A designated area, within a Fisheries Management Area (FMA), where certain specified fish harvesting activities are prohibited.
Industry:Natural environment
A device employing videography used chiefly at night on the NOWRAMP cruises to the Northwestern Hawaiian Islands. TOAD consists of a video camera and lights on a frame designed to be towed just above the substrate. The video is used to certify or ground truth acoustic habitat sensing. Specifically, the TOAD videos show the composition of the bottom in a few locations, such as sand, rubble, sea grass, coral, etc. It allows interpretation of broad area acoustic data by comparing it to the video information.
Industry:Natural environment
An animal phylum containing four classes of flatworms. Three are parasitic (tapeworms, flukes) and one, the Turbellaria, is free-living and contains coral reef inhabiting species.
Industry:Natural environment
An animal phylum synonymous with Ectoprocta that contains approximately 5,000 living species. They are all sessile colonial forms composed of zooids. Zooids are tubular, oval or box-like structures that contain a lophophore, which is a circular or horseshoe-shaped fold of the body wall that encircles the mouth and bears numerous ciliated tentacles. Most species form erect or encrusting colonies. They occur in many different habitats, including coral reefs.
Industry:Natural environment
An animal phylum synonymous with the phylum Bryozoa, the "moss animals".
Industry:Natural environment
A phylum of extremely simple and cryptic marine animals, for which only two species have been described, Trichoplax adhaerens and Treptoplax reptans. These tiny animals were discovered in Europe in the late 1800's living on the glass walls of an aquarium. Since then, most of what has been learned about their biology has come from studying cultures kept in various laboratories around the world. Their bodies are made up of only a few thousand cells of just four types. They also have the smallest amount of DNA measured for any type of animal. They lack tissues, organs and organ systems.They reproduce asexually, but it is not known if they can also reproduce sexually. Practically nothing is known about them in nature. Some scientists believe they emerged early in metazoan evolution, either before or just after the sponges (Porifera). However, recent DNA studies lead others to believe they emerged after the Cnidaria. Of the two species described, Treptoplax reptans has never been seen since its description in 1896, causing some to doubt its existence. However Trichoplax adhaerens has been reported from the Mediterranean and many tropical and subtropical locations around the world. It may be that Trichoplax adhaerens actually consists of more than a single species.

De teelt van aquatische organismen, met inbegrip van vis, weekdieren, schaaldieren en waterplanten met een soort van interventie in het fokken proces ter verbetering van productie, zoals regelmatige kous, voeding, bescherming tegen predatoren, enz. landbouw ook impliceert individuele of collectieve eigendom van de voorraad wordt geteeld.
Industry:Fishing
Groep van soorten beschouwd als samen, vaak omdat ze moeilijk zijn te onderscheiden zonder gedetailleerde onderzoek (zeer vergelijkbaar soorten) of omdat de gegevens voor de afzonderlijke soorten zijn niet beschikbaar (bijvoorbeeld in visstatistieken of commerciële categorieën).
Industry:Fishing
In de evaluatie van de visstand, de waarschijnlijkheid van een vis vistuig (haak, riem, mesh, val) en nadat hij in contact met het door het wordt bewaard. Vaak uitgedrukt als functie van grootte of leeftijd.
Industry:Fishing
De grootste vangst die van de bevolking, op welk niveau van voorraad grootte, meer dan een onbepaalde termijn kan worden gehandhaafd. Het is identiek aan de duurzame opbrengst voor bevolking onder het niveau geven de maximale duurzame opbrengst (MSY), en gelijk is aan de MDO voor de bevolking op of boven dit niveau.
