenue") for each country. They were not even printed in the countries that bear their names. As such, they are not really postage stamps - they were not sold from Ajman post offices and not used on their mail. Many depict subjects or topics completely non-related to the home country. Serious stamp collectors collectively call these non-stamps "Dunes" or "Trucials" and consider them worthless. There's reportedly been renewed interest in Trucial stamps in recent years.
