Status of Taal Lake Fishery Resources with Emphasis on the Endemic Freshwater Sardine, Sardinella Tawilis (Herre, 1927)
The Philippine Journal of Fisheries 25Volume (1): 128-135 24 (1-2): _____ January-June 2018 JanuaryDOI 10.31398/tpjf/25.1.2017C0017 - December 2017 Status of Taal Lake Fishery Resources with Emphasis on the Endemic Freshwater Sardine, Sardinella tawilis (Herre, 1927) Maria Theresa M. Mutia1,*, Myla C. Muyot1,, Francisco B. Torres Jr.1, Charice M. Faminialagao1 1National Fisheries Research and Development Institute, 101 Corporate Bldg., Mother Ignacia St., South Triangle, Quezon City ABSTRACT Assessment of fisheries in Taal Lake was conducted from 1996-2000 and 2008-2011 to know the status of the commercially important fishes with emphasis on the endemic freshwater sardine,Sardinella tawilis. Results of the fish landed catch survey in 11 coastal towns of the lake showed a decreasing fish harvest in the open fisheries from 1,420 MT to 460 MT in 1996 to 2011. Inventory of fisherfolk, boat, and gear also decreased to 16%, 7%, and 39%, respectively from 1998 to 2011. The most dominant gear is gill net which is about 53% of the total gear used in the lake with a declining catch per unit effort (CPUE) of 11kg/day to 4 kg/day from 1997 to 2011. Active gear such as motorized push net, ring net, and beach seine also operated in the lake with a CPUE ranging from 48 kg/day to 2,504 kg/day. There were 43 fish species identified in which S. tawilis dominated the catch for the last decade. However, its harvest also declined from 744 to 71 mt in 1996 to 2011. The presence of alien species such as jaguar fish, pangasius, and black-chinned tilapia amplified in 2009. -

Trematodes, Cestodes, Abstract Protozoans, A survey of Schilbe mystus of the mid Cross River flood system was conducted between Acanthocephalans, August and October, 2014 to determine the presence of parasitic infection in S. mystus . Schilbe mystus The fish were collected with gill nets, hook and line. Seventy five out of the one hundred fish examined were infected (75.0%) with parasites. The end oparasites recovered were mostly nematodes, trematodes, cestodes, protozoa and acanthocephalans. Numerical abundance of parasites showed that a total of 128 species of end oparasites occurred in Received: June 30, 2015 the fish examined. Nematodes had 33.6% (43/128), trematodes 11.7% (15/128), Revised: July 10, 2015 cestodes 24.2% (31/128), protozoa 12.5% (16/128) and acanthocephalan 18.0% Accepted: July 11, 2015 (23/128). The prevalence of end oparasites of the fish showed that parasites were most prevalent in fishes with length Class 14.1-16 cm TL with 67.2% while class 21.1-22cm had the least prevalence (1.60%). -
ABSTRACT Anchoviella Vaillanti
Volume 45(esp.):33‑40, 2014 REDESCRIPTION OF THE FRESHWATER ANCHOVY ANCHOVIELLA VAILLANTI (STEINDACHNER, 1908) (CLUPEIFORMES: ENGRAULIDAE) WITH NOTES ON THE DISTRIBUTION OF ESTUARINE CONGENERS IN THE RIO SÃO FRANCISCO BASIN, BRAZIL 1,2 MARINA VIANNA LOEB 1,3 JOSÉ LIMA DE FIGUEIREDO ABSTRACT Anchoviella vaillanti (Steindachner, 1908) was described based on few specimens from the middle Rio São Francisco; however, several specimens of the species have been collected in recent decades. The range of morphological variation of A. vaillanti could thus be reassessed based on a larger number of specimens currently available in fish collections, and the species redescribed. Anchoviella vaillanti can be recognized among freshwater congeners by the relative position of the pelvic, dorsal and anal fins. Records of the species in ichthyological collections are restricted to the upper and middle portions of the Rio São Francisco basin, but the species might also occur in the lower Rio São Francisco. Comments on the distribution of the marine species of Anchoviella from the lower Rio São Francisco basin and an identification key including those species and A. vaillanti are provided.

NC-Anchovy-And-Identification-Key
Anchovy (Family Engraulidae) Diversity in North Carolina By the NCFishes.com Team Engraulidae is a small family comprising six species in North Carolina (Table 1). Their common name, anchovy, is possibly from the Spanish word anchova, but the term’s ultimate origin is unclear (https://en.wiktionary.org/wiki/anchovy, accessed December 18, 2020). North Carolina’s anchovies range in size from about 100 mm Total Length for Bay Anchovy and Cuban Anchovy to about 150 mm Total Length for Striped Anchovy (Munroe and Nizinski 2002). Table 1. Species of anchovies found in or along the coast of North Carolina. Scientific Name/ Scientific Name/ American Fisheries Society Accepted Common Name American Fisheries Society Accepted Common Name Engraulis eurystole - Silver Anchovy Anchoa mitchilli - Bay Anchovy Anchoa hepsetus - Striped Anchovy Anchoa cubana - Cuban Anchovy Anchoa lyolepis - Dusky Anchovy Anchoviella perfasciata - Flat Anchovy We are not aware of any other common names applied to this family, except for calling all of them anchovies. But as we have learned, each species has its own scientific (Latin) name which actually means something (please refer to The Meanings of the Scientific Names of Anchovies, page 9) along with an American Fisheries Society-accepted common name (Table 1; Page et al. 2013). Anchovies from large schools of fishes that feed on zooplankton. In North Carolina they may be found in all coastal basins, nearshore, and offshore (Tracy et al. 2020; NCFishes.com [Please note: Tracy et al. (2020) may be downloaded for free at: https://trace.tennessee.edu/sfcproceedings/vol1/iss60/1.] All species are found in saltwater environments (Maps 1-6), but Bay Anchovy is a seasonal freshwater inhabitant in our coastal rivers as far upstream as near Lock and Dam No. -

Anchoa Mitchilli) Eggs and Larvae in Chesapeake Bay ) E.W
Estuarine, Coastal and Shelf Science 60 (2004) 409e429 www.elsevier.com/locate/ECSS Distribution and transport of bay anchovy (Anchoa mitchilli) eggs and larvae in Chesapeake Bay ) E.W. North , E.D. Houde1 University of Maryland Center for Environmental Science, Chesapeake Biological Laboratory, USA Received 28 February 2003; accepted 8 January 2004 Abstract Mechanisms and processes that influence small-scale depth distribution and dispersal of bay anchovy (Anchoa mitchilli) early-life stages are linked to physical and biological conditions and to larval developmental stage. A combination of fixed-station sampling, an axial abundance survey, and environmental monitoring data was used to determine how wind, currents, time of day, physics, developmental stage, and prey and predator abundances interacted to affect the distribution and potential transport of eggs and larvae. Wind-forced circulation patterns altered the depth-specific physical conditions at a fixed station and significantly influenced organism distributions and potential transport. The pycnocline was an important physical feature that structured the depth distribution of the planktonic community: most bay anchovy early-life stages (77%), ctenophores (72%), copepod nauplii (O76%), and Acartia tonsa copepodites (69%) occurred above it. In contrast, 90% of sciaenid eggs, tentatively weakfish (Cynoscion regalis), were found below the pycnocline in waters where dissolved oxygen concentrations were !2.0 mg lÿ1. The dayenight cycle also influenced organism abundances and distributions. Observed diel periodicity in concentrations of bay anchovy and sciaenid eggs, and of bay anchovy larvae O6 mm, probably were consequences of nighttime spawning (eggs) and net evasion during the day (larvae). Diel periodicity in bay anchovy swimbladder inflation also was observed, indicating that larvae apparently migrate to surface waters at dusk to fill their swimbladders.
