A Look about an Ornamental Shrimp, Stenopus Hispidus (Olivier, 1811)

By: Manu Madhavan , Ajith Kumar T. T , Kuldeep K. Lal

Page No : 1-19

Abstract
Marine aquarium keeping is one of the most popular hobbies, and it is an emerging sub-sector of the ornamental aquaculture industry, which is expected to grow more in the coming days. A variety of ornamental organisms are found in marine aquaria, which is attracting the attention of aquarists and hobbyists in recent years. The current review is focusing on the potential of an ornamental shrimp, Stenopus hispidus, its importance, distribution, geographical range, ecosystem role, the source for trade; captive/wild, market scenario, significant features, reproductive biology, functional morphology, and captive breeding. All Stenopus species are brightly colored and have been reported throughout the world, and majority of them are preferring for aquaria. Because of their prolonged chelated legs and spiny body, Stenopus are popularly referred to as “Boxing Shrimps”. Recently, the focus on marine ornamental shrimp aquaculture is getting attention towards the captive breeding of a few species, including Stenopus. Aquaculture of marine ornamentals is a significant and effective approach to protecting the coral ecosystem, also meeting commercial demand in the aquarium sector. Seven species of Stenopus are reported in the global aquarium trade, where S. hispidus is the most prominent one. S. hispidus has a lengthy larval duration lasting about 120 - 253 days. Many recent studies conducted globally have augmented the knowledge of their reproductive biology, feeding regimes, larviculture, and propagation process in captive conditions, which made significant advances in the past and present decades.

By: B. Ahilan , Cheryl Antony , Ahilan Kamalii , A. Jackqulinwino

Page No : 21-30

Abstract :
A 60-day feeding trial was carried out to investigate the effect of dietary replacement of fish meal with a plant protein source (Sunflower meal) on growth performance and digestive enzyme activities of Etroplus suratensis fingerling. Six isonitrogenous and isoenergetic diets were formulated with sunflower meal replacing fish meal at 0 (To), 7.5 (T7.5), 15 (T15), and 22.5% (T22.5) levels. The initial average weight of f ish was 5.48±0.01 g, which were distributed into (number of tanks) (60 l) at a stocking rate of 10 fish per tank. Each diet was fed to three replicate groups of fishes. Fish fed with 15% sunflower meal attained the highest weight gain, specific growth rate, average daily growth, the protein efficiency ratio (p<0.05) and protease activity. This study highlights the effective replacement of the fish meal with sunflower meal and investigates the influence of sunflower meal on the growth performance and digestive enzyme activity of Etroplus suratensis fingerlings.

Influence of Environmental Factors on Egg and Larvae Quality in Aquatic Animal Offspring

By: Ashish Sahu , Devarshi Ranjan , Satkar Sagar Gorakh , Shivaji Kanoujiya , Saiprasad Bhusare , Gowhar Iqbal

Page No : 77-90

Abstract
Egg and larvae quality are deeply influenced by various environmental factors, culture practices, and the domestication level of the species (Migaud et al., 2013). Environmental factors play a crucial role in the development and survival of eggs and larvae of aquatic animals such as fish, molluscs, octopus, squids, and sea turtles etc (Bobe et al., 2015). Some important environmental factors include temperature, food, pollutants, population density, sound, photoperiod (light), and parasites. All those factors can impact the growth, development, and overall health of these early life stages. Early larvae stages are the most crucial and vulnerable stages in the life cycle of fishes, and also affect the development, survival, and distribution and migration behaviour of larvae.

Freshwater Molluscs in the Gangetic Riverine System: Present Status of Diversity and Emerging Threats

By: Ashish Sahu , Pramila Sahadevan

Page No : 91-98

Abstract
Ganga basin is the largest river basin in India in terms of the catchment area, constituting more than 20% of the country’s landmass and supporting about more than 40% of its population. This mighty river is the home for some of the rarest and strangest animals on the planet. Previous documentations on the diversity of Himalayan rivers show that they are increasingly vulnerable to a wide variety of anthropogenic activities. The faunal components of the river, both invertebrates and vertebrates have been stressed due to a variety of reasons. Macroinvertebrates such as molluscs are a significant component of the riverine resources which also have a major role in maintaining the ecosystem health. As per studies conducted from November 2020 to October 2021, diversity of freshwater molluscs in this river has been recorded as 12 bivalves and ten gastropods. In this review impacts of major threats to Ganga river molluscs such as low water level, habitat destruction, agricultural runoff and pollution, over-harvesting, dams, urban development and sand mining have been discussed. Considerably lower diversity in comparison to other parts have been recorded in the middle stretch covering Prayagraj to Kanpur. Thus, it would be ideal to conduct comprehensive studies aiming at the assessment of diversity and conservation of molluscs in this river system. Despite the absence of organised fishery, the river Ganga, provides employment and livelihood support to the fisherfolk of adjacent villages. Hence it would be worthwhile to consider initiating efforts for improving the quality of this riverine system with well-defined action plans aiming at pollution abatement measures and sustainability of the resource.
