Le Bris), http://umaine.edu/wahlelab/current-projects/american-lobster-settlement-index/ Several months now into the COVID-19 pandemic, we can only look back to the 2019 fishing year with some nostalgia. In calendar year 2019, Canadian lobster landings continued to boast near all-time highs. And while US landings have slipped a bit from their own historic highs, much of those losses have been offset by continued high value. That is, until now. All that changed almost overnight with the onset of the pandemic, as demand for lobster plummeted with shuttered restaurants and overseas commerce, dragging down the price of lobster, much to the distress of fishing communities up and down the coast. As we enter the 2020 summer fishing season, the lobster industry grapples to find a new normal as it accommodates health protocols, readjusts markets and scales back revenue expectations. In kind, state and federal marine resource monitoring programs are equally rethinking sampling programs under shrinking tax revenues and new safety standards. Last year’s Update examined how well ALSI predicted trends in the fishery from Fundy to Rhode Island. -
American Eel (Anguilla Rostrata)
Indiana Division of Fish and Wildlife’s Animal Information Series American Eel (Anguilla rostrata) Do they have any other names? The names “glass eel” or “elver” are used to describe young, developing eels. Why are they called American eels? The closest relatives to the American eel are other freshwater eels found in Europe and Asia; therefore they are called American eels because they are only in America. Anguilla is the Latin name for eel and rostrata is Latin for “beaked,” in reference to the snout. What do they look like? American eels are a brownish-colored fish with a slender, snake-like body and a small, pointed head. The body appears smooth and mucousy; however there are small scales present. They have a long dorsal fin that is more than half the length of the body and attached to the tail and anal fins. American eels do not have pelvic fins, but do have pectoral fins (on the sides near the head). The lower jaw projects farther than the upper jaw and they have many small teeth. Photo Credit: Duane Raver/USFWS 2012-MLC Page 1 Where do they live in Indiana? American eels are rare in Indiana and are found in large streams and rivers. They can sometimes be found in ponds or lakes that are not connected to a river, although this seldom happens. What kind of habitat do they need? American eels are found in large streams or rivers with continuous flow and clear water. During the day eels like to stay near logs, boulders, or other cover. -

There is much variation within in the US. There are about 200 Florida producers who and among fish groups with regard to acceptable water collectively raise over 800 varieties of freshwater fishes.

Some farms specialize in one or a few fish was about US$47.2 million. Given the additional economic groups, while other farms produce a wide spectrum of effects of tropical fish trade such as support industries, aquatic livestock. wholesalers, retail pet stores, and aquarium product manufacturing, the importance to Florida is tremendous. Fish can be grouped in a number of different ways. One major division in the industry which has practical signifi- Florida’s tropical ornamental aquaculture industry is cance is that between egg-laying species and live-bearing concentrated in Hillsborough, Polk, and Miami-Dade species.

Historic factors, warm climate, the proxim- ity to airports and other infrastructural considerations This publication briefly reviews the more common groups (ready access to aquaculture equipment, supplies, feed, etc.) of freshwater tropical ornamental fishes cultured in Florida are the major reasons for this distribution. -
Hormone-Induced Spawning of Cultured Tropical Finfishes
ADVANCES IN TROPICAL AQUACULTURE. Tahiti, Feb. 20 - March 4 1989 AQUACOP 1FREMER Acres de Colloque 9 pp. 519 F39 49 Hormone-induced spawning of cultured tropical finfishes C.L. MARTE Southeast Asian Fisheries Development Genie. Aquaculture Department, Tig- bauan, ILOILO, Philippines Abstract — Commercially important tropical freshwater and marine finfishes are commonly spawned with pituitary homogenate, human chorionic gonadotropin (HCG) and semi-purified fish gonadotropins. These preparations are often adminis- tered in two doses, a lower priming dose followed a few hours later by a higher resolving dose. Interval between the first and second injections may vary from 3 - 24 hours depending on the species. Variable doses are used even for the same species and may be due to variable potencies of the gonadotropin preparations. Synthetic analogues of luteinizing hormone-releasing hormone (LHRHa) are becoming widely used for inducing ovulation and spawning in a variety of teleosts. For marine species such as milkfish, mullet, sea bass, and rabbitfish, a single LHRHa injection or pellet implant appears to be effective. Multiple spawnings of sea bass have also been obtained following a single injection or pellet implant of a high dose of LHRHa. In a number of freshwater fishes such as the cyprinids, LHRHa alone however has limited efficacy. Standardized methods using LHRHa together with the dopamine antagonists pimozide, domperidone and reserpine have been developed for various species of carps. The technique may also be applicable for spawning marine teleosts that may not respond to LHRHa alone or where a high dose of the peptide is required. Although natural spawning is the preferred method for breeding cultivated fish, induced spawning may be necessary to control timing and synchrony of egg production for practical reasons. -

Seriola Dumerili (Greater Amberjack)
UWI The Online Guide to the Animals of Trinidad and Tobago Diversity Seriola dumerili (Greater Amberjack) Family: Carangidae (Jacks and Pompanos) Order: Perciformes (Perch and Allied Fish) Class: Actinopterygii (Ray-finned Fish) Fig. 1. Greater amberjack, Seriola dumerili. [http://portal.ncdenr.org/web/mf/amberjack_greater downloaded 20 October 2016] TRAITS. The species Seriola dumerili displays rapid growth during development as a juvenile progressing to an adult. It is the largest species of the family of jacks. At adulthood, S. dumerili would typically weigh about 80kg and reach a length of 1.8-1.9m. Sexual maturity is achieved between the age of 3-5 years, and females may live longer and grow larger than males (FAO, 2016). S. dumurili are rapid-moving predators as shown by their body form (Fig. 1) (FLMNH, 2016). The adult is silvery-bluish in colour, whereas the juvenile is yellow-green. It has a characteristic goldish side line, as well as a dark band near the eye, as seen in Figs 1 and 2 (FAO, 2016; MarineBio, 2016; NCDEQ, 2016). DISTRIBUTION. S. dumerili is native to the waters of Trinidad and Tobago. Typically pelagic, found between depths of 10-360m, the species can be described as circumglobal. In other words, it is found worldwide, as seen in Fig. 3, though much more rarely in some areas, for example the eastern Pacific Ocean (IUCN, 2016). Due to this distribution, there is no threat to the population of the species, despite overfishing in certain locations. Migrations do occur, which are thought to be linked to reproductive cycles. -

A5 By-catch Species APPENDIX 5: BY-CATCH SPECIES A.5 By-catch species By-catch is the unintentional/incidental capture of non-target species during fishing operations. Different types of fisheries have different types and levels of by-catch, depending on the gear used, the time, area and depth fished, etc. Article IV of the Convention states: "the Commission shall be responsible for the study of the population of tuna and tuna-like fishes (the Scombriformes with the exception of Trichiuridae and Gempylidae and the genus Scomber) and such other species of fishes exploited in tuna fishing in the Convention area as are not under investigation by another international fishery organization". The following is a list of by-catch species recorded as being ever caught by any major tuna fishery in the Atlantic/Mediterranean. Note that the lists are qualitative and are not indicative of quantity or mortality. Thus, the presence of a species in the lists does not imply that it is caught in significant quantities, or that individuals that are caught necessarily die.
