Plastic Peri on Species Diversity and Fish Catch: A Zone-wise Comparative Assessment between Ulhas River Estuary and Thane Creek.

Conference: Material and their Applications A Broad Perspective At: VPM's B. N. Bandodkar College of Science ThaneVolume: ISBN : 978-81-923628-7-8, 2020

The observation revealed that there is rise in plastic peril with increased anthropogenic activities which caused depletion in the fisheries of the ambient water bodies to non-profitable level. This consequently decreased the fishing activities. At 80% Bray-Curtis similarity resemblance in PCO showed that UZ-II, UZ-III and TZ-III were similar at 87.7% ordination in fish species abundance whereas UZ-III and TZ-III were similar at 89% ordination in biomass. The pattern of fish catches were in accordance with zone-wise deterioration level due to the impact of plastic peril which revealed direct correlation to that of dwindling status of the fisheries of the ambient water bodies.

BEHAVIOURAL STUDIES OF BOLEOPHTHALMUS DUSSUMIERI (VAL., 1837) ON THE SILTED INTERTIDAL MUDFLATS OF ULHAS RIVER ESTUARY

Boleophthalmus dussumieri (Val., 1837) is a mudskipper species of a common occurrence on the intertidal mudflats developed on either banks of URE. The present study recorded the various activities like burrow construction, feeding, territoriality and courtship, of B. dussumieri using scan and focal sampling method on the surface during tidal movements on the exposed mudflats of URE near Kolshet creek. Although the breeding and territoriality of B. dussumieri being normal, the other behavioral activities such as courtship, construction of burrows and survivorship were different as compared to the earlier observations by various experts. Breeding pairs preferred to develop burrows at spring tide limits. Burrows lacked chimneys and pit-pools. Juveniles remained without burrows and were found to secure position by penetration in loose soil during flood tide. Feeding on muddy surface was performed by strange straining behaviour.

Although the total number of species found in the Thane creek was high (67 spp.) as compared to Ulhas river estuary (58 spp.) the upper zone (I & II) of the former and zone I of later contain very low density of fish fauna. The salinity trend of zone-I of Thane creek is fairly nearer to zone-II od Ulhas river estuary but there is considerable difference in the fishery composition. It seems that various human activities like industrial effluent, domestic waste disposal, reclamation, sand dredging and eradication of mangrove flora have deteriorated these dynamic habitats causing decline in in their fin fish and shell fish fauna during last two decades. It has been observed that the mudskippers, prawns have completely eradicated from the entire stretch of the Thane crrek due to heavy industrial and domestic waste disposal although there is fairly good mangrove vegetation along its west bank. In case of Ulhas river estuary the sand dredging, occurring on its southern bank has forced the bottom dwellers like mud skippers, prawns & crabs to shift towards northern bank in zone II & III. A fairly good variety of fishery at the mouth of Thane creek and Ulhas river estuary indicated that timely implementation of mitigation measures may revive the fishery of the two ecosystems.

Most of the gears were designed indigenously to suit the availability of the amenable fishery species. The overall chronospatial pattern of frequency of gears operation was obtained using PRIMER v6 software. The use of gears was most frequent and diverse towards the lower reaches of the estuary. Late post-monsoon season was the most affluent in gear frequency. The important fishing methods used along the URE was 'vana' (barrier net), 'busa' (surface gill-net), 'dol' (stationary bag net) and 'malli' (basin method for capturing mudskippers on mud-flats). The fishing was carried for subsistence or artisanal levels at major while commercial fishing was highly reduced in URE. The reduced mesh sizes of the ambient gears portray the size of the species sought which depicted the threatening status of overall condition of fisheries in URE and requires a special attention for its rejuvenation.

Ambient hydrological conditions assessed during July 2005 to May 2006 and anthropogenic stresses are critical therefore leading to the decline in the fishery diversity as compared to earlier records. The abundant main fin-fishery species were replaced by the pollution tolerant species in due course of time. Several finfisheries have been obliterated in the estuary. Majority of the fishermen have abandoned the fishing practices due to non-productive status of the Ulhas river estuary fin-fisheries. The species diversity and species richness of the present diversity were conducive of the former observations.

A seasonal data, of total 119 and 104 specimens from the URE and TC respectively were collected for their stomach contents using point method, during Monsoon (MON), early post-monsoon (EPM), late post-monsoon (LPM) and pre-monsoon (PRM) seasons through July 2004 to June 2006. Food items were classified as polychaete worms (P Wo), insects (Ints), crustaceans (Cru), molluscs (Mol), others (Other) and non-food matters (NF). NF component was represented by coconut husk, eggshells, chicken feathers, pieces of brick, gravel, plastic etc. of anthropogenic origin. The percentage frequency of occurrence (F) revealed the predominance of P Wo, and Mol in both the water bodies, indicative of main food items. Feeding index (IA) shows high percentage of P Wo, Mol and NF in food composition of M. gulio (Ham.) which corroborates to vacuity index (VI). Both NF being compensatory food of M. gulio (Ham.) and conspicuous VI attribute to the higher pollution in TC as compared to URE.

A seasonal data of hydro-sedimentological parameters and total 119 and 104 specimens from the URE and TC respectively were collected for their stomach contents analysis using point method, during Monsoon (MON), early post-monsoon (EPM), late post-monsoon (LPM) and pre-monsoon (PRM) seasons from July 2004 to June 2006. The hydro-sedimentological parameters such as Suspended solids (SS), dissolved oxygen (DO), biochemical oxygen demand (BOD) and Organic C were recorded. Food items were classified as Polychaete worms (P Wo), insects (Ints), crustaceans (Cru), mollusks (Mol), others (Other) and non-food matters (NF). ‘NF’ component was represented by coconut husk, eggshells, chicken feathers, pieces of brick, gravel, plastic etc. of anthropogenic origin. The percentage frequency of occurrence (F) revealed the predominance of ‘P Wo’, and Mol in both the water bodies, indicative of main food items. Feeding index (IA) shows high percentage of ‘P Wo’, ‘Mol’ and ‘NF’ in food composition of M. gulio which attributed to vacuity index (VI). Both ‘NF’ being compensatory food and conspicuous VI in feeding of M. gulio ascribed to the higher pollution in TC as compared to URE. The food selection habit of M. gulio was corroborating with the pollution status of the ambient water bodies.

FOOD AND FEEDING HABIT OF BOLEOPHTHALMUS DUSSUMIERI (CUV. & VAL.) FROM ULHAS RIVER ESTUARY NEAR THANE CITY, MAHARASHTRA STATE

Abstract in Proceedings ‘Marine Coastal Biodiversity & Environment Pollution’, Mar 6, 2009

The estuarine environment are rich in primary production, therefore numerous fishes migrate to th... more The estuarine environment are rich in primary production, therefore numerous fishes migrate to the estuary for feeding purpose. Food and feeding habit of the fish in the estuary is of great importance to understand their life history including growth, breeding and migration and also for management of commercially important fisheries (Bal et al., 1984). Several experts have concentrated on the food and feeding habit of various fish in the world (Day, 1882; Mutsaddi, 1964; Qasim, 1972; Clayton, 1993; Wise, 1994; Connolly, 2004; Kitts, 2004).
The poor fishermen are mostly involved in the inward water fishery; therefore estuary is boon for their livelihood. In the Ulhas River estuary fishermen from localities in the vicinity such as Vehele, Sarang, Surai, Anjur, Diva-Kankavli, Alimghar, Dombivli, and Kasheli from Zone-I are involved in the mudskipper fishery. Fishing attempts were on vogue from monsoon to the early post-monsoon seasons frequenting from thrice to forth in a fortnight which however diminished towards the late post-monsoon to negligible level. An effort has been made to ordained food feeding of Boleopthalmus dussumieri (Cuv. &Val.) from Ulhas River estuary and to determine the fate of mudskipper fishery.
Herbivorous bottom feeder, Boleophthalmus dussumieri (Cuvier & Valencienne, 1837), an endemic to the Ulhas River estuary, found in the vicinity of Thane City. Boleophthalmus dussumieri (Cuv. & Val.), is the amphibious estuarine fish found flourishing in the mudflats of the of Ulhas River estuary. It is a benthic and burrowing type of fish inhabiting on the neretic mudflats of the Ulhas River estuary. These construct the burrows in the mud and feed on the mudflats. Although they often come out of water they restrict themselves nearby the water for breathing and other activities. Therefore their burrows are always constructed in the limits of intertidal zone (Mutsaddi, 1964; Chung et al. 1991; Clayton, 1993).
A season wise pooled data, from the ambient water, was procured for food and feeding habit of Boleopthalmus dussumieri (Cuv. &Val.), using point method, during the three seasons viz. monsoon (July – September, 2004); early post monsoon (October – December, 2004) and late post monsoon (January – march 2005).
