Pacific Fisheries
module 5 PACIFIC FISHERIES 80 MODULE 5 PACIFIC FISHERIES 5.0 FISHERIES IN THE PACIFIC Fish and fishing are culturally and economically critical for most PICTs and are a mainstay of food security in the region. The importance of the fisheries sector to the region’s economy and food security is reflected by its reference in key regional strategies including The Pacific Plan and the Vava’u Declaration on Pacific Fisheries Resources. (See TOOLS 51 & 52.) In the Pacific, a great variety of marine organisms are consumed. In Fiji, for example, over 100 species of finfish and 50 species of invertebrates are officially included in the fish market statistics, and many more species are believed to contribute to the diets of people in rural and urban areas of the Pacific. Fish5 contributes substantially to subsistence and market-based economies and, for some of the smaller PICTs, fishing is their most important renewable resource. Despite growing reliance on imported food products, subsistence fishing still provides the majority of dietary animal protein in the region, and annual per capita consumption of fish ranges from an estimated 13 kg in Papua New Guinea to more than 110 kg in Tuvalu (Table 5.1). According to forecasts of the fish that will be required in 2030 to meet recommended per capita fish consumption in PICTs (34-37 kg/year), or to maintain current consumption levels, coastal fisheries will be able to meet 2030 demand in only 6 of 22 PICTs. Supply is likely to be either marginal or insufficient in the remaining 16 countries, which include the region’s most populous nations of Papua New Guinea, Fiji, Solomon Islands, Samoa and Vanuatu, as shown in Table 5.1. -

J. mar. biol. Ass. U.K. (1958) 37, 7°5-752 Printed in Great Britain OBSERVATIONS ON LUMINESCENCE IN PELAGIC ANIMALS By J. A. C. NICOL The Plymouth Laboratory (Plate I and Text-figs. 1-19) Luminescence is very common among marine animals, and many species possess highly developed photophores or light-emitting organs. It is probable, therefore, that luminescence plays an important part in the economy of their lives. A few determinations of the spectral composition and intensity of light emitted by marine animals are available (Coblentz & Hughes, 1926; Eymers & van Schouwenburg, 1937; Clarke & Backus, 1956; Kampa & Boden, 1957; Nicol, 1957b, c, 1958a, b). More data of this kind are desirable in order to estimate the visual efficiency of luminescence, distances at which luminescence can be perceived, the contribution it makes to general back• ground illumination, etc. With such information it should be possible to discuss. more profitably such biological problems as the role of luminescence in intraspecific signalling, sex recognition, swarming, and attraction or re• pulsion between species. As a contribution to this field I have measured the intensities of light emitted by some pelagic species of animals. Most of the work to be described in this paper was carried out during cruises of R. V. 'Sarsia' and RRS. 'Discovery II' (Marine Biological Association of the United Kingdom and National Institute of Oceanography, respectively). Collections were made at various stations in the East Atlantic between 30° N. and 48° N. The apparatus for measuring light intensities was calibrated ashore at the Plymouth Laboratory; measurements of animal light were made at sea. -
Spatial and Temporal Distribution of the Demersal Fish Fauna in a Baltic Archipelago As Estimated by SCUBA Census
MARINE ECOLOGY - PROGRESS SERIES Vol. 23: 3143, 1985 Published April 25 Mar. Ecol. hog. Ser. 1 l Spatial and temporal distribution of the demersal fish fauna in a Baltic archipelago as estimated by SCUBA census B.-0. Jansson, G. Aneer & S. Nellbring Asko Laboratory, Institute of Marine Ecology, University of Stockholm, S-106 91 Stockholm, Sweden ABSTRACT: A quantitative investigation of the demersal fish fauna of a 160 km2 archipelago area in the northern Baltic proper was carried out by SCUBA census technique. Thirty-four stations covering seaweed areas, shallow soft bottoms with seagrass and pond weeds, and deeper, naked soft bottoms down to a depth of 21 m were visited at all seasons. The results are compared with those obtained by traditional gill-net fishing. The dominating species are the gobiids (particularly Pornatoschistus rninutus) which make up 75 % of the total fish fauna but only 8.4 % of the total biomass. Zoarces viviparus, Cottus gobio and Platichtys flesus are common elements, with P. flesus constituting more than half of the biomass. Low abundance of all species except Z. viviparus is found in March-April, gobies having a maximum in September-October and P. flesus in November. Spatially, P. rninutus shows the widest vertical range being about equally distributed between surface and 20 m depth. C. gobio aggregates in the upper 10 m. The Mytilus bottoms and the deeper soft bottoms are the most populated areas. The former is characterized by Gobius niger, Z. viviparus and Pholis gunnellus which use the shelter offered by the numerous boulders and stones. The latter is totally dominated by P. -
Are Deep-Sea Fisheries Sustainable? a Summary of New Scientific Analysis: Norse, E.A., S
RESEARCH SERIES AUGUST 2011 High biological vulnerability and economic incentives challenge the viability of deep-sea fisheries. ARE DEEP-SEA FISHERIES SUSTAINABLE? A SUMMARY OF NEW SCIENTIFIC AnaLYSIS: Norse, E.A., S. Brooke, W.W.L. Cheung, M.R. Clark, I. Ekeland, R. Froese, K.M. Gjerde, R.L. Haedrich, S.S. Heppell, T. Morato, L.E. Morgan, D. Pauly, U. R. Sumaila and R. Watson. 2012. Sustainability of Deep-sea Fisheries. Marine Policy 36(2): 307–320. AS COASTAL FISHERIES have declined around the world, fishermen have expanded their operations beyond exclusive economic zones (EEZs) to the high seas beyond EEZs, including the deep sea. Although the deep sea is the largest yet least ecologically productive part of the ocean, seamounts and other habitats can host significant amounts of some deep- sea fish species, especially when they aggregate to breed and feed. Many deep-sea fishes are slow to reproduce, or produce young only sporadically, however, making commercial fisheries unsustainable. Dr. Elliott Norse of the Marine Conservation Institute and a multidisciplinary team of co-authors analyzed data on fishes, fisheries and deep-sea biology and assessed key economic drivers and international laws to determine whether deep-sea commercial fishing could be sustainable. Ultimately, the authors conclude that most deep-sea fisheries are unsustainable, especially on the high seas. This Lenfest Research Series report is a summary of the scientists’ findings. DEEP-SEA FISHERIES As coastal fisheries have declined, fishing in the deep sea has increased. Technological advances have enabled fishing vessels to travel further from shore and locate aggregations of fish in depths that were unreachable years ago (see graphic). -
Fish Species and for Eggs and Larvae of Larger Fish
BATIQUITOS LAGOON FOUNDATION F I S H Fishes of the Lagoon There were only a few species of fish in Batiquitos Lagoon (just five!) BATIQUITOS LAGOON FOUNDATION before it was opened to the ocean and tides at the end of 1996. High temperatures in the summer, low oxygen levels, and wide ranges of ANCHOVY salinity did not allow the ecosystem to flourish. Since the restoration of tidal action to the lagoon, the fish populations have significantly increased in numbers and diversity and more than sixty-five species have been found. Lagoons serve as breeding and nursery areas for a wide array of coastal fish, provide habitat and food for resident species TOPSMELT and serve as feeding areas for seasonal species. Different areas of the lagoon environment provide specific habitat needs. These include tidal creeks, sandy bottoms, emergent vegetation, submergent vegetation, nearshore shallows, open water, saline pools and brackish/freshwater areas. These habitats are defined by water YELLOWFIN GOBY characteristics including salinity, water temperature, water velocity and water depth. The lagoon bottom varies with the type of substrate such as rock, cobble, gravel, sand, clay, mud and silt. Tidal creeks and channels provide refuges for small fish species and for eggs and larvae of larger fish. Species in tidal creeks include ROUND STINGRAY gobies and topsmelt. Sandy bottoms provide important habitat for bottom-dwelling fish species such as rays, sharks and flatfish. The sandy areas provide important refuges for crustaceans, which are prey to many fish species within the lagoon. The burrows of ghost shrimp are utilized by the arrow goby. -

Comparison of an Active and a Passive Age-0 Fish Sampling Gear in a Tropical Reservoir
Comparison of an Active and a Passive Age-0 Fish Sampling Gear in a Tropical Reservoir M. Clint Lloyd, Department of Wildlife, Fisheries and Aquaculture, Mississippi State University, Box 9690 Mississippi State, MS 39762 J. Wesley Neal, Department of Wildlife, Fisheries and Aquaculture, Mississippi State University, Box 9690 Mississippi State, MS 39762 Abstract: Age-0 fish sampling is an important tool for predicting recruitment success and year-class strength of cohorts in fish populations. In Puerto Rico, limited research has been conducted on age-0 fish sampling with no studies addressing reservoir systems. In this study, we compared the efficacy of passively-fished light traps and actively-fished push nets for sampling the limnetic age-0 fish community in a tropical reservoir. Diversity of catch between push nets and light traps were similar, although species composition of catches differed between gears (pseudo-F = 32.21, df =1,23, P < 0.001) and among seasons (pseudo-F = 4.29, df = 3,23, P < 0.006). Push-net catches were dominated by threadfin shad (Dorosoma petenense), comprising 94.2% of total catch. Conversely, light traps collected primarily channel catfish Ictalurus( punctatus; 76.8%), with threadfin shad comprising only 13.8% of the sample. Light-trap catches had less species diversity and evenness compared to push nets, consequently their efficiency may be limited to presence/ absence of species. These two gears sampled different components of the age-0 fish community and therefore, gear selection should be based on- re search goals, with push nets an ideal gear for threadfin shad age-0 fish sampling, and light traps more appropriate for community sampling. -
Composition of Ichthyoplankton and Horizontal and Vertical Distribution of Fish Larvae in the Great Meteor Seamount Area in September 1998
Not to be cited without prior reference to the author ICES/ASC CM 2002/M12 Theme Session on Oceanography and Ecology of Seamounts – Indications of Unique Ecosystems Composition of ichthyoplankton and horizontal and vertical distribution of fish larvae in the Great Meteor Seamount area in September 1998 by Walter Nellen & Silke Ruseler Inst. of Hydrobiology and Fisheries Science Hamburg University Abstract 24 stations above and near the Great Meteor Seamount, central north Atlantic, have been sampled at eight depth strata in late summer 1998 by a modified MOCNESS. Some 18.800 fish larvae were collected and specimens were identified to species and coarser systematic levels, respectively. Taxa typical of the high sea remote from coastal areas dominated the fish larvae assembly. But species which normally are found on the shelf or at the slope occurred as well in the plankton samples, mainly above and fairly close to the 300m deep seamount, obviously keeping away from the oceanic region several thousand meters deep. Eighteen of a total of more than 150 identified fish larvae taxa belonged to the neritic province. One of these species was the third most abundant larvae found so far during this investigation, namely Chlorophthalmus agassizii. Concentration and horizontal and vertical distribution of selected species are discussed as well as migration behaviour in dependence of day and night situation and sea bottom depth. It is considered whether this seamount may be regarded as an isolated, just 1465km² large shallow water area settled permanently by a coastal fish community. The question is treated why this may be so, i.e. -

Snapper and grouper are important fishery resources with great commercial value for exporters to major international markets. The fisheries also support the livelihoods and food security of many local, small-scale fishing communities worldwide. It is therefore all the more critical that management of these fisheries improves, thus ensuring this important resource will remain available to provide both food and income. Landings of snapper and grouper have been steadily increasing: in the 1950s, total landings were about 50,000 tonnes, but they had grown to more than 612,000 tonnes by 2013. -

Seafood Watch® defines sustainable seafood as originating from sources, whether wild-caught or farmed, which can maintain or increase production in the long-term without jeopardizing the structure or function of affected ecosystems. Seafood Watch® makes its science-based recommendations available to the public in the form of regional pocket guides that can be downloaded from the Internet (seafoodwatch.org) or obtained from the Seafood Watch® program by emailing [email protected]. The program’s goals are to raise awareness of important ocean conservation issues and empower seafood consumers and businesses to make choices for healthy oceans. Each sustainability recommendation on the regional pocket guides is supported by a Seafood Report. Each report synthesizes and analyzes the most current ecological, fisheries and ecosystem science on a species, then evaluates this information against the program’s conservation ethic to arrive at a recommendation of “Best Choices”, “Good Alternatives” or “Avoid.” The detailed evaluation methodology is available upon request. -
Lane Snapper (Lutjanus Synagris)
Tab B, No. 8(b) 2/18/2020 Lane Snapper (Lutjanus synagris) Description: Lane snapper is a member of the snapper family (Lutjanidae). It is typically almond-shaped, colored pink- red around the edges with a silvery body color, and has a number of pink and yellow lines running along the body from head to tail. It often has a distinctive spot on its upper side and can be easily confused with mutton snapper. The Gulf of Mexico stock is distinct from the Atlantic. Lane snapper occurs in a variety of habitats such a reefs and inshore sandy bottom vegetated habitats. Lane snapper are experiencing overfishing (2019) but its stock status is Photo credit: Dylan Hubbard unknown (SEDAR 49 2016). Gulf Stock Characteristics: (SEDAR 49 2016) Natural mortality rate (M): 0.33/year (max. age of 19 years) Reproductive maturity: 50% of females are mature at ~9 inches (24.0 cm) fork length (FL); ~age 1-2 Maximum age: 19 years Maximum weight: 13 lbs (5.9 kg) whole weight Maximum length: 18 inches (44.9 cm) FL Discard mortality: 5-15% (fleet dependent) Life History and Distribution: (SEDAR 49 2016) Lane snapper is distributed from the North Atlantic off North Carolina through the Gulf of Mexico and Caribbean to Southern Brazil. It generally feeds at night and preys upon a variety of species such as smaller fish, shrimp, and crabs. Peak spawning occurs along shelf habitats from June through August. Larvae settle around 21-66 days on near-shore shell ridge habitats as well as muddy habitats. Adults often occur in high- relief offshore habitats in water depths up to 430 feet (~132 meters) and in areas with high salinity (>30 psu) with variable water temperatures (16-29 ̊C). -
