LA SEMAINE A \u00c9T\u00c9 BIEN REMPLIE<\/strong> <\/span>pour les inspecteurs de p\u00eache \u00e0 bord du Avalon ll, <\/em>and things were just beginning to wind down. The Reef Environmental Education Foundation (REEF) team of 16 volunteer research divers had recorded population estimates for 246 fish species on 26 reef, seagrass, mangrove, and ironshore sites within the benevolent boundaries of Cuba\u2019s Parque Nacional Jardines de la Reina.<\/span><\/p>\n\n\n\n

The Jardines de la Reina (Gardens of the Queen) archipelago, the park\u2019s namesake, was first declared off-limits to commercial fishing by fiat of Fidel Castro in the 1970s and was later granted no-take marine reserve status in 1996 before becoming a national park in 2010. Besides safeguarding the fish-rich waters of the archipelago, the park also protects 840 square miles of prime inshore habitat stretching along 93 miles of the country\u2019s southeastern coastline. Cuba\u2019s multidecade efforts have fashioned one of the largest and oldest no-take coral reef marine reserves in the Western Hemisphere. What a joy to explore a fish haven spared the horror of hooks, spears, traps, longliners, and trawlers \u2014 a place where fish have a chance to mature into large, prolific breeders. It is just the sort of sanctuary the ocean needs more of.<\/p>\n\n\n\n

The story began in 2000, when a few specimens turned up at a tropical-fish-collecting station near Trinidad, Cuba \u2026<\/span><\/p>\n<\/blockquote>\n\n\n\n

Even though we were aware of the park\u2019s abundance and diversity, the moment Anna and I were offered the opportunity to join the Cuba Field Survey, the image of a single little golden fish popped to mind. And oh my, what an interesting bit of fishdom the golden fairy basslet is, considered by fish fanciers far and wide to be the most exciting scientifically described fish from the Caribbean in decades. Most important to us, it is found exclusively on the towering fortress of coral pinnacles skirting the southern coast of Cuba. Without a second thought, we signed on the dotted line.<\/p>\n\n\n\n

Months later, we backrolled into the warm waters of the Gardens of the Queen, made a beeline for a series of overhangs paralleling a sandy 65-foot-deep seafloor, and began peering beneath ledges one after another. We didn\u2019t find any golden fairy basslets, but fairy basslets (Gramma loreto<\/em>(\u00e9galement connu sous le nom de gramme royal), leur esp\u00e8ce s\u0153ur d'apparence similaire et \u00e9troitement apparent\u00e9e, voltige sous les surplombs en plus grand nombre que nous ne l'avions jamais vu.<\/p>\n\n\n\n

We shared what we knew about the new basslet with shipmates that evening. The story began in 2000, when a few specimens turned up at a tropical-fish-collecting station near Trinidad, Cuba, just west of where our boat was moored. When the shipment arrived in Europe, Ari Dejong, proprietor of a major aquarium wholesaler, immediately realized he had a prize \u2014 a beautifully detailed basslet he had never seen or heard of that happened to bear an uncanny resemblance to the royal gramma, a mainstay of the aquarium trade. Sometime later, Dejong shipped three specimens to a pair of prominent fish taxonomists. Even though the new basslet had genetic and morphological markers corresponding to the royal gramma, the taxonomists\u2019 2010 descriptive paper pronounced the basslet a new species: Gramma dejongi<\/em>. Le nouveau poisson pourrait-il \u00eatre un exemple de sp\u00e9ciation r\u00e9cente, comme le propose l'article, ou une variante de couleur locale, comme le mentionnent \u00e9galement les auteurs ? Quoi qu'il en soit, le basset f\u00e9e dor\u00e9 est un petit poisson tr\u00e8s int\u00e9ressant qui repousse les limites de notre compr\u00e9hension de l'\u00e9volution.<\/p>\n\n\n\n

Sharing a boat with accomplished fish finders certainly made our hunt for basslets easier. They had pointed out three of the golden-scaled beauties by the end of the following day\u2019s dives. I must have kneeled next to a shallow undercut for more than 20 minutes while watching my first dream fish of the trip fin-dance around, often upside down, not an arm\u2019s length away. Like the dozen other golden fairy basslets we observed, it was the lone representative of its species living among robust fairy basslet aggregations below 50 feet. Things became even more intriguing when the surveyors began reporting randomly patterned hybrids, offspring of the two sister species.<\/p>\n\n\n\n

After scrutinizing basslets to our hearts\u2019 content, we began concentrating on the discoveries the surveyors constantly chattered about at breakfast, lunch, and dinner. Big fish are an acknowledged staple of the park, and the surveyors had seen a lot. We got a kick out of studying each reef\u2019s squadron of reef sharks \u2014 big, sleek, forever graceful, and a joy to be close to as they escorted us around, politely checking out each of us in hopes of handouts. On top of the reef, black groupers roamed freely, and Nassau groupers always seemed to be nosing around. Jacks reigned above as schools of grunts cloaked the reef flats with color below. Goliath groupers and nurse sharks occasionally stole the show. Among all this rich tapestry lived the more than 200 fish species \u2014 some large, some small \u2014 that the surveyors recorded, including the golden basslet, a terrific addition to everyone\u2019s life list.\u00a0AD<\/p>\n\n\n\n
