Aspects of the Life History of Hornyhead Turbot, Pleuronichthys Verticalis, Off Southern California
Aspects of the Life History of Hornyhead Turbot, Pleuronichthys verticalis, off Southern California he hornyhead turbot T(Pleuronichthys verticalis) is a common resident flatfish on the mainland shelf from Magdalena Bay, Baja Califor- nia, Mexico to Point Reyes, California (Miller and Lea 1972). They are randomly distributed over the bottom at a density of about one fish per 130 m2 and lie partially buried in the sediment (Luckinbill 1969). Hornyhead turbot feed primarily on sedentary, tube-dwelling polychaetes (Luckinbill 1969, Allen 1982, Cross et al. 1985).

Cuddalore-Dt, Tamilnadu, India Government Arts College, Viruthachalam Submitted: 31 Jan 2020 Accepted: 05 Feb 2020; Published: 07 Mar 2020 Abstract Bycatch and discards are common and pernicious problems faced by all fisheries globally. It is recognized as unavoidable in any kind of fishing but the quantity varies according to the gear operated. In tropical countries like India, bycatch issue is more complex due to the multi-species and multi-gear nature of the fisheries. Among the different fishing gears, trawling accounts for a higher rate of bycatch, due to comparatively low selectivity of the gear. A study was conducted during June 2018 - Dec 2019 in the Mudasalodai fish landing centre, southeast coast of India. During the study period six sp. of flat fishes collected and identified taxonomically. Keywords: Flat fish, tongue fish, sole fish, bycatch, fish landing, waters of Parangipettai. The study was conducted for a period of diversity, taxonomy one and half year (June 2018 - Dec 2019), no sampling was done in the month of May, due to the fishing holiday in the coast of Introduction Tamil Nadu.

Specimens were divided into two groups based on the number of elongated dorsal fin rays on the top of the head: Cynoglossidae sp. A was defined as having two elongated dorsal fin rays, while Cynoglossidae sp. B possessed a single elongated dorsal fin ray. One specimen of Cynoglossidae sp. A, a post-larva with a notochord length (NL) of 5.8 mm was thought to be a Cynoglossus joyneri larva based on the presence of 115 dorsal pterogiophores, 85 anal pterogiophores, and 50 myomeres. Two specimens of Cynoglossidae sp. B, a 4.1 mm NL larva and a 11.3 mm NL juvenile, were thought to be Cynoglossus abbreviatus based on the presence of yolk in the former and 133 dorsal fin rays, 105 anal fin rays, and 63 myomeres in the latter. To test this morphology-based identification, molecular analysis was conducted using 419-422 bp of mitochondrial DNA 16S rRNA. Cynoglossidae sp. A was clearly matched to a Cynoglossus joyneri adult (d=0.000) and Cynoglossidae sp. B clustered closely with Cynoglossus abbreviatus adults (d=0.002). -

Abstract: Bony fish includes the largest groups of fishes that have high economic value. Among these fish the Pleuronectiformes order have about 678 extant species that are recognized in approximately 134 genera and 14 families. Among the tonguefishes (Cynoglossidae) family, the species of Cynoglossus arel has remarkable distribution in Persian Gulf region. The purpose of this study was to determine the timing and duration of the spawning season from the monthly data on the incidence of changes in the gonadosomatic index (GSI), hepatosomatic index (HSI) and condition factor (K). In this study a total of 905 C. arel specimens were collected from the coastal waters of Bandar Abbas, south coast of Iran (27˚17’N, 56˚26’E) from October 2009 to September 2010. Then, in laboratory total length, body weight and sex were recorded, also gonads and liver were removed and weighted. The average of total length and total weight in males were 210.6 ± 1.91 mm and 43.0 ± 1.19 g, also the average of total length and total weight in females were 226.1 ± 1.81 mm and 54.2 ± 1.41 g. -

More than 80 recent references relating to Philippine flatfish are assembled. Various biological inferences are drawn from the small sizes typical of Philippine (and tropical) flatfish, and pertinent to the "systems dynamics of flatfish". This was facilitated by FishBase, which documents all data presented here, and which was used to generate the graphs supporting these biological inferences. INTRODUCTION Taxonomy, in its widest sense, is at the root of every scientific discipline, which must first define the objects it studies. Then, the attributes of these objects can be used for various classificatory and/or interpretive schemes; for example, the table of elements in chemistry or evolutionary trees in biology. Fisheries science is no different; here the object of study is a fishery, the interaction between species and certain gears, deployed at certain times in certain places. -
