Piglet survival is of importance because it affects the farmer?s economy and the welfare of the pigs. There are several factors affecting piglet survival and they are often linked to each other. This paper will focus on how the behaviour of the sow can affect the growth and survival of the piglets and possible causations of differences in maternal behaviour. Sows in intensive production systems have different possibilities to express their maternal behaviour than free ranging sows. They often live in small pens or crates, have fewer choices because of the restricted environment, and are depended on human provided resources. One of the major problems in piglet production is that piglets are crushed by the sow and then dies from traumatic injury or suffocation. Sow behaviour when she lies down or when she has a piglet under her body affects the mortality and the risk of injures on piglets. Also, sow behaviour during farrowing can affect piglet survival in a positive or negative way. There are differences in nursing patterns between sows. The variation in maternal behaviour between sows can therefore be of interest, to find a way to reduce piglet mortality and increase growth.

India's ornamental fisheries sector holds substantial promise for economic growth and job creation, supporting livelihoods across the country. While the domestic market is valued at approximately INR 500 crores, the sector's development is hampered by several challenges. These constraints include production issues like inconsistent breeding practices and inadequate feed, infrastructure limitations such as unreliable utilities and high costs, marketrelated problems like poor infrastructure and fluctuating demand, and institutional barriers such as limited access to credit. These challenges vary regionally. For example, Kolkata struggles with traditional practices and infrastructure deficits, Chennai with limited credit and extension support, and Mumbai with high costs and market access difficulties. To achieve sustainable growth, targeted strategies are needed. These include developing infrastructure, building capacity through training, providing institutional support, improving market linkages, empowering producers through organizations, and implementing supportive policies. Addressing these constraints will enable India to fully capitalize on the sector's potential.

Invasive species pose a serious ecological and economic threat to various natural and manmade ecosystems, often remaining unrecognized until their effects become severe and irreversible. Conventional monitoring techniques such as frequent netting, trapping, visual surveys, and morphological identification are time-consuming, labour-intensive and costlier approaches. They are often inefficient in identifying species at low abundance or early developmental stages. Environmental DNA (eDNA)-based techniques offer a sensitive, noninvasive, and cost-effective alternative for the early detection and improved surveillance of invasive species. This technique detects species without direct observation or capture by collecting and analysing DNA that organisms release into their environments (such as water, soil or sediment). Environmental DNA combined with advanced molecular techniques like high-throughput sequencing and quantitative PCR enables precise species identification and real-time detection in challenging environments, combined with advanced molecular techniques like high-throughput sequencing and quantitative PCR. This article highlights using an eDNA-based approach for effectively monitoring and detecting invasive species at an earlier stage.
